For the position sensor, the ELPM series linear poten- tiometer with the maximum stroke of 150 mm was used. This potentiometer has a ruggedised IP67 sealed aluminum housing, a elastomer damped wiper for shock and vibration durability, and self-aligning pivot bearing mountings. For the force sensor, the in-line sensor was used produced by Futek Advanced sensor technology, INC., model - LCM 200. The sensor is able to measure both tension and compression forces. It weighs only 17 g and the natural frequency of the sensor is 26.8 kHz. This sensor is used together with a strain gauge amplifier characterizes with a bandwidth of 10 kHz.
