How Do Ultrasonic Thickness Gauges Work?

What Is An Ultrasonic Thickness Gauge?

Ultrasonic thickness gauges are digital devices used to measure the thickness of a material by construction professionals. Thickness gauges provide quick, accurate measurement within fractions of a millimeter, and they can be used on virtually any type of common construction material.

How Digital Thickness Gauges Work

Ultrasonic thickness gauges measure thickness by sending sound waves through a target material. Essentially, the device emits a high-frequency sound wave – which is much higher than the waves humans hear – and the gauge measures how long the wave takes to pass through a material and bounce back.

If you were measuring a steel pipe, for example, the thickness gauge would send a wave that travels through the material, and then calculates the thickness based on the time it takes to receive the echo from the back wall of the pipe. Due to this technology, ultrasonic thickness gauges are extremely precise; some models can record accurate measurements within fractions of a millimeter.

Types of Materials You Can Measure with a Thickness Gauge

Commercial thickness gauges can be used to measure all types of materials, including common construction materials like plastic, metals, fiberglass and glass. Fortunately, you don’t need a specialized meter for the type of material you’re measuring. There are all-in-one gauges, like the BENETECH GM100, that are programmed to measure a range of materials.

One common application of ultrasonic gauges is for measuring the thickness of metals. For instance, construction professionals often consult metal thickness charts, which provide given thicknesses for different types of metal. Gauge 14 sheet metal or aluminum, for example, has a specific thickness.

Why is material thickness important? For one, different ultrasonic gauges are optimized for different types of materials. For instance, thin materials, like Gauge 16 sheet metal, require ultrasonic gauges that produce higher frequencies, while thicker materials require ultrasonic gauges that can produce lower frequencies.

Advantages of Ultrasonic Thickness Gauges

Ultrasonic thickness gauges provide several advantages over other precision measurement tools like calipers and micrometers.

1. Ultrasonic gauges provide non-destructive measurement; they only require access to one side of a material to provide an accurate measurement. That means they can fit into more places, and don’t require cutting out material to gain access.

2. Ultrasonic gauges are extremely precise. Depending on the type of gauge you’re using, you can determine the thickness of a material to within fractions of a millimeter up to several hundred millimeters. Clearly, they’re extremely versatile and the latest gauges are all very accurate.

3. Finally, ultrasonic gauges are easier than ever to use. For instance, the BENETECH GM130 provides auto calibration. These devices can be easily programmed to measure different types of materials, so that switch between measurement quickly. And they’re easy to use; operators point and shoot, and a measurement is provided within seconds.

Medical Industry Update: Introducing the World’s Smallest Hearing Aid

Hearing aids have come a long way since they were first developed following World War II. Then, hearing aids were designed to help returning veterans who were experiencing hearing loss due to combat.

Now, the technology is changing rapidly, said Dr. Ross Tonini, of the Baylor College of Medicine, in an interview with the BCM Momemtum.

First, the majority are now all-digital, providing better sound quality than analog versions. Plus, many of today’s hearing aids are web-connected, acting first as hearing aids, but thanks to Bluetooth, they’re now doing double duty as music players, cellphone receivers and more. The design has changed too.

Hearing aids are now smaller and more discrete. In fact, a majority of In-The-Ear hearing aids available on the market are silicon-based and blend in more naturally than ever. For instance, the Loud N Clear “In The Ear” Rechargeable Hearing Aid ZD-900B features a sleek, behind-the-ear design, that fits seamlessly in the ear.

It’s clear the technology has changed – but a new hearing aid that’s still in development should be a game-changer. A Serbian professor, who has worn hearing aids her entire life, decided to make a completely invisible hearing aid.

Enter the Nanoplug.  Along with an industrial designer, Nevena Zivic came up with the Nanoplug – which fits inside the ear canal and is smaller than a coffee bean. The project has caught on too. Leading news websites like CNET and the International Business Times hailed the project a masterpiece.

And it appears many people are interested as well. An Indiegogo fundraising campaign had reached well beyond its goal of $80,000. Currently, more than a thousand donors have helped raise over $293,000.

The idea is also that the hearing aid will be economical, relatively speaking. At $400, it’s still light years ahead of most budget hearing aids. For instance, our behind-the-ear and ear-plug hearing aids start at just over $11.00. But that might change, as the cost of technology lowers. We’ll see, whenever it hits the market.

