Piher sensing systems - custom potentiometers and position sensors

Actuator position sensor manufacturer.

The industrial and automotive markets demand sensors (variable resistors) for the actuators that move the air distribution flaps in HVACR Systems.
The flap actuator (motor, damper) moves the flap to control wich way the air goes where  a sensor feedbacks the position of the flap (closed-loop).

Main requirements for HVAC sensors:
- Low hysteresis.
- Good accuracy (linearity of 3% or better).
- Low price for high quantities.
- Quality and flexibility.
- Long life.
