Ultrasonic Thickness Gauge

What is an Ultrasonic Thickness Gauge?

Ultrasonic thickness gauges are devices used in the field of industrial ultrasonic testing and inspection. They allow for non-destructive measurements to be taken of the local thickness of a solid surface, e.g., a pipe wall). Said surfaces are usually metallic. Ultrasonic thickness gauges use probes to transmit a sound pulse through a test piece. The sound then reflects back from the inside surface or far wall and is received by the probe.

The ultrasonic thickness gauge then measures the time it took for the sound pulse to return, calculating the thickness of the test piece. Employing ultrasonic thickness gauges and probes allows for the measurement of corrosion, erosion, or damage to be detected quickly. As such, these devices are commonly used to inspect structures and components to determine if repairs or replacements are required.

While many other ultrasonic thickness gauges utilize Single-Echo and Echo-Echo modes, ours come with Multiple-Echo mode as standard. Multiple-Echo mode generates three pulses rather than a single pulse. The time intervals between each pulse are measured, providing a greater degree of accuracy during testing and inspection.

Note that if you require Single-Echo or Echo-Echo modes, these are available on our ‘+’ devices.

Advantages of Using an Ultrasonic Thickness Gauge

If you’ve never used ultrasonic thickness gauges before, maybe you’ve been utilizing more traditional forms of testing and inspection, you might be unaware of the benefits. Ultrasonic thickness gauges are an incredible innovation that has drastically improved the field of testing and inspection and the way wall thickness measurements are taken. Benefits of ultrasonic thickness gauges include:

  • Entirely Non-Destructive – No Need to Take Anything Apart
  • Quick and Simple to Use
  • Highly Accurate Results (More So Than Traditional Methods)
  • Lightweight and Portable
  • One-Sided Measurements
  • Versatile
  • Compatible with Data Logging and Statistical Analysis Programs

Because ultrasonic thickness gauges allow for entirely non-destructive measurements to be taken, there’s no need to cut or section off parts, saving scrap and labor costs. That’s because of the one-sided nature of how ultrasonic thickness gauges take measurements – you don’t need to have access to both sides of the test piece.

Ultrasonic thickness gauges are simple and easy to use. Only a small amount of operator interaction is needed, and you’ll receive an almost instantaneous response. In most cases, results take just seconds to arrive and are displayed on the device’s digital readout.

Because our ultrasonic thickness testing and inspection devices are lightweight and portable, they can be easily taken to any offsite location, such as oil platforms. Ultrasonic thickness gauges are highly versatile too, as they can be used to measure all common engineering materials, from metals and plastics to composites, fiberglass, and even rub.

Lastly, ultrasonic thickness gauges come with onboard storage and data transfer ports (USB or RS232) to transfer measurements to a PC for further analysis.

Surface Thickness Gauges

At Cygnus Instruments, we design and manufacture various types of ultrasonic thickness gauges, including our impressive range of surface thickness gauges. From ATEX-certified intrinsically safe ultrasonic thickness gauges to hands-free models, whatever your requirements might be, we have them covered.

Our current range of ultrasonic thickness gauges includes:

All our standard models come with Multiple-Echo mode in-built as standard. Multiple-Echo mode allows for far more accurate wall thickness measurements to be taken without having to remove protective coatings.

In addition to our standard models, we also have ‘+’ variants of our Cygnus 2 and Cygnus 4 devices. These variants feature all three testing modes (Multiple, Single, and Echo-Echo) as the latter two are useful for extreme corrosion and pitting. The Cygnus 6+ PRO comes with these modes as standard and also boasts A-Scan, B-Scan and comprehensive data logging designed for professional users.

Cygnus 2 Hands–Free

The Cygnus 2 Hands-Free is an ultrasonic thickness gauge engineered for the most unforgiving of environments. It’s small, compact, and lightweight, sports an easy-to-use keyboard, intuitive menus, and an LCD color display for quick analysis of results. The Cygnus 2 Hands-Free ultrasonic thickness gauge features an A-Scan display and comes with Multiple-Echo mode as standard, meaning it’ll work with single-crystal probes.

Please note that a ‘+’ variant is also available that can employ Single-Echo and Echo-Echo modes when used in tandem with twin-crystal probes.

With Multiple-Echo mode, the Cygnus 2 Hands-Free ultrasonic thickness gauge can take accurate through-coating measurements. Whereas the ‘+’ variant, while in Single-Echo or Echo mode, can also carry out testing and inspection for surfaces marred by extreme corrosion or back wall pitting. While in Single-Echo and Echo-Echo testing modes, MSI™ (Measurement Stability Indicator) is available.

