4.2.2 Installing the Standard Sensors
Install all the sensors, carefully following the instructions and wiring diagrams
given below. If you need further advice on the installation and operation of
specific sensors, please read the installation manual provided for that sensor.
Handle all sensors and wiring with care. Rough handling can damage both the
mechanical and electrical integrity of the sensors.
CS215 Temperature/Relative Humidity Probe
The CS215 is fully integrated into the T351-RS Radiation Shield on the underside
of the enclosure and wired into the datalogger before despatch.
The sensor can be removed for periodic inspection/maintenance from inside the
enclosure. Loosen the large gland nut retaining the CS215 and gently pull upwards
on the threaded part of the sensor until it is completely removed. Do NOT pull the
sensor up by the cable, as you may damage it. Replace the sensor by re-inserting it
into the radiation shield through the gland until the threaded portion of the sensor
is about 3mm above the main gland body. Re-tighten the gland nut.

Figure 4 Wind Sentry Mounting
The 0300

-5 Wind Sentry is provided with a mounting bracket which fits directly
to a 26.9mm outside diameter (3/4'' nominal bore) pipe. The mounting device
consists of a two-piece male/female spigot, and is fitted with two band clamps. The
lower ‘orientation’ clamp secures the equipment to the mast. By loosening the
upper clamp, the complete bracket and sensors can be removed for maintenance,
and, by means of the spigot, replaced in exactly the same orientation, saving the
time and effort required in re-aligning the wind sensor to true north (see below).
Mount and align the Wind Sentry as follows (refer to Figure 4, above):
1. Ensure that the upper band clamp is fully tightened.
2. Open the lower ‘orientation’ clamp sufficiently so that the complete assembly
will easily slide onto the top of the mast.
3. Mount the complete Wind Sentry onto the top of the mast; only lightly tighten
the lower band clamp so that the assembly can be easily rotated.
