DM700 Loop Powered Digital Indicator.
The DM700 is a Loop Powered Indicator which incorporates a high efficiency LED display. Designed for use with our SCH4 heads, the units are sealed to IP67. ATEX versions are available for use in hazardous areas using the SCH4 head.
The unit is microprocessor based and the displayed process range is achieved by means of three push button switches located on the underside of the module following a simple menu structure.
The product can be temperature probe mounted and is suitable for our PPL3, PPL4, PPL5, PPL6 and PPL8 styles or can be surface mounted. It is powered from an existing current loop so no extra wiring is required. Of course the indicator can be incorporated into any measurement loop that is utilising a 4-20mA signal such as pressure, level, flow or humidity transmitters.
A similar unit is available which incorporates a 4-20mA transmitter, SEM710, which is ideal for fitting to temperature probes that do not have a temperature transmitter.
