The pressure sensor module is composed of a pressure sensor module and signal processing circuit packaged in a special structure ,and a set of circuit protection systems are added externally. It has the characteristics of small shape, high reliability and high precision. The linearly calibrated and temperature-compensated output of the chip is an analog signal proportional to the supply voltage and a function of the input pressure. The working pressure range is 0~1MPa for BSAG100 chip. The supply voltage is 12~30V, and the typical output is 4~20mA.
We can provide customized service for this product.
Features
- Temperature compensation range -40~125°C;
- Compact structure, compatible with ceramic size, easy to assemble;
- High reliability, low drift;
- Resistant to oil, gasoline, diesel and other oily liquids,;
- Resistant to acid or alkaline water quality and other corrosive media.
Applications
- Air compressor pressure detection;
- Pump pressure monitoring;
- Automobile oil pressure detection;
- Pressure detection in other corrosive environments.
