Heat isolation
In case of process temperatures of more
than 200
°C an isolation on the rear of the
flange is necessary to separate the radiation
heat from the sensor electronics.
The best would be to include the sensor
isolation into the vessel isolation and isolate it
up to approx. the first pipe segment.
4.2 Measurement of liquids
Sensor on DIN-socket piece
Most of the time the mounting of radar sen-
sors is made on short DIN-socket pieces.
The instrument flange is the reference plane
of the measuring range. The antenna should
always protrude out of the flange pipe.
Mounting on short DIN-socket piece
Reference plane
When the DIN-socket piece is longer, note
that the horn antenna must protrude at least
10 mm out of the socket.
When mounting on dished end vessels the
antenna has to protrude at least 10 mm.
