Oil pressure sensor (OPS)

For oil-pressure measurements in the transmission

Our oil pressure sensor OPS measures the oil pressure in transmissions of e. g. electric vehicles, in order to optimise the use of the engine power. It was designed to measure the absolute pressure inside the transmission housing, and is robust enough to be used with oil in the surrounding areas.

The electronics with digital output signal (SENT) transmit measurements precisely, safely and quickly. It was developed following the regulations of functional safety (ASIL / ISO 26262).
