Fabricated Industrial Thermocouple

  Specifications As temperature sensors, fabricated thermocouples are used with display instruments, recorders, electronic regulators. They measure temperatures ranging form 0 ℃ ~1 800 of liquid, vapor, gas medium, and solid surfaces. Fabricated thermocouple is mainly composed of temperature-sensing element, fixed install devices, and junction box. Type B, S, K, E Main technical parameters

Type	Code	Graduation	Measurement Range	Limit of Error
Ni Cr - Cu Ni	WRK	E	0-800℃	±0.75%t
Ni Cr - Ni Si	WRN	K	0-1300℃	±0.75%t
Pt-13Rh/Pt	WRB	R	0-1600℃	±0.25%t
Pt-10Rh/Pt	WRP	S	0-1600℃	±0.25%t
Pt-30Rh/Pt-6Rh	WRR	B	0-1800℃	±0.25%t

Note: tis the actual temperature value of temperature-sensing element Time Constant

thermal inertia grade	time constant (sec.)
1	90-180

4	<10

   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
