FAQ
-
What thickness gauges and flaw detectors are compatible with Ionix ultrasonic inspection probes?
Our inspection probes are compatible with all standard ultrasonic thickness gauges and flaw detectors that can display an A-scan. The probes have dual microdot connectors as standard which can be used with any compatible cable to provide connections to your unit.
-
What is the maximum continuous operating temperature?
Ionix probes can work continuously on surface temperatures up to 350°C (662°F). Above this temperature the probe should be duty cycled in accordance with the chart.
-
What couplant should I use for high temperature measurements?
For high temperature measurements, Ionix recommends and supplies a range of Echo Ultrasonics couplants. These couplants can be purchased through the Ionix website.
-
Can I buy Ionix High Temperature Ultrasonic Transducers in my county?
All Ionix transducers are available globally either direct from Ionix or through one of our many distribution channels. Please complete our enquiry form to receive directions on how best to order in your country.
-
Can Ionix probes be used for corrosion mapping / scanning?
Yes. The HS582i, HS5122i and HS2122i probes are all excellent for scanning due to there high operating temperature and increased wear resistance. Several leading NDT scanning companies already offer attachments. They are also fitted with mounting points to allow mounting to a range of 3rd party scanning cradles. Please contact Ionix for more information on the subject including example applications.
-
What materials can be tested?
All probes provide very precise thickness measurements on many materials, including metals, plastics, glass, and ceramics. The device can also be used to measure through coatings/paint on the surface. The measurement range on these materials does alter, but ensuring the device is aligned correctly accurate measurements can be taken easily.
-
Using automatic “Zero compensation” feature on my thickness gauge?
Conventional dual transducers are often calibrated at ambient and moved to a test piece at a radically different measurement temperature which causes the ‘Zero’, or delay, to change rapidly which can give misleading results. To adjust for this, many UT thickness gauges feature an auto-Zero compensation function for dual element transducers which offer a convenient means of making quick zero compensation calibrations to get started with your thickness measurements and adapt to the dynamic changes in temperature due to calibration and measurement and frequent duty cycling to protect the transducer from damage.
HS582i is compatible with the auto zero features of many gauges including the Olympus 38DL+, Cygnus gauges, GE gauges and Sonotec gauges. For Olympus gauges, we recommend using a cable with probe identification pin to ensure the V-path is also set correctly.
Where the auto-function is not available, an alternative method is to undertake a Zero calibration using a known thickness of the measured material, as you would do if using a flaw detector or meeting the requirements of a standard in your procedure, such as ISO 16809 for ultrasonic thickness measurements. This is often referred to in your gauge user manual as Zero Calibration, or as a method for high accuracy measurements.
Pre-heating your transducer to the measurement temperature and soaking for a minute or two will mean that the calibration is also held for much longer as the temperature remains relatively constant, reducing the need for repeated zero-compensation.See our user guidance above for more information.
