Figure 9 Example Installation of HMP8 Model
1
Mount the probe head horizontally to prevent any water condensing on the probe head
from running to the sensors.
2
Let the cable hang loosely to prevent condensed water from running along the cable to
the probe head.
3
Attach the probe body to a wall or other surface using the two mounting clips (Vaisala
item 243257SP) supplied with the probe. Each clip attaches to the installation surface with
one screw (screw hole Ø 4.2 mm).
4
Cable to Modbus master or Indigo™ transmitter.
If the temperature of the measured environment differs greatly from ambient
temperature, the whole probe and preferably plenty of cable must be inside the
process. This prevents measurement inaccuracy caused by heat conduction along
the cable.
