E. INSTALLING THE HUMIDITY SENSOR
Figure 6: Humidity Sensor Mounting
The Relative Humidity sensor should be mounted in a sheltered area, preferably on
the north side of a building under the eaves to prevent sun-heated air from rising up
the side of the building and affecting the relative humidity at the sensor. If a shel-
tered area is not available the sensor can be mounted in a self-aspirating radiation
shield.
Wiring should be through 1/2" conduit or alternatively through the rubber grommet
provided in the 1/2" EMT elbow conduit.
The relative humidity sensor is supplied with a standard 25-foot cable. The cable
provided is a 22 gauge, 2 conductor shielded cable with a ground drain lead. If
additional cable is required, a good splice and waterproof insulation are essential;
merely twisting the respective wires together is not adequate.
Once the sensor has been placed, route the cable back to the console. It may be
convenient to combine this step with routing of the wind sensor cable.
Using a Phillips screw driver, attach the humidity cable to the back of the console.
The black and red wire should be attached to the appropriately labeled section on
the back panel. Attach the "bare" wire to the chassis ground terminal.