Top 10 Reasons to Choose IP Security Cameras

The digital vs. analog debate isn’t just taking place in consumer electronics; it’s playing out in the security industry as well. Over the last decade, many security providers and businesses have embraced all-digital IP security cameras, and have turned to upgrading existing closed-circuit systems.

IP security cameras, or Internet Protocol cameras, are web-connected cameras that transmit video and audio wirelessly. These WiFi-enabled cameras differ from wired, analog systems, in that they don’t require connection directly to a storage hard drive. Instead, they connect wirelessly to hard-drives, connected memory systems, cloud-based servers or stream video on the web.

For businesses, IP cameras present some serious benefits over their analog predecessors, including better image quality and remote accessibility. And these benefits will only continue to get better as the technology improves. Here are 10 reasons why you should consider IP cameras:

  1. Easy and Affordable Setup:

    Many of today’s IP security cameras are plug-and-play, out-of-box solutions, like the SEAHAWK 605-24WX, a WiFi-enabled dome camera. That means they can be deployed in a matter of minutes, and they don’t require deep technical expertise for set-up. Plus, IP security camera installation doesn’t require extensive infrastructure, drastically cutting start-up costs.

  2. Simplified Video Management:

    Since the data from IP cameras is stored remotely on web-connected devices, videos can be accessed from anywhere. Videos can be accessed on home computers, smartphones and tablets at any time. Plus, digital video simplifies management; videos are searchable and can be organized by date, camera location and time. Management has come a long way from the rewinding that’s necessary with VHS security systems.

  3. Improved Image Quality:

    Today’s fixed and PTZ (pan, tilt, zoom) security cameras record video in full HD, and no image data is lost when they’re transferred to storage. Plus, the technology enables clearer, higher resolution images, making it easier to distinguish objects, faces and animals. IP cameras are also much better at recording high-speed images, which is useful for both indoor and outdoor security.

  4. Automated, Smarter Cameras:

    Another added benefit: IP cameras are “smarter” than analog cameras. They can be programmed to detect anomalies, obstructions and other odd occurrences, and then send an alert to users via text, e-mail and more. Plus, they’re equipped with motion detection, provide analytics about videos, and can be customized to fit your security needs.

  1. Easier Scalability:

    Adding additional cameras to a web-connected system doesn’t require new recorders or additional cables. Instead, system expansion is easier and these systems are extremely flexible. That means, as your company grows, your security system easily grow with you. Plus, network-IP cameras can be integrated with other systems, like alarms, motion-detection lighting systems and access control systems to provide enhanced security.

  2. Cost Effective:

    The cost of installing an IP security system has dropped greatly in recent years, and today, installs are priced competitive compared to analog systems. One reason is that analog systems require special cables and more data storage hardware. Some IP cameras are WiFi enabled, meaning they don’t require cables, and other can transmit data on a single, lower-cost cable. Plus, with cloud-connected IP cameras, there’s no need to invest in infrastructure like VHS recorders or DVR, which can add to the cost of implementing an analog system.

  3. User Friendliness:

    Both IP cameras and the networks they connect to are designed with the user in mind. That means many are plug-and-play – you can connect the camera to the web in minutes – and data management is easier for non-technical people. Newer cameras are also available with smartphone and tablet connectivity, which make them even easier to manage.

  4. Great Durability:

    Both indoor and outdoor IP cameras have come a long way in terms of durability. There are waterproof and weatherproof IP cameras available that are perfect for outdoor security, and the housing options can match any architecture, including dome cameras and bullet cameras of all colors.

  5. Remote Accessibility and Control:

    Another great feature of web security cameras: They can be controlled remotely. For instance, there are many PTZ IP cameras available that can be repositioned remotely via a smartphone, tablet or desktop. Other controls like on/off, focus and automated settings like timed pans can be set over the web.

  6. Encrypted Data Security:

    The majority of today’s IP security systems encrypt the transmitted data, adding an additional layer of security.

A Few Disadvantages of IP Security Cameras

Clearly, there are many great benefits to upgrading an existing security system or installing a new one. But there are also a few disadvantages compared to analog systems that you should consider.

  • For instance, an all-digital system requires more bandwidth on your network when the cameras are recording, which can add to networking costs. Fortunately, data transmission has come a long way, and the broadband requirements are dropping.
  • Additionally, some systems require a software license for each camera, which can be costly with larger scale projects.
  • And finally, some IP cameras must be placed within a certain distance of the network, which limits where they can be positioned and may require you to purchase additional equipment.

Can Security Cameras Lower Home Insurance Premiums?

