BS12D Piezoresistive OEM Differential Pressure Sensor
***Features
Pressure range 0~700kpa;
Constant current power supply;
316L Stainless steel;
Isolated construction to measure various media;
Differential pressure sensor.
***Introduction
BS12D piezoresistive differential pressure transducer is OEM pressure transducer applied in differential pressure measuring, typically of gases, vapor or liquids. Two high-sensitivity piezoresistive silicon pressure chips are employed inside the transducer. The stainless steel housing protects the chips against ambient influences. The measured differential pressure is transmitted onto the die through the diaphragm and filling silicon oil, finally it is converted into an electrical signal. Widely used for industrial process control and differential pressure measure fields, etc.
***Application
Industrial process control
Differential pressure measure
Gas, liquid pressure measurement
Pressure calibrator
Liquid pressure system and switch
Ventura and eddy-current flow meter
Refrigeration equipment and air conditioner

***Order Note
1. It is recommended that the sensor should be installed as Suspended Mode to avoid face tight press and avoid affecting sensor stability.
2. Please pay attention to protect the diaphragm to prevent any damage or bad performance.
3. If the working temperature of Viton rubber exceeds the temperature of the rubber specification or be applied in critical environment, please contact us.
4. The material of measuring medium should be compatible with the stainless steel. If it is corrosive, pls specify its material in detail.
5. All specifications are subject to change. Contact Gaohua for specifications and engineering drawings that are critical to your application. Drawings contained in this document are for reference only.
