CCT pressure sensor

For automotive air-conditioning systems

The climate-control pressure transmitter (CCT) was developed specifically for measuring the pressure of refrigerants in motor vehicles.

The hermetically sealed and robust aluminium housing makes this sensor a cost-effective solution for automotive air-conditioning systems. Thanks to its high-quality stainless-steel measuring element, the CCT is not only compatible with a wide range of fluids but is also suitable for high-pressure applications (R744). Its innovative evaluation electronics reliably deliver high-precision measurements over a wide temperature range.

Specifically tailored to the requirements of the automotive industry, the CCT also complies with the current provisions regarding EMC and ESD.
