Outline Drawing

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.
