Rigid bulb transmitter mounting is shown in Figure 5. The transmitter is secured to the
flange by a set screw. The dimensions of the rigid bulb transmitter are shown in
Figure 14.
When installing rigid bulb temperature transmitters on insulated ducts, the insulation
must not cover any portion of the bulb (Figure 11). 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 a remote
bulb transmitter must be used.

Remote Bulb
The remote bulb transmitter mounting is shown in Figure 6. Secure the transmitter to
the flange by tightening the set screw. The well mounting of the remote bulb
transmitter is shown in Figure 7. The set screw on the well secures the transmitter to
the mounting plate.
Dimensions for the remote bulb transmitter are shown in Figure 14.
