Mounting the T/H Sensor in a Davis Radiation Shield
In order to attach the External Temperature/Humidity Sensor (T/H Sensor) to
the Radiation Shield, you will need to expose the Radiation Shield's closed
plate. Refer to your Radiation Shield installation manual for complete instruc-
tions on mounting the Radiation Shield.
1. Position the T/H Sensor
over the four mounting
posts on the closed plate,
lining up the holes in the
mounting posts with the
holes in the T/H Sensor's
casing as shown.
Note: Make sure you orient the T/H Sensor with the long side of the sensor parallel to the long side of
the plate.
2. Using three #4 x 1/2" pan head self-threading screws, attach THREE
CORNERS of the T/H Sensor to the closed plate.
Do not attach the final corner yet.
Place the cable clamp around the sensor cable approximately 4" (10 cm)
3.
from the T/H Sensor.
Attach the cable clamp to the remain-
4.
ing corner of the T/H Sensor and to
the closed plate (using a #4 x 1/2"
pan head self-threading screw and a
#4 flat washer) so that a loop of cable
is formed.
Make sure to mount the clamp with
the flat side up and the bulge side
down. Tighten the screw completely
so that the cable cannot move within
the cable clamp.
Mounting the T/H Sensor without a Radiation Shield
If necessary, disconnect the sensor cable from the junction box/SIM.
1.
2. Hold the sensor housing against the mounting surface and use a pencil to
mark the location of the four holes on the sensor housing.
3. Use a 1/16" or 3/32"drill bit (2 mm) drill bit to make pilot holes in these
locations.
4. Drive the four #4 x 1/2" pan head self-threading screws through the holes
on the sensor housing and into the mounting surface.
