Frequently Asked Questions (FAQs)

1. What are the types of temperature transducer?

There are four types of temperature sensors that are most commonly used in modern-day electronics: thermocouples, RTDs (resistance temperature detectors), thermistors, and semiconductor based integrated circuits (IC).

2. Where are temperature transducers used?

are used in the heating, ventilation and air-conditioning sectors as well as in any other place where it is required to test the production process temperature. Temperature transducers vary depending on the measuring principle. Different temperature transducer models are available.

3. How does a transducer measure temperature?

One junction is kept at a constant temperature called the reference (Cold) junction, while the other the measuring (Hot) junction. When the two junctions are at different temperatures, a voltage is developed across the junction which is used to measure the temperature.

4. What is a RTD transducer?

An RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time.
