Small absolute pressure sensor with high resolution for 2 or 30 bar

AMSYS GmbH & Co. KG, Mainz, December 2021 – With the air pressure sensor MS5837, AMSYS offers two pressure range variants of a miniaturized pressure sensor for absolute pressure with high resolution. The sensors are calibrated and provide the measured values as

The reflowable air pressure sensors are designed for pressure ranges of 300–1’200 mbar (MS5837-02BA03) and 0–30 bar (MS5837-30BA) and are protected with a gel coating. In addition to the pressure, they also measure the temperature.

The sensors convert the measured pressure- and temperature-dependent signal of the measuring cell into a 24-bit data word, then stored in the EPROM. In addition, 6 individual coefficients are stored, allowing a highly accurate software correction for the pressure and temperature measurement by an external microprocessor. The I2S interface is used for serial communication with the microprocessor.

MS5837 sensors are intended for applications within a digital system. With an existing processor at system level, temperature can be easily calculated.

AMSYS offers as further variants the MS5839, with chlorine-resistant gel protection and a grove board that can be used to quickly evaluate sensors and build prototypes.
