Installation and Maintenance
2.1
General
In order to install the THS-3, the following equipment will be needed:
a)
a
5/16
” hex wrench for attaching the THS to the support arm mount;
b)
a ¼ “ wrench to tighten the U-Bolt assembly; and
c)
cable ties to attach the cable to the tower assembly.
Prior to installation observe the site and ensure the following can be achieved for optimum
performance of the sensor:
a)
The sensor should be in the open, in a shade free area to ensure
accurate temperature readings.
b)
The sensor should be well away from external sources of heat (i.e. any
equipment at the site that might generate heat).
c)
The sensor support arm should be levelled (tower mount should be
levelled).
2.1.1
Installation Height
Correct installation height is dependent on regulations for the jurisdiction in which the equipment is
to be deployed. Ensure you review local regulations prior to installation.
In the United States the THS-3 Temperature & Humidity sensor is to be installed on the south side of
the mast 4 to 8 feet above ground. The Canadian regulations are to install the sensor on the south
side of the mast 1 to 1.3 meters above the ground.
Sensor height is also dependant on regional weather conditions. The sensor should be installed at a
height that is above the worst case estimate for snow levels in the area.
2.2
Tower Mounting
The procedure for tower mounting the THS-3 is as follows:
1.
Remove the locking screw from the support arm mount and then slide the THS-3
assembly support arm mount (Figure 2-1). If the sensor is deployed in a coastal or
otherwise corrosive environment, lubricate the locking screw with white lithium grease
to prevent seizing. Secure the assembly with the locking screw.
