Thermocouple Calibration Furnace Test Specification
1 Scope
This instruction applies to (300 to 1,500) within the range includes ℃ with and without thermostat thermostat horizontal tubular thermoelectric
Even test furnace (hereinafter referred to as test furnace) test temperature field. For the vertical test tube furnace, annealing temperature field measurement
Trial, execution can refer to this specification.
2 Terminology
2.1 axial temperature field axialtemperaturefield
Means test furnace along the central axis of the tube furnace temperature distribution.
2.2 radial temperature field radialtemperaturefield
It means test furnace along the furnace temperature distribution in the cross section.
2.3 fixed standard even fixedstandardsforthermocouple
It refers to a predetermined position in the axial or radial fixed and verification furnace is used to measure changes in standard thermocouple.
2.4 mobile standard even movingstandardsforthermocouple
It refers to a predetermined axial or radial position for standard thermocouple verification furnace temperature field distribution.
