DEVIreg™ 850 ground and roof sensors
Installation and user manual 8
2 .2 Installing ground sensors
At this point you must have located the appropriate spots for the ground sensors and
extended the feeder cable if necessary as prescribed in section 2.1.
The sensor part and the sensor tube may now be installed in connection with the actual
construction work and connected at a later date. The following applies for all types of
installations.
a) The base below the sensor tube must be hard, e.g. a concrete plate or similar,
in order to ensure that the sensor is not pushed into the ground if e.g. a lorry
runs over it. The tube is designed to be mounted on a plate using the two screw
holes inside the tube.
b) Place the sensor tube in between the heating cables with a minimum distance
of 1 cm.
