之间的区别有： The differences between armored thermocouples and fabricated thermocouples are:
To put it simply: the armored wire is made by a specialized manufacturer.Its protective tube, insulation layer, and even wire are stretched as a whole.It has high strength, can be bent, and is not affected by the length.The assembly thermocouple is made of 16 or other diameter stainless steel tubes are made of protective sleeves, which are covered with thermocouple temperature sensing elements that have been insulated with ceramic beads, and the junction box can be installed. Both have their own strengths, and users can choose according to their needs. .
It mainly produces primary instruments such as thermocouples and thermal resistors, and the assembled thermocouples produced adopt international IEC standards. At the same time, the series and pattern spectrum of the thermocouples uniformly designed by the Ministry of Machinery and Electronics Industry are adopted. Overview of assembled thermocouples Industrial assembled thermocouples as temperature transmitters are usually used in conjunction with display instruments, recording instruments and electronic regulators. It can directly measure liquids ranging from 0 ° C to 1800 ° C in various production processes. , Vapor and gaseous media, and the surface temperature of solids. 。 Assembled thermocouples with index number of platinum rhodium 30-platinum rhodium 6, platinum rhodium 10-platinum, nickel chromium-nickel silicon, nickel chromium-constantan, etc. Assembly thermocouples usually consist of main components such as temperature sensing elements, mounting fixtures, and junction boxes.
The assembled thermocouple produced by the company can directly measure the temperature of liquid, steam and gas medium and solid surface in the range of 0 ℃ ～ 1800 ℃ where hydrocarbons and other explosives are present on the production site. It is usually used together with display instruments, recording instruments, and computers.
◆ Simple assembly and easy replacement
◆ Pressure spring type temperature sensing element, good shock resistance
◆ Large measuring range
◆ High mechanical strength and good pressure resistance
的电极由两根不同的导体材质组成，当测量端与参比端存在温差时，就会产生热电势，工作仪表便会显示热电势所对应的温度值。 The electrode of the assembled thermocouple is composed of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential will be generated, and the working instrument will display the temperature value corresponding to the thermoelectric potential.
※The main technical parameters
1. Product implementation standards
IEC584 IEC1515 GB / T6839-1997 JB / T5582-91
2. Room temperature insulation resistance The thermal resistance is 25 ± 15 ℃ at ambient temperature, the relative humidity is not greater than 80%, and the test voltage is 500 ± 50V (DC). The insulation resistance between the electrode and the outer sleeve is ≥1000MΩ.