Homeowners insurance is calculated using a few constants. For instance, your premiums are based in part on your home’s location, the cost to rebuild it, and the value of the contents of your home. Those don’t change much.

But, if you are interested in reducing your insurance premiums, there are a number of steps to take that can help reduce what you pay.

One of the biggest and easiest ways is improving home safety. According to Farmers Insurance, this is the No. 1 most effective way to reduce your premiums, and Travelers Insurance also cites home security as a way to possibly lower your premium.

So the answer is yes, home video surveillance and other security systems can lower your premiums. Even disaster-proofing, which, in turn, improves safety, can help lower your premium. The reason is simple: A more secure home can lessen the risk for burglary or home disaster, ultimately saving the insurance company money.

What Types of Home Security Reduce Insurance Premiums

There’s no right answer, as it depends on your insurance company. That’s why it’s smart to check with them first to understand what kinds of upgrades qualify for insurance deductions.

But typically, home security enhancements like surveillance cameras, alarm systems and dead bolt locks all can help. Additionally, enhancing window security, adding fire sprinklers and smoke detectors security, and joining a neighborhood watch program can also contribute to lower premiums.

How much will you save? It depends on your insurance company, but the majority of insurers do provide incentives for home security upgrades. According to the Insurance Information Institute, adding all or some of these systems can help cut your rates by 5 to 20 percent.

There’s a simple reason why security enhancements can save so much. According to U.S. property crime data, homes without security systems are 3 times more likely to be burglarized. And considering the typical burglar breaks into a home in 60 seconds, it’s helpful to take steps to prevent them before they act. Home security cameras, for instance, are an extremely effective deterrent. Because most homes are burglarized during the day, visible video surveillance cameras can turn away criminals before they act.

Therefore, a home security camera system, in tandem with an audible alarm and quality dead-bolt locks will better deter criminals.

6 Safety Tips for Non-Sparking Tools

Non-sparking tools are commonly made from non-ferrous metals like brass, bronze, or alloys, like aluminum-bronze. In turn, these tools greatly reduce sparks when they’re used properly, which can reduce the risk of fire or explosion in hazardous work environments.

Standard hand tools, on the other hand, are commonly made of steel alloys. When struck or ground against surfaces, steel tools tend to create sparks, which have the potential to ignite flammable vapors, dusts, solvents or liquids. In these hazardous environments, non-sparking tools add another layer of safety and can help prevent accidents. The key, though, is following the manufacturer’s recommended use guidelines and maintaining your non-sparking tools properly. Here are some safety tips for non-sparking tools:

1. Keep Your Non-Sparking Tools Clean

To maximize the non-sparking property, your tools must be free of contaminants, like iron or steel residue. When these substances are present on the heads of a non-sparking wrench, for instance, the tool is more likely to generate sparks. To prevent this, follow the regular, manufacturer-recommended cleaning schedule.

2. Avoid Using Copper-Based Non-Sparking Tools with Acetylene

Tools that are made mostly of copper, like an aluminum-bronze hammer or wrench, should not be used in direct contact with acetylene, because there’s a risk for the formation of explosive acetylide. This is particularly true in damp environments. In these situations, potential explosions aren’t caused by sparking; instead, they are caused by the reaction between copper and acetylene.

3. Proper Maintenance

Non-sparking tools are made with softer metals compared to standard steel tools. This can cause them to wear more quickly, and in turn, non-sparking tools require regular maintenance. Therefore, to maximize their capacity, follow the manufacturer instructions for regular face- and head-resurfacing.

4. Use Proper Ventilation

Non-sparking tools are commonly used in environments where flammable vapors and dusts are present. The use of a local or mechanical ventilation system can help diminish the presence of these contaminants, and subsequently, reduce the risk for fire or explosion from sparking surfaces.

5. Understand Your Environment

Although non-sparking tools can reduce fire and explosive risk, it’s still important to monitor the work environment to ensure an explosive environment doesn’t develop. A gas detector or infrared thermometer, for example, can help you quickly gauge potential hazards at the work site.

6. Know Your Non-Sparking Tools Rating

The material your tool is made from is designed to be used safely with particular elements. For instance, aluminum-bronze non-sparking tools aren’t safe for use around hydrogen, gas of water, or acetylene. Copper-beryllium hammers and other tools, on the other hand, can be used in the majority of environments, but you should use caution around acetylene. Following the manufacturer’s guidelines use will help you avoid using your non-sparking tool in the wrong environment.
