Rigid bulb
Figure 2 shows mounting the Rigid Bulb Transmitter.
The transmitter is secured to the flange by a set
screw.
Figure 2. Rigid Bulb Mounting.
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 (e.g., 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.
Figure 3. Installation on Insulated Ducts.
Remote averaging bulb
Figure 4 shows two methods for mounting the
Remote Averaging Bulb.
Figure 4. Mounting the Averaging Bulb in Large
Ducts.
1. Uncoil the averaging bulb carefully. Avoid sharp
bends or kinks in the sensing element.
2. 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 5. Remote Bulb Mounting.
Figure 6 shows the well mounting of the remote bulb
transmitter. The set screw on the well secures the
well to the mounting plate.
