INDUSTRIAL THERMOCOUPLES

STYLE T-5590 (U.S. Patent 3,625,775)

Multi-purpose high temperature thermocouple assembly developed for continous 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)

 This 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 elminate 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 cermets.
