Thermistor vs RTD Temperature Measurement Accuracy ...

Temperature transmitters can have spans from °C (30°F) to 555°C (1,000°F) and low, 4mA temperatures, from -150°C (-238°F) to 482°C (900°F). For an extra fee, RTDs and transmitters can be matched to have measurement errors of °C (°F) across the span. So what sensor is better, an RTD or a Thermistor? It depends.

Thermistors are commonly used for sensing air and liquid temperatures in pipes and ducts, and as room temperature sensors. The term "thermistor" evolved from the phrase thermally sensitive resistor. Thermistors are temperature sensitive semiconductors that exhibit a large change in resistance over a relatively small range of temperature.

A Basic Guide to Thermocouple Measurements

Thermocouples are common temperature sensors used in a wide variety of commercial and industrial applications. While slightly less accurate than resistance temperature detectors (RTDs), thermocouples cover a wide temperature range, are self-powered, and have a fast response time. Their simple construction make them inexpensive and durable.
