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.
