Installing the HBX-DX Sensor
The sensor is installed in the outlet of the evaporator, as part of the suction line. Soldering connection, fittings and pipes are
made of stainless steel. The sensor part itself must be removed by unscrewing it from the steel block/base part before sol-
dering.
Temperature sensor installation
The sensor normally has a cable with a temperature sensor which have to be mounted to the pipework using cable ties or to
the lid of the larger strainer models. The temperature sensor compensate for the change in the dielectrical constant with the
temperature and make the measurement more accurate when starting the system. Refrigeration systems working with NH3
can operate well without a temperature sensor.
The temperature sensor should
be mounted to a pipe in posi-
tion 3 or 9 o'clock with cable
ties as shown.
For strainer houses the clip can
be used for attaching it to the
lid

Unscrew the complete sensor part before solder-
ing.
Use two wrenches when dismantling and installing
the HBX-Sensor. One to turn the sensor and one on
to stabilize the steel block to avoid stress to the
soldering's.
Use thread sealant.
We recommend using liquid thread sealant when
installing the sensor
Insulate the entire
mechanical sensor
part with insulation
foam.