Hands-free operation is made possible as this particular thickness gauge is wrist, waist belt, and harness mountable. The LCD multi-functional display can be rotated and is suitable for all lighting conditions. The Cygnus 2 also sports buttons integral with the TPE molding and is designed for a minimum of 100,000 depressions.

Cygnus 4 General Purpose

The Cygnus 4 General Purpose is the perfect all-around device for carrying out wall thickness measurements in a variety of environments. It comes with the Multiple-Echo mode as standard, with Single-Echo and Echo-Echo modes also supported by the ‘+’ variant. As with the Cygnus 2 Hands-Free, the Multiple-Echo mode supports through-cover measurements and provides a greater degree of accuracy as it uses multiple sound pulses.

Single-Echo and Echo-Echo modes are both highly favored, however, in situations where extreme corrosion and back wall pitting are present.

The Cygnus 4 ultrasonic thickness gauge is compact, lightweight, yet tough and robust, sporting an extremely rugged enclosure (shock and impact proof to). It also boasts environmental sealing (water and dustproof) to IP67 – US MIL STD 810G.

It’s simple to use and sports a large, bright front color LCD display. With this ultrasonic thickness gauge, users have access to the Deep Coat function, ignoring coatings up to 20mm (0.8 inches) thick. The Cygnus 4 also boasts simple, one-point calibration, with no zeroing required.

The Cygnus 4 should be used with single-crystal probes. The Cygnus 4+ can be used with single-crystal and twin-crystal probes depending on what testing mode is being employed.

Cygnus 6+ PRO

The Cygnus 6+ PRO is the only device in our range that doesn’t come in a standard variant. As such, all Cygnus 6+ ultrasonic thickness gauges sport all three testing modes and can be used with single and twin-crystal probes out of the box. The Cygnus 6+ PRO ultrasonic thickness gauge is a testing and inspection gauge built for professional users.

It comes loaded with features, such as A-Scan, B-Scan, and comprehensive data logging capabilities. When used in conjunction with Cygnus High-Temperature probes, the Cygnus 6+ PRO is capable of measuring the wall thickness of high-temperature in-service assets. You won’t even need to shut down or isolate said assets.

This makes the Cygnus 6+ PRO ultrasonic thickness gauge perfect for use in scenarios that include:

The Cygnus 6+ PRO ultrasonic thickness gauge supports temperature compensation feature for measurement of hot material. It comes with a Deep Coat function standard on all Multiple-Echo devices. One and two-point calibration are available. This ultrasonic thickness gauge supports Bluetooth™ for data transfer.

Other features include shock and impact protection, dust and water resistance (US MIL STD 810G/ IP67), intrinsically safe operation, a large front LCD display and an end-mounted LCD display with a grayscale setting for bright sunlight.

Ultrasonic Probes

When it comes to using ultrasonic thickness gauges, you must be mindful of what device and testing mode you’re using. All our devices come with Multiple-Echo mode as standard, but only select devices come with Single-Echo and Echo-Echo testing modes. These devices include our ‘+’ variants, underwater gauges, and the Cygnus 6+ PRO.

The thickness gauge itself is there to simply process incoming sound pulses and calculate wall thickness measurements. In testing and inspection applications, it’s the probes the physically send and receive the sound pulses that the device uses. Without a probe, the device won’t work, and if you use the wrong probe, the readings you receive won’t be correct.

Here at Cygnus Instruments, we understand the importance of selecting the right probes for the job. To that end, we supply three probe types – Single-Crystal, Twin-Crystal, and High-Temperature probes. Single and twin-crystal probes are detailed below.

High-temperature probes are, as the name implies, twin element ultrasonic probes engineered for high-temperature, in-service thickness measurements. They can be used on any active piece of equipment without needing to shut down or isolate the test piece first.

Single Crystal Ultrasonic Probes

Single-crystal probes are designed to work with Multiple-Echo enabled thickness gauges because they are engineered to read through and ignore coatings. Our single-crystal probes are comprised of stainless steel and come with a soft face that incorporates a replaceable wear membrane, thereby protecting the probe face.

Twin Crystal Ultrasonic Probes

Twin-crystal probes are designed to work in tandem with Single-Echo and Echo-Echo modes and are engineered to measure surfaces with heavy corrosion and back wall pitting. If no surface coatings are present, the Single-Echo mode can be used.
