SM9D SM9G uncompensated relative / differential pressure sensor by AMSYS

SM9D/G uncompensated relative / differential pressure sensor

The SM9D and SM9G are differential and relative pressure sensors that are neither compensated nor amplified. They have the properties of the measuring cell and output the differential bridge voltage in mV.

The uncompensated SM9X are offered in a standard SOIC-16 package with two vertical or horizontal pressure ports and one horizontal pressure port for SMD mounting. The output signal is a pressure-proportional mV signal. The SM9X are reflow-capable and suitable for automated mounting on PCB.

The sensors are not recommended for new designs.

Variants of the SM9D/SM9G

The sensor is available as a differential pressure sensor SM9D 0.15 / 0.6 / 1.5 psi or as a relative sensor SM9G 0.15 / 0.6 / 1.5 psi.
