INTRODUCTION
The high accuracy outside temperature transmitter incorporates a precision platinum RTD
in a weatherproof enclosure with a sun and wind shield to monitor outside temperature
levels. A transmitter that provides a high accuracy signal with excellent long term stability,
low hysteresis and fast response is available with various ranges. A compact Polycarbonate
enclosure with a hinged and gasketed cover is provided for ease of installation.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the temperature.
Failure to follow these instructions may result in product damage. Do not use in an
explosive or hazardous environment, with combustible or flammable gases, as a safety
or emergency stop device or in any other application where failure of the product could
result in personal injury.
Do not exceed the device ratings
.
MOUNTING
Select a suitable mounting spot on an exterior wall where the temperature sensor is best protected from direct exposure to sunlight, wind, etc.
preferably on a north facing wall. Do not mount the sensor near opening windows, supply/exhaust air louvres or other known air disturbances.
Avoid areas where the sensor is exposed to vibrations or rapid temperature changes.
The temperature sensor provides a connection hole for 1/2" conduit. Run a length of
conduit through exterior wall and seal. Use 14-22 AWG shielded wiring for all connections
and do not locate the device wires in the same conduit with wiring used to supply inductive
loads such as motors. Make all connections in accordance with national and local codes.
The temperature sensor installs directly on an exterior wall using the two integrated
mounting holes provided on the enclosure. Select the best mounting technique based
on the exterior wall material. The two mounting holes are suitable for a #10 size screw (not
supplied). The sensor fitting must be pointing down. See Figure 1.
The enclosure has a hinged cover with a latch. Open the cover by pulling slightly on the
latch on the right side of the enclosure. At the same time pulling on the cover, as illustrated
in Figure 2.
A 1/2" NPT connection hole is provided in the back of the enclosure. Connect the EMT
connector with a locknut. See Figure 3. It is recommended that weatherproof conduit be
used. An optional cable gland fitting is available. See Figure 4.
Make wiring connections as per the “wiring” illustrations on Page 2.
Swing door closed until securely latched. For added security, two screws are provided that
may be installed in the integrated screw tabs. See Figure 5.
