12. Sensor Installation
The TankRadar REX system includes various integrated equipment such
as temperature sensors and Water Level Sensors.
12.1 Temperature Sensors
Up to six temperature sensors can be connected to a REX Radar
Transmitter Gauge (RTG). By using a Data Acquisition Unit (DAU) a
maximum of 14 temperature sensors can be used in a tank.
Figure 12-1. Up to six temperature elements can be connected
to a REX gauge.
The Multiple Spot Thermometer (MST) measures the temperature with a
number of Pt 100 elements placed at different heights to provide a
temperature profile and an average temperature. The spot elements are
placed in a flexible gas tight tube made of stainless steel which can be
anchored to the tank bottom.
