With its new
EMD-technology this sensor can measure static and
dynamic torques from non-rotation up to permanent high
speed.
The
reliability and, above all, the very low price opens up
new possibilities next to the present applications for
torque measurement sensors.

| Description |
 |
A new,
patented technology (EMD-technology) is used to create
the electrical voltage from the applied torque.
The nickeliferous steel shaft is impregnated with a
permanent magnetic pattern.Torque changes this pattern
as well as the magnetic field. As a result, the sensor
delivers a torquedepending but less speed-depending
measurement signal for the evaluation by
EMD-electronic of the stator.
The function derives only from a magnetization of the
shaft (no strain gauges, no wiring).
An ASIC for signal extension gives the user a
torque-proportional electrical voltage.
