Absolute pressure sensor SM5420 by AMSYS

Absolute pressure sensor SM5420

The SM5420E is not recommended for new designs.

The SM5420E is a non-amplified OEM sensor* for absolute pressure measurement in the SOIC-8 package for SMD mounting. It has the properties of a measuring cell and outputs the differential bridge voltage in mV.

The series of SM5420E sensors cover a pressure range of 2 to 7 bar and is available with nozzle or with hole. The absolute pressure sensors consist of a piezoresistive pressure measuring cell, which in the standard version is provided with a protective gel for better media compatibility.

The operating temperature range is -40 to 125 ° C. The sensors are suitable for OEM applications for which another amplifier or microcontroller is provided, which further processes the 95 mV signal. The resolution of the sensors is not limited by any A/D conversion. Specifically, the pressure sensors can be used in rapid pressure measurements e.g. in pneumatics or as a pressure switch. They are suitable for high-volume projects.

The sensors are not recommended for new designs.
