WAND TM Sensors
Thin, embeddable, permanently installed, battery-free ultrasonic sensors
The WAND TM Sensors are designed to be permanently installed on the surfaces 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.
ÃÛÌÒ´«Ã½ offers the standard TM sensor, where the measurement point is in the centre of the sensor, or 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. ÃÛÌÒ´«Ã½ will recommend a design depending on the particular set of conditions such as temperature, material wall thickness, diameter, and curvature of the material.
