Air Pressure Sensor (APS)

For air pressure applications

The Air Pressure Sensor was derived from our Climate Control Pressure Transmitter (CCT). This hermetically sealed and robust aluminum housing makes this sensor a cost-effective solution. The APS is compatible with a wide range of media thanks to its high-quality stainless steel measuring element. Its innovative evaluation electronics reliably provide highly accurate measurement data over a wide temperature range via an analog interface.

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