ESMWZP Industrial RTD Temperature Sensor PT100 price
Introduction
Pt100 is a platinum thermal resistance whose resistance is proportional to the change in temperature. The relationship between the resistance of PT100 and temperature is: when the temperature of PT100 is 0 °C, its resistance is 100 ohms, and its resistance is about 138.5 ohms at 100 °C. Its industrial principle: When the PT100 is at 0 degrees Celsius, its resistance is 100 ohms, and its resistance will increase at a constant rate as the temperature rises.
The resistance value and temperature of the metal thermal resistance can generally be expressed by the following approximate relationship, that is,
Rt=Rt0[1+α(t-t0)]
Where Rt is the resistance at temperature t; Rt0 is the corresponding resistance value at temperature t0 (usually t0 = 0 °C); α is the temperature coefficient. The relationship between the resistance and temperature of the semiconductor thermistor is
Rt=AeB/t
Where Rt is the resistance at a temperature of t; A, B depends on the constant of the structure of the semiconductor material.
Product specifications are as follows:
Index number: PT100
Probe size: 5mm (diameter) * 50mm (length)
Line length: 1-5m
Wire: Silicone wire
Core: Two cores (ie two-wire system, customers who need three-wire system can contact the seller)
Temperature resistance: -60-260°
Special attention:
In order to meet your temperature measurement requirements, the silicone lead is -60~260 degrees temperature resistant, the imported PVC lead is 108 degrees (domestic PVC temperature resistance 80 degrees), please pay attention to the buyer.
The lead wire is required to be four-wire, which can meet the wiring requirements of three-wire and two-wire systems at the same time. (Two wires of the same color can be used as one wire during the wiring process)
