SM6841 absolute pressure sensor by AMSYS

SM6841 absolute pressure sensor

The SM6841 is not recommended for new designs.

The SM6841 are absolute pressure sensors that are neither compensated nor amplified. They have the properties of a measuring cell and output the differential bridge voltage in mV.

The absolute pressure sensors are offered in a SOIC-8 housing (4 x 5 x 3 mm3) for manifold mounting and are therefore suitable for reflow mounting. They are especially recommended for cost-sensitive large-scale productions.
The SM6841 sensors are suitable for applications where the user wants to use his own signal processing and has the ability to self-calibrate his sensor depending on the accuracy requirements.

Advantages of the non-balanced sensor are the wide working temperature range, the high resolution and the possibility of real-time measurement.

Variants of the SM6841

The sensors are available as absolute pressure sensors for the 0-30 psi or 0-100 psi ranges.
