Compact and Durable Digital Output Pressure Sensor for Long-Term Pressure Monitoring

CPS135B is based on SIP (System in Package) solution, consisting of a bridge silicon piezoresistive chip and calibrated with 24 bit numbers
Composed of processing output chips, providing high-resolution and highly accurate pressure measurement. After full range pressure calibration and temperature compensation
CPS135B can provide customers with very simple digital outputs. The digital to analog conversion unit is calibrated by an internal logic,
By directly accessing the I2C interface, the measurement results of pressure and temperature can be read very accurately. No need for additional separate downloads
Internal logic correction coefficients and access to the main processor to perform complex compensation operations.
