Multi-purpose high temperature thermocouple assembly developed for continuous use
to 1600 °C (3000 °F) in both oxidizing or reducing atmospheres-pressures to 70 Kg/cm²
(1000 psi).
High Temperature Section:
Diameter = 12.7 mm (0.5 in)
Lengths = 76.3 to 433 mm (3 to 17 in)
Support Section "A":
Diameter = 15.9 mm (0.625 in)
Lengths = 102 to 1525 mm (4 to 60 in)
Total Length "L":
178 to 1960mm (7 to 77 in)
Industrial thermocouples may be used for temperatures above the Chromel / Alumel
range in environments that either destroy or render Platinum -Rhodium thermocouples
ineffective due to drift or ageing affects. The refractory Tungsten 5% Rhenium /
Tungsten 26% Rhenium element is protected against contamination or oxidation thru
the unique double insulation-double wall construction that selectively eliminates
all but the beneficial diffusion of Hydrogen. Internal thermocouple junction reliability
is maintained thru a new (patent pending) wire wrap / welding procedure to eliminate
the problems associated with thermal cycling welded junctions on refractory wires.
This sensor combines the stability and sensitivity (4.4 microvolts per °C) of the
new refractory thermocouple combinations with the atmospheric resistance and strength
of cermet’s.
APPLICATION
Gas generator temperature indication and control
Metal annealing, hardening and deoxidizing furnaces
Calcining and glazing Kiln temperature survey and control
Ceramic firing systems
Diffusion furnaces
Commercial 816 to 1600 °C (1500 to 3000 °F) ovens
Liquid steady state metal temperature surveys in Aluminum, Tin, Copper, Copper-Silver
alloys, Lithium
Long term temperature indication for baths with acid salts and corrosive acids (Cyanide
salts and molten borax excluded)

INSTALLATION
Compression fitting (½" NPT) with metal ferrule supplied with each sensor for immersion
control and pressure tight mounting to any pre-drilled and tapped chamber wall.
Insert threaded end and wrench tighten using hex head adjacent to threads. Insert
thermocouple thru hex head cap to desired immersion depth. Tighten cap ¼ turn beyond
finger tightness.
Note: Thermocouple head is supplied with necessary compression fitting for attachment
to probe. Attach wires, tighten compression fittings on thermocouple head prior
to process installation.
