Abstract

The invention belongs to a quick-heat-conduction multi-point armoured thermocouple (thermal resistor), which consists of a junction box, a protective casing and temperature measurement elements. The protective casing consists of an upper protective casing and a lower protective casing; the upper end of the upper protective casing is fixedly arranged on the junction box coaxially; the temperature measurement elements are fixedly arranged on the junction box coaxially and are arranged in the protective casing; the temperature measurement element in the lower protective casing is positioned and arranged on a conductive sliding block; and the conductive sliding block slides radially and is arranged on an inner wall of the lower protective casing. The thermocouple (thermal resistor) has quick response to the temperature measurement, relatively high accuracy and safety of the temperature measurement, relatively low maintenance and repair cost and convenient construction, and is quick-heat-conduction multi-point armoured thermocouple (thermal resistor) with relatively strong innovation.

Description

technical field [0001] The invention belongs to thermocouples (resistances) in the field of temperature sensors, in particular to a rapid heat conduction multi-point armored thermocouples (resistances). Background technique [0002] Thermocouple (resistance) is one of the commonly used temperature sensors, and multi-point thermocouple (resistance) is one of the most widely used temperature measuring components in process detection, especially in reactors, converters and other devices in the chemical industry . The temperature of the measured medium changes frequently during process detection, and temperature monitoring is especially important for process control. At present, the structure of thermocouple (resistor) in the industrial field is mainly composed of three parts: junction box, protective sleeve and measuring element. The measuring element is directly distributed in the protective sleeve. There are the following problems: 1. The temperature measuring element is pl...
