Testermeter-PIDMAXWELL OEM PT100 RTD Thermometer Probe Multi-Strand Heat Sensor with 3 2 4 Wires Temperature Sensors
Features
As a temperature sensor based on the platinum resistance (RTD) principle, its core characteristics stem from the resistance-temperature effect of platinum material: the standard resistance value at 0℃ is 100Ω, and the resistance value changes in a precise linear relationship with temperature, following the international standard IEC 60751 formula \(R_t = R_0(1 + at + bt^2)\), ensuring the reliability of full-scale measurement. The accuracy levels cover Class A and Class B: Class A accuracy: The error range is ±(0.15 + 0.002×|t|)℃, suitable for high-precision scenarios such as scientific research experiments and precision instrument calibration; Class B accuracy: The error range is ±(0.3 + 0.005×|t|)℃, meeting the routine requirements of industrial process control, environmental monitoring, etc. It has excellent long-term stability, with an annual drift of ≤0.05%, supporting long-term operation without calibration. |
