Q+A from the Inductosense/SN Integrity Webinar

 

What is maximum temperature the sensor can be attached to?

The working temperature range for the sensor is -40℃ to +150℃. It survives short term exposure up to 180℃.

What is the accuracy of the reading? What is the minimum wall thickness that can be measured?

The ultrasonic reading has an accuracy of <0.05 mm (0.002 inch). The minimum wall thickness that can be measured is 2 mm (0.08 inch).

Do sensors have a unique number for identification?

Yes, each sensor is installed with a unique RFID tag to ensure traceability of the data. The RFID tag is activated and logged when the WAND measurement is taken.

What lengths of ECHO do you supply?

Our standard ECHO solutions are 45 cm and 100 cm. We have developed ECHOs with lengths up to 8m and would be happy to discuss how best to fulfil your requirements for this.

Are WANDs locked to a set of sensors?  Or can multiple wands be used?

The WANDs can be used with any sensors. If there are multiple WANDs across multiple sites, any of them can be used to take readings from the sensors.

Is the instrument intrinsically safe or do you need to raise a hot work permit?

The sensors themselves are ATEX/IECEx approved. The WAND data collector itself must have a hot work permit to be used in dangerous environments.

What is the size of the measured area where the UT reading is taken? How does this compare to the sensor diameter? 

The reading is taken from the active element, which measures 5 mm by 15 mm, this compares with the sensor diameter of 55 mm.

What is the minimum diameter of piping the sensors can be fitted to?

Pipes with curvatures down to 2-inch diameter can be monitored with the sensors. The monitoring of pipe elbows can be done on curvatures of 3-inch and above.

Does the sensor work with different acoustic velocities?

Yes, the acoustic velocity related to the material being monitored is added to the RFID information when the sensor is installed.

What surface preparation needs to be done for the adhesive? Is a wire brush sufficient?

In most cases, a wire brush will be sufficient surface preparation for the main area, with a small amount of preparation needed to a higher grade, this can be done by hand sanding. For more information: we require the surface to be prepared to ISO8501-St2 for an area of 50 mm diameter, with a small area of 15 mm diameter prepared to ISO8501-St3. In locations severe external corrosion, a Bristle Blaster or electric sanding disc can be used to speed up the process, if appropriate.

 

How durable is the sensor? e.g. with respect to UV damage

Once installed, our sensors are coated with a patch to isolate the sensor itself from the external environment (for example UV and moisture). This ensures durability of the system, with the sensor expected to last the lifetime of the asset.

 

Can the sensor use a second wall echo for the measurement and avoid coating thickness?

Due to the focus on the durability of the sensors, we require the surface to be prepared to a bare metal finish. In this case the coating must be removed.
