Product Description Product Overview:WZ Thermal Resistance as the sensor for measuring temperature, often matches with display instrument, recorder and electronic regulator for use. It can directly measure the surface temperature of the liquid, steam and air medium from -200oCto 500oC as well as the surface temperature of solid during productive process.Features:·Imported temperature-sensing element stable and reliable function·High machanical strength, good pressure resistance·High measuring accuracy·Compensating wire needless, convenient and economicalParameters:Temperature Range and AccuracyThermal resistance TypeThermal ResistanceAllowable deviation△t oCWZP Type platinum resistorPt100B Grade ±(0.3 or+0.005t)A Grade ±(0.15 or+0.002t)WZC Type Copper ResistanceCu50-50~100oC ±(0.30+6.0×10-3t)Remark: The "t" in formula is Absolute value of measured temperature of temperature sensing element.Thermal Response TimeWhen there is a step change in temperature,The time required for the output of the thermal resistance to change to 50% of the step change, It's called thermal response time, with T0.5 said.Protective tube diameter(mm) Protective tube MaterialThermal response time t0.5 (s)Platinumthermal resistanceΦ121Cr18Ni9Ti30~90Φ1630~90Taper protective tube90~180Copper thermal resistance Φ121Cr18Ni9Ti<180Thermal resistance Nominal PressureGenerally refers to the external pressure (static pressure) that the protective tube can withstand at this working temperature.The allowable nominal pressure is not only related to the material, diameter and wall thickness of the protective tube, but also to its structure, installation method, placement depth and the flow rate and type of the measured medium.Thermal resistance Minimum Placed-depthlmin=l +15Dlmin-Minimum Available Placed-depthL -Temperature sensing element lengthD-Outer diameter of protective pipeInsulation ResistanceThe test voltage of insulation resistance at room temperature can be 10 ~ 100V dc arbitrary value, the ambient temperature in the range of 15 ~ 35oC, the relative humidity should not be more than 80%.Cold insulation resistance shall be not less than 100 m Ω.Structure Drawings:Ordering Guide: Item NO.Type WZThermal Resistance CodeType ofThermal Resistance PPt100CCu50 CodeOutput Signal N/ASingal2Double CodeInstallment Way 1No fixing device2Fixed thread3Flexible Flange4Fixed Flange CodeJunction Box 1Simple Type2splash-proof3Water proof4explosion-proof Type7Aviation Plug in CodeDiameter of Protective Tube 016mm112mmOtherMark with Words CodeMaterial of Protective Tube S4SUS304S6SUS316L CodeType of Measuring Terminal 2Two-wire3Three-wire CodeCustomizatioonNIntegration CNC, No Weldingll=Insertion Depth(mm)LL=Length of Protective Tube(mm)TTemperature Range T=(t1,t2)For Example: WZP2-230-S4-3 l=100 L=250 T=(0~300)oCRelated Products:Certification:FAQ:1.
