Accessories
The sensor can be installed with a heating element (HBHE) so as to prevent icing of the sensor at low liquid
temperatures. Using a power supply (HBPA), the switch can be connected to 90/240VAC
HBPA is installed instead of the plug which was
provided. The power supply is universal and can be
connected to 90/240 V AC.
HBHE is installed on the cylindrical part under the
plug. The female socket is installed on the sensor
and heating element supply, and the sensor is
connected to the heating element and distributed.
HBHE has a 24 V DC supply and therefore cannot be
used together with HBPA.
Power connection
HBSR can be delivered with a PNP or NPN output.
The connection depends on the selected sensor type as well as the type of controller/PLC used.
CAUTION! In case of welding work on the unit, the electronic part must be removed.
Welding work can damage the electronics. The mechanical part of the sensor must not be
installed in the pipe socket during welding
.
