Product Description
- 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.
Caution
1. Please do not touch the diaphragm by finger and other hard objects, or it may be damaged.
2. The sensor filled with olive oil is for sanitary application. It can't work when the temperature is below 0ºC, because the olive oil will freeze below 0ºC.
