FWAxxxT
Displacement Sensor, Potentiometric Type

● Displacement transducers are suitable for direct, accurate measurement of displacements in automatic control and metrology.
● The pickup of the displacement is performed by using a pull rod with a universal joint. This allows for an actuation that is free from backlash and transverse forces, even in case of parallel and angular displacements of transducer and measuring direction.
● Elastomer-damped, independently resilient multi-finger noble metal sliding contact for reliable contact, even at high adjustment speed, shock or vibration.
● Long life span of 100 x 106 strokes, extraordinary linearity up to ±0.075%, pull rod running on two exact bearings, very high adjustment speed of up to 10m/s, shock and vibration
resistant.

▒ Pre-adjusted in the factory by storing the correction
values in the ALMEMO® connector.
The precise adjustment can be locally performed by the
user with final measures after the installation.
