Installing the 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
Refrigeration systems working with NH3 can operate well without a temperature sensor, but most other refrigerant benefit
from temperature measurement. The temperature measurement is used for offsetting the Zero point and makes the meas-
urement more accurate.
The sensor normally has a cable with a temperature sensor which has to be mounted to the pipework using cable ties or to
the lid of the larger strainer models. The mounting on the outside of the pipe provides sufficient accuracy. The temperature
sensor compensates for the change in the dielectrical constant with the temperature and make the measurement more ac-
curate when starting the system.
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
HBX-all types installation and calibration manual 03
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.
