WRKK-291 WRN-011 The specification of the above three types of thermocouple is fromΦ3 toΦ8mm. There fixed bolt and con

Example:A1.Product model and specification: WRKK-291 Φ3¡Á75¡Á35002.ThermocoupleType: Grade KTemperature measuring contact point: non-earthingFilling material: MgO (magnesia)Tolerance: Level 2 [+-2.5¡ãC (-40¡ãC-330¡ãC)]#Tolerance means the temperature converted by standard thermo electromotor forcegauge, then deduct the temperature of the measuring point, the maximum toleranceof the value. Outer diameter of element wire of thermocouple: aboveΦ0.45mm Applicable temperature range: -10¡ãC-60¡ãCTemperature measuring area: -10¡ãC-150¡ãCThe dimension of non-earthing type is as below:Outside diameter of metal sleeve: DWelding thickness: W=0.1D-0.8DInsulation thickness: A>=0.05DPosition of temperature measuring point: B=0.15D-1.5D 3.SleeveDiameter of sleeve: Φ3+-0.05Material: 1Cr18Ni9TiWall thickness of sleeve: above 0.3mm Type of sleeve: single Pressure proof: 5.0MPa4.Specification of compensation leadType of compensation lead: metal wrapped shield wireOuter diameter of element wire of compensation lead: 0.3¡Á7 pcs(wire rope)Coating form of the wire: 1.5-1.9mmApplicable temperature range: -10¡ãC-60¡ãCHeat resistant temperature: -10¡ãC-150¡ãCTemperature of compensation point: -10¡ãC-150¡ãC# The compensation point means the connection between thermocouple and compensationlead. Heat resistant temperature of core and wire coating: -10¡ãC-150¡ãC# If the temperature of the core and wire coating is above the heat resistant temperature,the elongation pipe could make it within the specified temperature range.The exposed length of the compensation lead on the slot is 2.2mm5.ConnectorThread dimension: PT1/86.OthersPt100 components shall be brazed with the outlet, and the connecting area shall beinsulated. 7.Checking itemVisual check, dimension check, insulation resistance check, temperature-rising check,pressure test, airproof test, voltage test, tensile test, impact test, thermoelectric test at about 80¡ãC.
