ESCP-BMS1 is a series of board mountable capacitive pressure sensors targeting a variety of markets requiring high resolution and accuracy for absolute, gauge, or differential pressure measurements. These sensors have excellent resolution with an analog (0-3.3V), PWM, SPI, or I2C interface. The output is fully calibrated and temperature compensated. The total error including repeatability, hysteresis, non-linearity, thermal offset, and calibration error between 0°C and 60°C is better than 0.25% FS. 

Different power modes are available enabling low power operation while the output rate and conversion speed are programmable allowing the end-user to customize and optimize performance. The sensor can be configured to provide both high accuracy 32-bit pressure and temperature outputs.
