The magnetic principle based, non-contact height sensor system from Torque And More measures the distance between the sensing module and a reference device. The system has a large measurement range of above 1,0m and a high signal resolution of 0,1mm.
The height sensor system consists of three building blocks: the sensor device, the reference device, and the sensor electronics. The sensing device and the sensor electronics can be placed at the same location.

Simply place the sensor module nearest to the location where the measurements should be taken from. The measurements will take place immediately after the sensor is powered-up. There is absolutely no need to attach or to glue anything onto the test shaft. No additional magnetic treatment is required.

Sensor Description:

The Active torque sensor device can measure immediately when placed to any object that has magnetic properties (easy to test by holding a permanent magnet to the test object). The Active torque sensor can be very easily applied to any shaft diameter and can also be taken off easily to be re-used at another measurement location.

Some of the outstanding and novel features of this Active sensing technology are: that the sensing performance will not age, that it can be applied to shafts / tube of any diameter, that it can measure through layers of paint and that the physical dimensions of the sensing module are very small. The
Active torque sensor can be used on stationary or moving / rotating objects and it is insensitive to humidity, splashing water, oil vapour, non-corrosive oil, dust, rust (limits apply), and any magnitude of physical upset of the test object (shocks or vibrations).


The sensor’s signal output can be either a linear voltage (from 0 Volt to +5 Volt) or of a serial digital format. Where space is critical, the sensor electronics can be placed elsewhere so that only the small-sized sensor-head needs to face the test object.
