Yarn sensors use Hall Effect for signal generation. The tension of the yarn presses down a bending beam which is equipped with a magnet at its end. The moving magnet causes a change of the magnetic field in the stationary hall element, which depends on the load. By means of an internal amplifier the output signal is amplified to 0…10 V.
The Yarn Tension Sensor is very robust. The used Hall technology makes the sensor very long-term stabile and independent from environmental influences. A Built-in overload stop protects the sensor from overload. With their compact design sensors can be placed very close for parallel yarns.
