3.2.3.2 Installation
The Humidity Sensor is normally mounted in the bulkhead
using the compression fitting. However, other mounting
locations may be used to meet user requirements.
CAUTION:
The sensing element is sealed within the sensor
assembly protected against mechanical damage by a
slotted housing cover. Under no circumstances should
the sensing element be touched. The sensor should
never be cleaned using compressed air. Dust and dirt
particles can be removed by blowing gently. There are
no user serviceable parts in the Model 5112 sensor.
The Control Unit may be placed on any surface near the test
chamber or installed into a panel 3.62”x3.6” (92x92mm
cutout) using the optional mounting clips.
Installation of the Dehumidification System is as follows:
1. Locate the desiccator at a convenient location near the
left-hand side of the chamber. Place the pump at a
convenient location near the desiccator or on the floor as
shown in Figure 3.2-5.

2. Insert one end of the length of supplied plastic tube into
the lower hose barb on the chamber.
3. Cut the tube and insert the other end into the INLET or
vacuum side of the pump.
