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 compatible with a wide range of fluids. Its innovative evaluation electronics reliably deliver high-precision measurements over a wide temperature range, using LIN or analog interface.
Specifically tailored to the requirements of the automotive industry, the CCT also complies with the current provisions regarding EMC and ESD.
