INTRODUCTION
The high accuracy single point flying lead temperature transmitter utilizes a precision
sensor that is encapsulated in a 50 mm (2”) long x 6 mm (0.236”) diameter OD, 304
series stainless steel probe and is provided with 3.05 m (10’) of plenum rated FT-6 cable.
All probes provide excellent heat transfer, fast response and resistance to moisture
penetration. 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
sensor. 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
The flying lead transmitter can be used in several different types of applications where single point temperature monitoring is required.
Listed below are some typical applications
The flying lead sensor can be installed directly into any air duct. Select a suitable installation area in the middle of the duct. To achieve the best reading, do
not place in an area where air stratification may be present. Avoid areas where the sensor is exposed to vibrations or rapid temperature changes.
Once a suitable spot is selected, drill a 3/8” hole in the top of the duct and slide the probe through, mount
a length of flexible duct hanger from top to bottom of the duct. Mount the probe to the duct hanger
using a tube clamp or wire tie. See Figure 1.
The flying lead could also be used to measure pipe temperature. Select a suitable spot along the pipe,
remove a small section of insulation if present and set aside. It is recommended that thermal compound
be used to improve heat transfer. Spread a liberal amount on the pipe. Lay probe in thermal compound
and secure sensor to pipe using a worm gear clamp (not included).
For added protection it is recommended to wrap the probe cable around the pipe 1 to 2 times. Re-install
insulation if present, allowing sensor cable to protrude. See Figure 2.
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 shown in Figure 3.
A 1/2" NPT threaded connection hole is provided in the bottom of the enclosure. Screw the EMT connector
or cable gland connector in until tight. See Figure 4. It is recommended that weatherproof conduit or
cable gland fittings be used. The F style enclosure includes a 1/2" NPT to M16 thread adapter and cable
gland fitting.
Make wiring connections as per the “Wiring” illustrations on Page 2.
Swing door closed until securely latched. For added security, 2 screws are provided that may be installed
in the integrated screw tabs. See Figure 5.
