WAND TM Sensors
Thin, embeddable, permanently installed, battery-free ultrasonic sensors
The WAND TM Sensors are designed to be permanently installed on the surface of pipework and vessels to provide reproducible thickness readings free of human-error. Each sensor comes with an RFID for traceability and automated data management.
Inductosense offers the standard TM sensor, where the measurement point is in the centre of the sensor, or alternatively the offset TM sensor, where the measurement point is offset to the side for monitoring in places such as next to welds.
Technical Specifications
The TM Sensor comes in several configurations. Inductosense will recommend a design depending on the particular set of conditions such as temperature, material wall thickness, diameter, and curvature of the material.

* Specifications based on flat plate measurements at room temperature, may vary under operating conditions.
** For a straight pipe. The geometry affects the minimum diameter.
*** Above 90˚C / 194˚F, the minimum thickness that can be characterised by the sensor will increase. Please contact us for more details.
+ A sensor with the following specification is available on request:
- Minimum thickness of 2mm / Maximum thickness of up to 20mm / Maximum operating temperature of up to 110°C / 230°F
