The MS5837 are digital OEM sensors that measure the absolute pressure with high resolution. They are compensated and output the measured values as digital output signals via an I²C interface.
The reflowable sensors are designed for the pressure range of 300 – 1200 mbar (MS5837-02BA03) and 0 – 30 bar (MS5837-30BA) and are media-protected with a gel coating. In addition to the pressure, they measure the temperature from -40 to 85 ° C.
The MS5837 pressure sensors consist of a piezoresistive pressure cell and an amplifier A/D-interface-IC, housed in a QFN package (3.3 x 3.3 x 2.75 mm³). The metal top protects the electronic components and facilitates O-ring mounting. The sensor converts the measured pressure- and temperature-dependent signal of the measuring cell into a 24-bit data word. In addition, 6 individual coefficients are stored in the sensor, which allow the highly accurate software correction for the pressure and temperature measurement by an external microprocessor. The I²C interface is used for serial communication with the microprocessor.
The sensors are intended for applications with a digital system environment. Since there is already a processor at system level, this can be used to easily calculate the current pressure and temperature values.
