Made in China High Quality Fabricated Thermocouple

  Product Description   Specifications
As temperature sensors, fabricated thermocouples are used with display instruments, recorders, electronic regulators. They measure temperatures ranging form 0 ℃ ~ 800 of liquid, vapor, gas medium, and solid surfaces.
Fabricated thermocouple is mainly composed of temperature-sensing element, fixed install devices, and junction box.

   Nominal pressure: generally refers to rupture at operating temperature protection tube can withstand a static external pressure.
   Minimum insertion depth: not less than 8-10 times the external diameter of its protective casing (except special products)     Insulation resistance: When the ambient air temperature is 15-35 ℃, relative humidity <80%, insulation resistance≥5 MQ (voltage 100V). Thermocouple junction box with a splash, when the relative temperature is 93 ± 3 ℃, insulation resistance ≥0.5 MQ (voltage 100V)
    insulation resistance in high temperature: insulation resistance among the thermal electrode (including double-supported), protective tube and double thermode should be greater than the value specified in the following table.

operating temperature	Test Temperature(℃)	insulation resistance(Ω)
≥600	600	72000
≥ 800	800	25000
≥1000	1000	5000
