DM500 Loop Powered Indicator

Brand: Status Instruments

The DM500 is a loop-powered process Indicator designed to be connected in series with a (4 to 20) mA current loop and to display digitally, in engineering units the process variable represented by the current flowing.

Coarse and fine potentiometers are provided for both span and zero adjustment. The 3 ½ digit LCD display requires a very low loop drop, only 1 volt.

The display is housed in a 100 mm diameter stainless steel dial gauge housing.

Style F and G housing are deeper to accommodate any suitable in-head (4 to 20) mA transmitter.
