Multipoint thermocouple mounting component and multipoint thermocouple measuring device

Abstract

The invention provides a multipoint thermocouple mounting component, comprising a sleeve rod (21) as well as a mounting base (19), a sealing clamping sleeve (16) and a seal ring between the mounting base (19) and the sealing clamping sleeve (16), wherein the sleeve rod (21) is used for receiving multiple wires (7) and fixing a thermocouple probe (8), the mounting base (19) sheathes the sleeve rod(21), the mounting base (19) is configured for being used for being fixed on a to-be-measured container (1), and the sealing clamping sleeve (16) can be connected with the mounting base (19) by virtueof a screw thread, so that the seal ring is clamped on the peripheral surface of the sleeve rod (21) when the sealing clamping sleeve (16) is connected with the mounting base (19) by virtue of the screw thread. The invention also provides a multipoint thermocouple measuring device (2). The multipoint thermocouple mounting component provided by the invention has improved sealing property and can orient or adjust orientation of the probe.

Description

technical field [0001] The present invention relates to the technical field of measurement devices, in particular to a multi-point thermocouple installation assembly and a multi-point thermocouple measurement device. Background technique [0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It can directly measure temperature, and convert the temperature signal into thermal electromotive force signal, and convert it into the temperature of the measured medium through electrical instruments. Thermocouples have many advantages such as simple structure, convenient manufacture, wide measurement range, high precision, small inertia, and easy remote transmission of output signals, and are widely used to measure the temperature of gas or liquid in containers or pipelines. Multipoint thermocouples are commonly used when measurement applications require simultaneous measurement of temperature parameters at multiple locations or w...

Problems solved by technology

However, the multi-wire structure of the above-mentioned multi-point thermocouple measurement device poses a challenge to the sealed installation of the multi-point thermocouple

[0004] In addition, the traditional multi-point thermocouple measurement device cannot guarantee the orientation of the probe, or even know the orientation of the probe in the container. In extreme cases, the probe may deviate from the position to be measured, which will cause serious measurement lag problems , and seriously affect the measurement results
