ANALOGUE OUTPUT
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 102 mm H
2
O FS and the output is ratiometric to
the power supply voltage. Other pressure ranges on request ( 0.3 – 100
PSI).
