Summary: WZ series of industrial thermal resistance as a temperaturesensor,
usually is with the temperature transmitter, and the regulator,
andassorted instruments process control systems for the direct
measurement orcontrol of the production process -200C -500C within
the liquid, steam andgas MEDIA and the solid surface temperature. Thermal resistance is the use of substances in the
temperaturechange itself also with the resistance changes to
measurement of temperature.When measured in the temperature-body
whose existence, the measured temperatureis the temperature of the
components of the media in the averagetemperature. Despite the appearance of various thermal resistance vary,
theirbasic structure is broadly similar to felt normal temperature
components,insulation casing to protect tubes, and wiring boxes,
and other major components
Features:
High temperature measurement accuracy;
Thehigh mechanical strength, good pressure performance;
High quality filmresistor element, reliable and stable properties.
Principle:
Thermal resistance is the use of substances in the temperature
changes, asalso its resistance changes to the measurement of
temperature. When the resistance change, the instrument will work
showedresistance value corresponding to the temperature. The main technical parameters: Products implementing the standards
IEC584
IEC1515 GB/T16839-1997 JB/T5582-91 Insulation resistance at normal temperature: Thermal resistance at ambient temperature for 15 - 35C,relative
humidity of less than 80%, test voltage of 10 - 100V (DC) between
theelectrode and the jacket pipe insulation resistance> 100
megohms. Temperature measurement and Tolerance: Model | Indexing, | Temperature measurement range | Precision grade | Tolerances | WZP | Pt100 | -200-+500 | Grade A | ± ( 0.15+0.002) ltl | Grade B | ± ( 0.30+0.005) ltl | WZC | Cu50 ? Cu100 | -50-+100 | --- | ± ( 0.30+0.005) ltl |
