The Remote Display Unit (RDU 40) is a robust display unit for outdoor use in hazardous areas. If the number of temperature elements per tank is 6 or less, the RDU 40 is the most cost effective solution for field display. In this case the temperature elements can be connected directly to the TankRadar Gauge (RTG) without using a Data Acquisition Unit (DAU).
The display functions are software controlled by the connected gauge. It is easy to work with via the 4-key display keyboard. Each screen view can display 7 text lines with 16 characters per line.
It displays calculated data such as level, average temperature, volume, signal strength etc. Data can be displayed in lists or as single values, with a choice for the operator to have a user defined view.
The RDU 40 is connected by a 3-wire cable up to 100 m (330 ft) from the RTG. Up to two units can be connected to the same TankRadar Rex gauge.
