Abstract

A kind of tungsten-rhenium thermocouple with regulating and monitoring tap, apply to measurement testing region. The invention is composed by junction box, protecting tube, regulating-monitoring tap, thermocouple, patch board. junction box connect with protecting tube, built thermocouple in protecting tube and connect with patch board of junction box internal. Protecting tube inside has regulating- monitoring tap, the tap position is at protecting tube center line; Protecting tube inside has regulating- monitoring tap, the tap position at one side of protecting tube; stuff protecting tube are metal, ceramics cermets; thermocouple are noble metal S, R, B; thermocouple are cheap metal K, E, N, J, T, C, D; thermocouple is single branch; Thermocouple is two branches. The invention obligate regulating- monitoring temperature hub in thermocouple, extraordinary convenience; because thermocouple's environment and condition is same, just insert gagged thermocouple into preformed hole to reach thermal balance, then can process regulating or monitoring to original system, thereby solve accuracy problem of scene's thermometric bumber.

Description

Technical field: [0001] The invention belongs to the field of measurement and testing, in particular to a calibration and monitoring method for an on-site temperature measurement system. Background technique: [0002] At present, temperature measurement technology in the field of metrology and testing at home and abroad is becoming more and more important, because temperature is one of the important parameters of industrial process control, and the accuracy of temperature measurement directly affects product quality, energy consumption and equipment life. For this reason, all countries attach great importance to it, and are striving to find an online calibration or monitoring method for the on-site temperature measurement system. The commonly used method is to use another set of temperature measurement system to compare with its temperature display value near the temperature measurement point. The disadvantage of this method is that it is difficult to fully meet the environm...
