High-Quality Wall Thickness Measuring Equipment  

It’s always been necessary to take wall thickness measurements to check for signs of corrosion or damage that could indicate that a part needs repairing or replacing. In the past, such methods usually involved dismantling the test piece, which resulted in higher labour and scrap costs. In addition, the process was time-consuming and would often leave a piece of equipment out of action for extended periods. 

Nowadays, the process is simpler and cheaper, thanks to ultrasonic wall thickness measurement gauges. Companies can use these devices to inspect and quickly identify corrosion, erosion, or damage early before the situation escalates into equipment malfunctions, breakdowns, and structural issues. 

At Cygnus Instruments, we’ve spent the last 39 years designing and developing ultrasonic wall thickness measurement gauges for a wide array of applications. These applications range from undersea use to testing in explosive environments. All our devices feature market-leading technologies and come with our Multiple-Echo testing mode as standard. 

Multiple-Echo mode works using a single-crystal probe, providing accurate, error-checked thickness measurements that ignore coatings and corrosion. It does this by transmitting three separate sound pulses rather than one. When all three pulses return, the device records the interval between each pulse to calculate the material thickness. 

The beauty of this mode is that intervals between the three consecutive echoes must be equal for the reading to be counted. This makes this mode a lot more accurate than Single- or Echo-Echo modes. 

In addition, our ultrasonic wall thickness measurement gauges also sport a robust and intuitive onboard operating system that enables users to record and interpret thickness readings quickly, even while on the go. 

As stated, we’ve engineered devices to suit a wide range of applications, and thanks to our global presence, these devices can be acquired by anyone in the world. 

As a company, we know that our devices will exceed our customers’ expectations and that you’ll find no better alternatives anywhere else. Every ultrasonic thickness gauge that we design and build is the product of our extensive experience in the marine inspection industry and thousands of hours of research and development. 

Today, we proudly supply a wide range of industries with ISO-9001 certified ultrasonic thickness gauges, including: 

  • Civil Engineering 
  • General Industry 
  • Hazardous Environments 
  • Offshore 
  • Oil And Gas Pipelines 
  • Plant Maintenance 
  • Rope Access Surveys 
  • Shipping 
  • Storage Tanks 
  • Subsea Inspections 

This is by no means an exhaustive list as we cater to any industry where wall thickness gauges are commonly used. If you’d like to find out more, just give our team a call today. 

Our Range of Wall Thickness Measuring Equipment  

Here at Cygnus Instruments, we recognise that no two customers will necessarily have the same requirements. In addition, there exist different applications for thickness gauges, so it’s important to cover all the bases. To that end, we supply a range of products, including: 

The Cygnus 1 device is especially noteworthy if you’re looking for an ATEX-certified device. Such devices are certified as not producing sufficient thermal or electrical energy to trigger an explosion. This means that these devices can be used in any environment where an explosive atmospheric mixture is present, even in its most easily ignitable state. 

And in addition to the devices listed, we also supply ‘+’ variants of the Cygnus 2 and 4. These versions also come with Single- and Echo-Echo testing modes, making them useful for customers who require all three testing modes. 

Other Devices We Offer  

Besides designing and building the best ultrasonic wall thickness gauges, we also cater to other requirements. For example, our product range also includes ultrasonic probes necessary for wall thickness meters to take accurate measurements. 

And if you’re looking to detect leaks without resorting to pumping an entire cargo hold full of water, our hatch cover detectors are the right solution. These devices take the time and hassle out of leak inspection, simplifying operations and making things go a lot faster. 

Hatch Cover Detectors  

It’s common in certain industries to carry out regular inspections on hatches and door seals to ensure that no water is making its way anywhere it shouldn’t. However, this is often easier said than done, as hairline cracks and pinpoint holes can let in water but be almost impossible to spot visually. 

Historically, leaks were detected by a process known as hose testing, which involved pumping the cargo hold full of water. The obvious downside is that the cargo hold must be emptied before this can happen, and the testing can only be carried out while in port. In addition, the test cannot be performed in sub-zero conditions, and the deck scupper drains must be open, leading to pollutants leaking out into the water. 

If that wasn’t bad enough, hose testing must be performed by at least two people and cannot detect leaks as well on the cross-joint or side-joint. 

The solution to this problem is the Cygnus Hatch Sure which utilises ultrasonic technology to inspect cargo hatch covers and door seals quickly and with pinpoint precision. Unlike hose testing, hatch cover detectors can be used at sea while the cargo hold is full, even in sub-zero temperatures. 

The device employs the use of 19 ultrasound emitters that transmit sound waves at 40KHz. The emitters are arranged in such a way that produces an omnidirectional sound field. This ensures even distribution throughout the cargo hold, meaning that leaks even along the side- or cross-joint can be detected with complete accuracy. 

Sound energy passes through gaps in the enclosed space. This sound then returns to the device and is caught by the ‘receiver’ part of the device. The return signal is analysed, and information is provided that indicates whether a leak is present or not. The Cygnus Hatch Sure operates with such precision that even hairline cracks and pinpoint holes can be detected. The deck scuppers can also remain active throughout, so there are no leaking pollutants. 

Ultrasonic Probes

Ultrasonic wall thickness measurement gauges interpret and display data indicating corrosion, erosion, or damage. However, for this process to happen, an ultrasonic thickness gauge must be equipped with the right probe (transducer). Attaching the wrong probe will provide false readings and could lead to you making a costly mistake. 

At Cygnus Instruments, we supply three different probe types: 

  • Single-Crystal 
  • Twin-Crystal 
  • High-Temperature 

Single-crystal probes work with all our ultrasonic thickness measurement gauges. That’s because all our gauges come with Multiple-Echo mode as standard, which single-crystal probes are designed for. In addition, these probes can take measurements through coatings up to 3mm thick or 20mm when ‘Deep Coat’ mode is enabled. 

All our single-crystal probes feature a soft face with a replaceable wear membrane and are manufactured from stainless steel. 

Twin-crystal probes are intended to work with devices that employ Single- and Echo-Echo testing modes. As such, if you plan on purchasing a ‘+’ or ‘PRO’ device for these testing modes, you should make sure to add twin-crystal probes to the list. Using these probes, you can inspect for signs of heavy back-wall pitting, corrosion, erosion, and damage. 

Lastly, if you’re looking to inspect equipment that’s still switched on and in use, you’ll need to invest in high-temperature probes. These probes work with all our ultrasonic wall thickness measurement gauges and are intended for such purposes.
