Piher sensing systems - custom potentiometers and position sensors

HVACR Sensors

Driven to perfection

The HVAC sensor family  has been designed to feedback the position of  the cold/hot air flap damper in the  HVACR system (flap motor positioning). High accuracy (2% linearity) and low cost are among its main advantages.

Over 120 million-plus HVAC custom sensors, delivered for over ten years with an PPM rate below 1 are some the impressive figures achieved by Piher for motor-actuator control feeback sensing applications related to HVAC and air loop actuators.

Piher can also build custom potentiometers resistance track HVAC thermal management actuator sensors based on printing resistors onto several substrates that seamlessly adapt to any given customer specific application.
