Product Overview

Description


 



PC12 Flush Diaphragm Pressure Sensor


 Features


Piezoresistive silicon chip employed


Perfect long term stability


MEMS Technology


 


PC12 Pressure Sensor is a flush diaphragm sensor. A high sensitivity silicon pressure chip is employed in the transducer. The sensor is welded within the housing, and no leakage will happen. It is more reliable compared with O-ring sealing for leakage.


It can be used in sanitary industry with olive oil/M20 filling, or silicon oil filling in non-clogging application.
