PROCESS CONNECTIONS
The process connections are:
Model 100T: ½” - 14 NPT male standard. The .25 in. (6.4 mm)
dia. probe extends 3.0 in. (76 mm) past the end of the pipe thread.
Model 100TC: ½” - 14 NPT male standard. The .38 in. (9.7 mm)
dia. probe extends 4.50 in. (114 mm) min. from the end of the
pipe thread, and can be extended an additional 9.5 in. (241 mm).
After this length adjustment, torque the gland nut in the pipe fitting
to 230 ± 20 in-lb (26.0 ± 2.3 newton-meters).
When installing the Temperature Switch, always:
Make sure that the unit and your system have matching threads.
Use the wrench flats provided.
Seal all joints with pipe joint sealing compound.
Avoid excessive torque on all threaded connections.
PROCESS MEDIA
Process media must be compatible with the wetted materials listed
in Chapter 4 starting on page 10. Compatibility is defined by an
“A” rating in the Chemical Resistance Guide for Metals and
Alloys, and, as applicable, the Chemical Resistance Guide for
Plastics or the Chemical Resistance Guide for Elastomers. All are
published by Compass Publications and are available from the
National Association of Corrosion Engineers (NACE), Houston,
Texas; telephone 281 228-6200.
ELECTRICAL CONNECTIONS
18 AWG free leads, 18 inches (48.3 cm) long are standard. See
Figure 2 below for color codes.
All field wiring must comply with requirements of the NEC or
applicable local or national electrical codes, including wire
gauges and insulation temperature ratings. Conduit seals may
