Description：
Productoverview: WRN series?Petrochemical special thermocouple?Professional for the petrochemical sector design, can directly measure the temperature range of 200 DEG C 1600 liquid, steam and gas and solid surface temperature. Two, work principle: WRN series?Petrochemical special 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?Petrochemical special thermocouple?Professional for the petrochemical sector design, can directly measure the temperature range of -200 DEG C 1600 liquid, steam and gas and solid surface temperature.
Four,?Nominal pressure: WRN series?Petrochemical special thermocouple?Generally refers to the normal temperature, protection tube can withstand the static pressure without rupture.?Not only the allowable working pressure and protection of pipe material, diameter, wall thickness, and its structure and installation method and the measured medium flow and related species. Five,?Main features: 1, simple assembly, convenient replacement; 2, the pressure spring type temperature sensing element, good anti vibration performance; 3, large range of temperature measurement; 4, high mechanical strength, good pressure resistance. Six,?Technical parameters: 1, electrical outlet: M20 * 1.5, NPT1/2; 2, size: M20 * 1.5, NPT1/2; 3, protection grade: IP65 head; Burst level 4: D II, BT4, D II CT5; 5, nominal pressure: 15 ~ 40MPa.
