High Temperature Platinum-Rhodium Thermocouple B/S/R

Product description:JFAWZHigh temperature platinum-rhodium thermocouple B/S/Ris used as a sensor to measure temperature,usually matched with display instruments. It can directly measure temperature from -200C to 500C of liquid, vapor, gas medium and solid surface during variousproduction processes.
It is widely used in petroleum, chemical industry, machinery, metallurgy, electric
power, textile, food, atomic energy, aerospace and other industrial sectors and field
of science & technology.
Pt100, Pt1000 and Cu50 are optional.Features:It is designed unitedly in China, interface size is universal, good interchangeability.
The decomposition of the parts is good, easy to maintenance.
Low cost to change the consumable parts, complete in specifications
and high reliability.
Insulation resistance: the normal temperature insulation resistance of platinum
resistor should be more than 100MΩ.
the normal temperature insulation resistance of copper resistance
should not be less than 50MΩ.
The test voltage of normal temperature insulation resistance is 10~100VDC.
Self-heat effects: platinum resistance the max. current is 5mA,
the resulting of temperature raise is not than 0.3ºC.Product detail & technical parameter:Thermal inertia rate Time constant(s) Thermal inertia rate Time constant(s)One 90-180 410-30 Two 30-90 610 Min. insertion depth: Not less than 8 to 10 times of the outside diameter
of protective casing.
Insulationresistance: The insulation resistance of splash-proof junction box is 2 MΩ
when the ambient air temperature is 15-35ºC,
relative humidity <80%
and insulation resistance is 20MΩ(voltage 100V).Pt10, Pt100, R00 /R0=1.3850±0.001
