ADVANTAGES
The thermometers
listed in this site have been designed to
provide accurate and dependable temperature
measurements for industrial and laboratory
applications. Their rugged all-metal construction,
exceptional readability and proven reliability
all combine to assure maximum service. Weston
thermometers are available in a variety
of ranges, sizes and types for the usual
industrial and laboratory applications.
Rugged:
All-metal construction with corrosion resistant
stainless steel stems and connection nuts
assure long, dependable service. No pivots,
complicated mechanisms or parts are used.
The absence of gears or connection links,
factors which tend to introduce errors and
frequently result in complete failure, eliminates
wear and friction.
Pressure Tested:
The 304 stainless steel stem and connection
nut on industrial models have been tested
at 1000 psi. It is recommended, however,
that on installations involving high pressure,
wells be used in accordance with standard
thermometer practice, thereby providing
additional insurance to the installation.
Easy to install:
Thermometer connection
nuts have National Pipe Threads. Easily
mounted at any angle for convenience in
reading.
Easy to Read:
The circular dial
and pointer method of measuring temperature
permits the use of easily read, widely
spaced scale markings.
Typical Applications:
- Steam Power
Stations
- Chemical Processes
- Solar Energy
- Heating, Ventilating,
Air Conditioning, Etc.
- Breweries
- Food Processing
- Chemical Storage
- Diesel Generator
Sets
- Plant Maintenance
- O.E.M. Industrial

Sensitive
Element:
The heart of Weston
Thermometers is the helix-sensing element.
The Weston helix is more than just the "run
of the mill" sensing element, for Weston's
exclusive fabrication assures long-term
accuracy (up to ± 1/2 % of the entire
scale). From the very beginning of the formation
of the bimetal helix, to its careful sizing
and aging to eliminate inherent stresses,
to its shock mounted inclusion in the stainless
steel stem, every Weston thermometer has
the built-in stamina to give years of dependable
and accurate service. The pointer is driven
directly by the sensing element-no pivots
or complicated linkage mechanisms are used.
Liquid column separation and leakage are
problems of the past when you specify Weston
all metal thermometers.
Unaffected by
over or under Temperatures:
Abnormal operating
conditions, which may temporarily swing
the pointer beyond the end of the scale,
will not impair the thermometer accuracy.
50% overswing on ranges up to 500°F
and 10% for ranges of 500°F to 750°
F as well as 50% underswing on all ranges
are well within the safe operating limits
of the bimetal element.
Reliable:
The bimetal principle
of temperature measurement eliminates
the need for gases, liquids or capillary
connections. Since Weston thermometers
are of all-metal construction, breakage
and maintenance are materially reduced.
Calibration:
All thermometers
are calibrated with standards directly
traceable to the National Bureau of Standards.
Special Applications:
The thermometers
shown here have standard ranges and stem
lengths. If your application involves
other than standard thermometers, odd
size connection nuts, ranges, specially
marked or calibrated scale plates, odd
stem lengths, special fabricating materials,
finishing and special waterproofing-please
