CCT pressure/temperature sensor
For air-conditioning systems with heat pumps
The CCT pressure temperature sensor is often used in heat pumps for climate control systems and in thermal management (battery), particularly in vehicles with alternative drives. The specially developed thermo receptors permit a fast response time in flowing media and guarantee the high accuracy of the temperature measurings.
The design excels due to its compact size and minimal weight, which makes it easy to integrate and ideal for lightweight systems. The specific evaluation electronics make the pressure and temperature signal available via a digital single wire interface (LIN) and auto adressing.
High quantities can be realised at an affordable price thanks to fully automated production.
