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 to a major automotive supplier, 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.
Piher can also build custom potentiometers resistance track HVAC sensors based on printing resistors onto several substrates that seamlessly adapt to any given customer specific application.
