I2C, SPI Pressure Sensor and Transducer

I2C, SPI Pressure Sensor Introduction:

I2C, SPI pressure sensor and transducer is based on piezoresistive silicon pressure sensors packaged in a 316L stainless steel housing. The pressure sensor supports I2C and SPI interface protocols, may come in a 3.3 or 5.0Vdc supply voltage.

The sensing package utilizes silicon oil to transfer pressure from the 316L diaphragm to the sensing element. I2C SPI pressure sensor is designed for o-ring mounting. The pressure transducer is suitable for applications where compatibility with corrosive media is required.

A custom ASIC is used for temperature compensation, offset correction, and provides a digital output of 10~90% or 5~95%. The circuit exceeds the latest heavy industrial CE requirements.
