Installation
- Temperature Transmitters may be mounted in any position on a vertical surface.
- Installation may be made inside or outside of ducts and near fans, compressors, ducts, and air conditioning equipment. Transmitters, generally, are not affected by light vibration.
Room transmitters
The TT 184 Room Temperature Transmitter can be mounted to existing rough-in
devices or to the wall, using various tubing terminal kits. See TB 145
(Product Number 155-210P25) for all the mounting options.
Typical installation procedures for a finished drywall, plywood, paneling, or
other type of sheathing material are as follows (Figure 1):
-
Place the template provided with the wall plate on the wall at the desired location.
-
Drill two 5/32-inch diameter holes for #6 wall plate mounting screws.
-
Use a 1-1/4-inch diameter hole saw to drill an access hole in the drywall where indicated on the template. Figure 1. Room Transmitter Mounting in a Finished Wall Using the Spring Clip Mounting Kit.
-
Insert the clips from the Spring Clip Mounting Kit 182-685 with the long leg going through the 1-1/4-inch access hole and resting flat against the back surface of the drywall. Align the screw holes in the clips with the holes on the wall.
-
Fish the air lines through the 1-1/4-inch access hole. Using tubing kit 180-896, or any tubing kit suitable for finished wall installation, connect 5/32-inch tubing to the bottom port on the back of the wall plate and secure the connection using tube retainers.
-
Install the wall plate on the wall using mounting screws furnished with the transmitter. The wall plate has slotted holes to allow leveling of the wall plate.
-
Carefully plug the transmitter into the wall plate.
NOTE: To facilitate plugging the transmitter into the O-rings in the wall plate, wet or moisten the supply and return ports. This wetting or moistening will lubricate and allow the unit to slip through the O-rings more easily. -
Secure the transmitter to the wall plate using the two captive screws.
-
Place the cover over the transmitter and fasten it with the two cover screws.
Rigid bulb
Figure 2 shows mounting the Rigid Bulb Transmitter. The transmitter is secured
to the flange by a set screw.
When installing rigid bulb temperature transmitters on insulated ducts, the
insulation must not cover any portion of the bulb (See Figure 3). Incorrect
installation of the rigid bulb can create a 16% of span error (for example,
8°F error using the 50 to 100°F transmitter).
NOTE: If it is not possible to properly install a rigid bulb transmitter,
then you must use a remote bulb transmitter. Remote averaging bulb
Figure 4 shows two methods for mounting the Remote Averaging Bulb.
Figure 4. Mounting the Averaging Bulb in Large Ducts.
- Uncoil the averaging bulb carefully. Avoid sharp bends or kinks in the sensing element.
- Attach the bulb to the strap hangers with wire ties as shown in Figure 4 or with plastic tie wraps.
Remote bulb
Figure 5 shows mounting the Remote Bulb transmitter. Secure the transmitter to
the flange by tightening the set screw.
Figure 6 shows the well mounting of the remote bulb transmitter. The set screw on the well secures the well to the mounting plate.

Calibration
This transmitter is factory calibrated. The transmitter should not be
calibrated in the field. The only way to determine if the temperature
transmitter is out of calibration (either span adjust or zero adjust) is with
an accurate two-temperature bath and an accurate pressure gauge. Span
adjustment or zero adjustment cannot be made in the field because of the
equipment and time required.
Because of variations in lengths of pneumatic tubing, airflow through
restrictors, ambient temperatures, and so on, there will be small errors
between actual temperature at sensing element and gauge indication. For minor
improvements in accuracy, adjust the pointer on the receiver gauge to agree
with the temperature at the sensing element.
Additional suggestions are given in the Table 3 Troubleshooting Chart.
Preventive Maintenance
The temperature transmitter does not require lubrication.
Periodically clean dust from the transmitter body using a soft hairbrush.
Check yearly to ensure that temperature at sensing element agrees with
temperature at gauge.
