CCT pressure/temperature sensor

For air-conditioning systems with heat pumps

The CCT pressure/temperature sensor is used in air-conditioning systems – especially in vehicles with alternative drives – as well as in heat pumps. The specially developed thermoreceptors allow a fast response time in flowing fluids and ensure a high degree of temperature accuracy.

The design stands out for its small size and minimal weight, making it easy to integrate and particularly suitable for lightweight systems. With the specific evaluation electronics, the pressure and temperature signal is made available via a digital single-wire interface (LIN).

Thanks to the fully automated assembly, large quantities can be produced cost effectively.
