Industrial thermocouple assembly as a temperature sensor, usually display instruments, recording instruments and supporting the use of electronic regulator. Fabricated thermocouple can be measured directly from a variety of production in the range of 0 ℃ to 1800 ℃ of liquid vapor and gases as well as the surface temperature of solids.
According to state regulations, I produced in accordance with IEC international standard indexing number of platinum and rhodium 30 - 6 platinum and rhodium, platinum and rhodium 10 - platinum, nickel chromium - nickel silicon, nickel chromium - constantan thermocouple assembly and so on.
Assembly thermocouple temperature sensing element is usually installed fixtures and junction boxes composition and other major components.
Thermocouple Pressure: generally refers to rupture at the working temperature protection tube can withstand a static external pressure.
Thermocouple minimum insertion depth: not less than 8-10 times the outer diameter of the protective sleeve (special products out exceptions)
Insulation resistance: When the ambient air temperature is 15-35 ℃, relative humidity (80% Insulation resistance ≥5 megohms (voltage 100V) with a splash thermocouple junction box, relative humidity of 93 ± 3 ℃ when, ≥0.5 megohms insulation resistance (voltage 100V)
Insulation resistance at high temperatures: Thermocouples at high temperatures, the thermal electrode (including the double-supported) Insulation resistance (per meters) and protective tube and dual branch heat between the electrodes should be greater than the value specified in the following table.
