TO Housing OEM Pressure Sensors Model 357S
Description
Based on piezoresistive effect, BCM 357S TO housing OEM pressure sensors for PCB mounting are silicon pressure sensors, by a BCM sensor die (model SE103 or SE105) all in one integrated encapsulation with TO pressure inlet(s).
The sensor is made with temperature compensation by means of laser rimmed technologies, feature reliable performance and high accuracy, TO housing makes the 357S sensor suitable for PCB mounting applications, widely used in industrial controls, pressure calibrating instruments, biomedical instruments, auto electronics etc.
Model 357S OEM pressure sensor can be used to measure pressure ranges of 0~0.73 psi to 0~10 bar in gauge absolute or differential pressure configuration, and posses high accuracy up to 0.1%fso (fso=full scale output) in operating temerature ranges of -40~+125°C. The 357S pressure sensor can be excited either constant current of 1~1.5 mA, or constant voltage of 5~10 V on requesdt.
Features:
1. TO housing suitable for PCB mounting applications for non corrosive gas or fluid medium
2. Temperature compensation by laser trimming
3. Optinal accuracy for gauge, absolute (ranges>15 psi) and differencial pressure
4. Standard 3/16” port, low profile
