Explosion-proof Thermocouple (Thermal Resistance)with Temperature Transmitter Display Tube

  • Product Detials:

    The Application of Thermocouple:

    Thermocouple is usually used with display meter, recording meter and computer etc. to directly measure temperature of liquid ,vapor, gas medium and solid surface ranging from -200oC to 1300oC during various production processes with output of 4~20 Ma.

    Features:

    1.Multi explosion-proof type, good explosion-proof performance.

    2.Spring thermal element with good shock-resistant performance.

    3.Wide measuring range.

    4.High mechanical strength and good pressure-resistant performance.

    The Main Technical Parameters:

    1.Standard: IEC 584, IEC 1515, IEC 751, GB 3836-2000, JB/T 5518-91, JB/T 7391-94.

    2.Output Signal: 4~20Ma, Loading Resistance:250Ω, Transforming Wire Resistance:100Ω.

    3.Output Method: Two Wire.

    4.Accuracy Class of Temperature Transmitter:0.1, 0.2 ,0.5.

    5.Accuracy of Display Meter: Analog lndication Class:2.5.

    6.Digital Display Class:0.1.

    7.Power Supply:24v.DC±10%.

    8.Protection Class: IP65.

    9.Explosion-proof Class:

           Explosion-separation: dll BT4, dll CT5, dll CT6

           Intrinsic Safety: iall CT 6.

    10.Insultation Resistance

           Insulation resistance between instrument output wire connecting head and outer case shoule be no less than 50mΩ

    11.Thermal Response Time

           When the temperature has step-jumping change, the needed time for current output signal of instrument changes to 50% of the step-jumping change, this time is called thermal response time, indicating with t0.5. When step-jumping response stable time of temperature transmitter is no more than 1/5 times of t0.5, thermal response time of instrument shall be considered as the thermal response time of thermocouple(thermal resistance)

           When step-jumping response stable time of temperature transmitter is no more than 1/2 times of t0.5, thermal response time of ins.trument shall be considered as the thermal response time of temperature transmitter

    12.Basic Error:

          The basic error of instrument should be no less than the compound error caused by thermocouple(thermal resistance) and temperature transmitter.
