用耐高温的KX或EX型补偿导线作测温材料，与其它结构件一起，即可组成各种不同用途的补偿导线型热电偶。 The special assembly type thermocouple uses high temperature resistant KX or EX type compensating wire as the temperature measuring material. Together with other structural parts, it can form compensating wire type thermocouples for various purposes.
★ The compression spring type thermocouple presses the measurement end of the thermocouple against the surface of the object to be measured by the action of the compression spring to improve the heat transfer effect and the accuracy of temperature measurement. It is suitable for the measurement of plastic extruder, textile and food industries. temperature.
★ Hot-end bare thermocouple It is a compensating wire made of thermocouple material. One end is welded into a bare thermal junction as the measurement end. The other end is welded with two pieces of lugs or flat sockets. It is characterized by extremely fast thermal response and very low price, which is suitable for temperature measurement of analytical instruments and various small equipment.
★ The hoop type thermocouple is a compensating wire made of thermocouple material. One end is welded to a hoop that can shrink in diameter. The hoop is installed outside the pipe under test. The thermocouple can be used to collect heat through the hoop. Measure the temperature of the pipe surface. The product is easy to install, simple in structure, fast in thermal response, reliable in measurement and low in price.
This product is used to measure the temperature of gas, especially suitable for the exhaust port temperature measurement of high-speed diesel engines. Because its thermal junction is exposed in a protective tube with two window holes, it has the characteristics of fast thermal response and no fear of collision.
作为测量温度的变送器通常和显示仪表、记录仪表和电子调节器配套使用.它可以直接测量各种生产过程中从0℃到1800℃范围的液体、蒸汽和气体介质以及固体的表面温度。 Special assembled thermocouples as temperature transmitters are usually used in conjunction with display instruments, recording instruments and electronic regulators. It can directly measure liquid, steam and gaseous media in the range from 0 ° C to 1800 ° C in various production processes and Surface temperature of the solid. Nominal pressure of thermocouple: Generally refers to the static external pressure that the protection tube can withstand at operating temperature and rupture.
The minimum insertion depth of the thermocouple: should be not less than 8-10 times the outer diameter of its protective sleeve (except special products)
When the ambient air temperature is 15-35 ° C and the relative humidity is less than 80%, the insulation resistance is ≥ 5 megohms (voltage 100V). Thermocouple with splash-proof junction box, when the relative temperature is 93 ± 3 ℃, the insulation resistance is ≥0.5 megohm (voltage 100V)
As a temperature sensor, industrial assembled thermocouple is usually used together with display instrument, recording instrument and electronic regulator. Fabricated thermocouples can directly measure the surface temperature of liquid vapor and gaseous media and solids in the range of 0 ° C to 1800 ° C in various productions.
According to national regulations, our company produces assembled thermocouples that conform to the IEC international standard graduation numbers of platinum-rhodium 30-platinum rhodium 6, platinum-rhodium 10-platinum, nickel-chromium-nickel silicon, nickel-chromium- Constantan, and so on.
通常由感温元件、安装固定装置和接线盒等主要部件组成。 Specially assembled thermocouples usually consist of the main components such as temperature sensing elements, mounting fixtures and junction boxes.
