Celesco Inclinometer Model IT9420
The model IT9420 is a rugged yet simple device which provides a 4 to 20 mA current feedback signal for incline position. The heart of the IT9420 is a magnetically-damped pendulum coupled to a conductive plastic precision potentiometer. A highly linear relationship between inclination and a 4 to 20 mA output is maintained over the full range of the IT9420.
The IT9420 is easy to use: simply attach it to the object of measurement and install two wires for the current loop.
