Industrial Thermal resistances are also called Thermal Resistors. It can measure and regulate the temperature of liquid, vapor and gas media as well as solid surfaces in the range of -200~650℃. If equipped with corrosion-resistant protective tube. Can also be used in corrosive media.

Industrial Thermal resistances are divided into platinum resistors and copper resistors according to materials, as well as less commonly used indium resistors, nickel resistors, etc. It is generally composed of temperature sensing components, transition leads, insulating tubes, protective tubes, junction boxes, installation fixtures and other parts. Usually used with display instruments, recorders and electronic regulators.

RFQ Temperature Sensors

We at Sino-Inst mainly produce two major types of assembly thermal industrial thermometers: Pt100, Pt10 platinum thermal resistance and Cu50, Cu100 copper thermal resistance.

Technical Parameters:

Thermal Resistor Category	Resistance value	Temperature measurement range	Accuracy level and tolerance (℃)
WZP Platinum Resistance	Pt100	-200~500℃	Grade A: ±(0.15+0.002︱t︱) Grade B: ±(0.30+0.005︱t︱)
	Pt10	-200~650℃
WZC Copper Resistance	Cu50	-50~150℃	±(0.30+0.006︱t︱)
	Cu100

Note:

︱t︱ is the value of humidity measured by the hygrometer;
Level A accuracy is not suitable for secondary systems, and the thermometer should be calibrated once a year.

Wiring instructions

Description:
The two-wire system is suitable for places where the lead wire is not long and the temperature measurement accuracy is low.

Description:
The three-wire system can reduce or eliminate the effect of resistance on ambient temperature and is used for industrial measurements with general accuracy.

Description:
Use two wires at both ends of the resistor to provide a constant current source I for the resistor. A voltage drop occurs on the resistor. Use the other two wires to connect the display instrument for measurement. This completely eliminates the influence of the wire resistance on the ambient temperature. Mainly used for high-precision temperature measurement.
