General Applications
Over 90 years of manufacturing,
research and design makes Watlow
a world class supplier of temperature
measurement products. We have
designed and manufactured millions
of thermocouples for industrial and
commercial equipment. People
involved in critical process control of
food, plastics and metal rely on our

Thermocouples
General Applications
Construction and Tolerances
Construction
Thermocouples feature flexible
SERV-RITE
®
wire insulated with
woven fiberglass or high temperature
engineered resins. For added
protection against abrasion,
products can be provided with
stainless steel wire braid and flexible
armor. ASTM E 230 color-coding
identifies standard catalog
thermocouple types (see reference
chart on inside back cover).
The addition of a metal sheath over
the thermocouple provides rigidity for
accurate placement and added
protection of the sensing junction.
Mounting options include springs,
ring terminals, specialized bolts, pipe
style clamps and shims.
How to Order
• Determine style of thermocouple
required
• Complete the eleven digit part
number as determined by the
following parameters:
• Construction
• Diameter
• Calibration
• Lead protection
• Junction
• Sheath length
• Lead length
• Terminations/options
Note: All eleven spaces must be
filled in.
