Explosion-proof corrosion-resistant lining tetrafluoro temperature transmitter

Abstract

The invention belongs to the technical field of a measuring device and particularly relates to an explosion-proof corrosion-resistant lining tetrafluoro temperature transmitter. The device comprises ajunction box, a mounting base, a protection tube, a core tube and an explosion-proof tube, wherein the bottom of the junction box is fixedly connected with the mounting base through screws, the bottom of the mounting base is in threaded connection with the protection tube, the core tube is inserted into the protection tube, and the explosion-proof tube is inserted into the core tube. The explosion-proof corrosion-resistant lining tetrafluoro temperature transmitter is advantaged in that through combination and application of accessories, the polytetrafluoroethylene lining tube can be used asa main body material of the protection tube, strong acid and strong alkali are resisted to achieve the anti-corrosion purpose, an inner threaded tube is combined in the protective tube, the inner corrugated tube and the corrugated tube can be combined with each other by being matched with the corrugated tube outside the additionally-arranged core tube, shock waves can be absorbed and buffered conveniently when explosion is generated, the high-strength rubber tube and a metal wire woven mesh are matched inside the explosion-proof tube, the risk of external explosion can be effectively reduced,and use stability and safety of the temperature transmitter are guaranteed.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to an explosion-proof, corrosion-resistant and PTFE-lined temperature transmitter. Background technique [0002] Measuring device refers to the totality of measuring instruments and auxiliary equipment combined for measurement needs. Some auxiliary equipment or tools used for measurement are also often included in the list of commonly used measuring tools, and the temperature measuring device is a category of measuring devices. [0003] A temperature transmitter is an instrument used to measure temperature. The temperature transmitter uses thermocouples and thermal resistances as temperature measuring elements, and the output signal from the temperature measuring elements is sent to the transmitter module, after voltage stabilization filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse After protection and other circuit...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an explosion-proof and anti-corrosion PTFE temperature transmitter to solve the problem of strong acid and strong corrosion of the existing temperature transmitter proposed in the above background technology in the special environment of the industrial use process. In some cases, the stability of the temperature transmitter cannot be guaranteed, and in the event of an emergency, such as an explosion problem, there is a lack of effective explosion-proof methods, and there is no effective mitigation of the impact of the explosion. The tube is very easy to produce an open flame in an instant, which will cause greater environmental hazards for some flammable industrial environments, and the stability and safety of the temperature transmitter cannot be effectively guaranteed.
