2-Wire, 3-Wire or 4-Wire RTDs – What’s The Difference?

    The difference between 2-wire, 3-wire, and 4-wire RTDs (Resistance Temperature Detectors) lies in the method of connecting the RTD to the measurement instrument and how each configuration compensates for lead wire resistance. Here is an explanation of each configuration: 2-Wire RTD Configuration: Two wires connect the RTD element to the measurement device. Advantages: […]

Which is better? thermocouple, thermistor or RTD

The choice between a thermocouple, thermistor, or RTD (Resistance Temperature Detector) depends on the specific application requirements, including the temperature range, accuracy, response time, environment, and cost. Here is a comparative overview of these temperature sensors: Thermocouples Advantages: Wide Temperature Range: Can measure very high and very low temperatures (-200°C to +2500°C, depending on the […]
