Plug-and-Play, Distance Compensated, Non-Contact and Easy to Apply
Torque can be measured instantly by placing a thumb-sized probe onto the Test Object (like a gearbox shaft) and then simply pushing the initialisation button.
The Active-3 Torque Sensor is ideal for industrial, motorsport, and power-tool applications. Active-3 boasts a high signal resolution (14 bits), high system internal signal bandwidth (10,000 samples per second), and impressive measurement linearity (0.2% of Full Scale).
Insensitive to air gap changes

Sensing Module Design
TAM offers standard and custom specific Sensing Module designs to meet a wide range of application specific requirements. The Sensing Module is connected to the Sensor Electronics by a cable that can be up to 2.5 meters long. Inside the Sensing Module is the round shaped Sensing Element with a minimum diameter of 20 mm. The face of the Sensing Module is concave; therefore it sits closer to the surface of the Test-Object (like a gearbox shaft). The Sensing Module does nottouch the Test-Object and can be placed up to 3 mm away from it (maximum air-gap is 3 mm).
The “zero” to +5 Volt analogue signal output of the A3 Sensor System provides highly linear and low hysteresis Torque measurements.
