Thermal sleeve type thermocouple

Productoverview:
WRN series Thermal sleeve type thermocouple The heat protection casing and thermocouple separation combination, the use of the user can be nested in thermal protection tube welding equipment or pipeline, and then loaded thermocouple can be used, has the advantages of improving the protection of pipe work pressure and service life, and convenient maintenance and replacement in the thermocouple, the factory production of heat set the protective tube and deep blind hole processing technology, the protection of the end of the pipe without welding, thereby improving heat protection tube strength and service life.
Two, work principle:
WRN series Thermal sleeve type thermocouple Two different components of the conductor (called thermocouple wire or thermal electrode) is connected to the two ends of the synthetic circuit, when the junction temperature at the same time, in the loop will produce electromotive force, this phenomenon is called the thermoelectric effect, and this is called thermal electromotive force emf. A thermocouple is used to measure temperature of this principle, which is directly used for measuring the temperature of a medium called the working end (also known as the measuring end), the other end is called the cold end (also known as the end of the cold end compensation); and display instrument or meter display instrument connection, will point out that the thermoelectric potential generated by thermocouple.
Three, application:
WRN series Thermal sleeve type thermocouple Suitable for steam pipe, boiler and other on temperature, pressure and flow requirements of the place.

Fourth, the main features:
1, simple assembly, convenient replacement;
2, a spring type temperature sensing element, good anti vibration performance;
3, a large range of temperature;
4, high mechanical strength, good pressure resistance.

Five, technical parameters:
1, electrical outlet: M20x1.5, NPT1/2;
2, size: M20x1.5, NPT1/2 connection;
3, protection grade: IP65.
Six, thermal sleeve type protective sleeve installation steps are as follows:
1, in the pipeline of the measured medium hole. In order to protect the triangle cone casing firmly installed on the pipe wall, the through holes can drill a diameter of 38mm, and then expanded to 42mm in diameter, 38mm diameter hole reaming will keep 10mm long.
2, the installation of welding casing. Install the casing length, should ensure the protection of the triangle cone sleeve firmly against the hole diameter of 38mm.
3, inserted into the protective sleeve. When the triangular cone protective sleeve with 38mm hole seal, protect casing and casing should be installed between the welding gap enough.
4, the protective sleeve is welded on the installation sleeve.
