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.
CAUTION
Avoid excessive torque on all threaded connections
.
WARNING
Do not exceed the marked maximum operating pressure in normal operation.
WARNING
Do not use as a safety device.
The marked Proof Pressure is provided to give the maximum allowable pressure without
causing permanent damage to the temperature switch in the event of an over-pressure
condition. Set pressure relief/safety valves below this setting.
PROCESS MEDIA
Process media must be compatible with the wetted materials listed in Chapter 5.
Compatibility is defined by an “A” rating in the Chemical Resistance Guide for Metals
and Alloys, the Chemical Resistance Guide for Plastics, and the Chemical Resistance
Guide for Elastomers, all published by Compass Publications, and available from the
National Association of Corrosion Engineers (NACE), Houston, Texas; telephone 281
