Keller UK’s Piezoresistive OEM Pressure Transmitter 4 LC to 9 LC Series

The Piezoresistive OEM Pressure Transmitters are capable of combining a piezoresistive pressure sensor with -40…150 °C-capable signal conditioning in a single package.

Chip-In-Oil (CIO) technology is used for completely embedding the pressure transmitter into a hermetically-sealed, oil-filled housing, and can also be seamlessly integrated into the OEM product, thus saving cost and ensuring better performance.

It comprises a ratiometric analog output which helps in simplifying the task of integrators by supplying a signal output, thus avoiding the need of incorporating an expensive, absolute reference. A 5 VDC supply provides 0.5…4.5 VDC output. This helps in protecting the LC-transmitter against overvoltage and reverse polarity up to ±33 VDC.
