The WNK125P is a diffusion silicon oil-filled pressure sensor specifically designed for automotive
applications. The component features a 316L welded diaphragm, eliminating the need for any O-ring seals
that could come into contact with the pressure medium, allowing it to be compatible with various liquids.
With no moving parts, it offers a longer service life. It is a high-performance, compact pressure transmitter
signal conditioning chip combined with a diffusion silicon oil-filled pressure sensor, utilizing a specialized
integrated circuit.
Its key features include corrosion resistance, wear resistance, impact resistance, and vibration
resistance. In addition to standard sensors with normal pressure ranges, its standout feature is the positive
and negative gauge pressure functionality. This pressure sensor offers high temperature stability and
accuracy, and it is primarily used in automotive, transmission, air conditioning, engine oil pressure
measurement, and other related fields.
