Temperature Sensors. Thermistors vs Thermocouples

Temperature sensors are important for everyday life, from working in industrial plants to preventing fires. Thermistors and thermocouples are two such temperature sensors. A thermistor is a thermally sensitive resistor that exhibits a continuous, small, incremental change in resistance correlated to temperature variations.

Difference Between Thermistor Thermocouple and RTD

Thermistor, thermocouples and RTD, which is an acronym for Resistance Temperature Detectors, are temperature measuring devices. While non-physicists may consider the three to be similar, they actually have significant difference between them. Thermistors differ from thermocouple and RTDs on account of material that they are made of, with thermistors being made of polymer or ceramic ...

Thermistor vs Thermocouple: Practical Comparison | Linquip

· Temperature Ranges – both NTC thermistors and thermocouples can operate within a wide range of temperatures, making them ideal for varying applications. An NTC thermistor should be used between -50 to 250 °C, whereas a thermocouple should be used between -200 °C to 1750 °C. Accuracy of Sensor – A thermocouple, when compared to an NTC thermistor, has lower accuracy. Thermocouples …

How to Identify a Thermocouple, RTD & Thermistor

Thermocouples are the easiest temperature sensor to identify. A thermocouple probe has two wires identified by a colour code. Thermocouples usually come in a 2-wire construction. Sometimes they employ a 3-wire construction if a ground or shielding wire is present. They have very low resistance (compared to RTDs and thermistors.) Depending on ...
