DM500 Loop Powered Digital Thermometer.
The DM500 is a loop powered process indicator, designed to be connected in series in a 4 to 20mA 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 measurement. 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.
Having no exposed glass or mercury in its construction the DM500 is ideally suited to food and pharmaceutical applications.
