5.The Remote Display Unit RDU40

The Remote Display Unit 40 (RDU 40) is a robust display unit for outdoor use in hazardous areas. If there are less than six temperature elements per tank, 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). The display functions are software controlled by the connected TankRadar gauge.

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 one TankRadar Rex gauge. It displays calculated data, such as level, average temperature, volume, signal strength, etc. The data can be displayed in lists or as single values. The operator can set up a user-defined window where the most useful information is presented. This window will be shown as the default view. The RDU 40 can view up to six spot temperature elements connected to a TankRadar Rex gauge.

See chapter 11.5.11 for more information on how to connect the RDU40 to the REX transmitter. See also the Display Unit RDU40 User´s Guide for instructions on how to use the RDU40.
