Small and compact, the DM700 loop powered indicator has been designed to be completely enclosed in a clear polycarbonate cap which fits to a standard SCH4 enclosure. The unit is microprocessor based and the displayed process range is achieved by three push button switches located on the underside of the module. The product can be temperature probe mounted and is powered from an existing current loop so no extra wiring is required. An inhead temperature transmitter can be fitted in the base of the SCH4 enclosure. When installed it provides a digital readout of the process variable being measured.
