Strain link sensors picks up surface-strain between the 2 mounting locations.
The strain occuring between the mounting areas is mechanically amplified inside of the sensor.
The integrated AC amplifier supplies a signal that needs no reset -> the signal drops even if the load remains present.
Ideal for very fast cycles where a reset between the cycles is not possible.
The controler only needs to measure the output signal periodically.
Thanks to the rugged design, this sensors are used in heavy industrial environment.
