The DM500 is a loop powered process indicator, designed to be connected in series in a (4 to 20) mA current loop to display digitally the process variable represented by the current flowing. It is typically used where a digital display of the process variable is required at or near the point of measurment. The circular stainless steel housing is available in a choice of depths, permitting the installation of a suitable loop-powered transmitter and is available in wall, panel and temperature probe mounted versions.
