SPD102SAhyb Pressure Sensor
SPECIAL LOW PRESSURE RANGE DIFFERENTIAL SENSOR WITH ANALOGUE OUTPUT (SINGLE VERSION)
This Smartec differential pressure sensor has an amplified analogue output. The sensor is compensated for offset, sensitivity, temperature drift and nonlinearity. The sensor has a range of 0.15 PSI FS and the output is ratiometric to the power supply voltage. Other pressure ranges on request ( 0.3 – 100 PSI). When no pressure is applied output Voltage is minimal; single type.
