AC11 low pressure oil filled sensor series are based on piezoresistive silicon pressure sensors packaged in a 316L stainless steel housing. The sensing package utilizes silicon oil to transfer pressure from the 316L diaphragm to the sensing element.
The oil filled sensor is designed for o-ring mounting for the applications where compatibility with corrosive media is required. Each sensor was strictly temperature compensated for both zero and span.
The low pressure oil filled sensor was designed by using backside sturucture(without header) to minimize the oil filled volume, The purpose is to achieve high stability and lower the temperature shift.
* Low pressure with high stability
* Wide operable temperature range -40-125℃
* Compatible with corrosive media
* Standard mounting size
* Process control
* Fresh and waste water measurements
* Medical instruments
* Pressure transmitters
Remark: Ribbon Cable or Connect Pins are optional for all models
