SPD005GAsmd 5 psi Gauge Pressure Sensor with Analogue Output Description
This pressure sensor has an amplified analogue output. The sensor is compensated for offset, sensitivity, temperature drift and nonlinearity.
The sensor is available in the range from 5 to 100 psi. Other ranges on request. Available in Gauge and Absolute type. The output is ratiometric to the power supply voltage. @ 5 V power voltage the output span is 0.5 to 4.5 V. The SPD analogue series can be considered as an “analogue” successor of the SPD series.
