The RTD wire is typically platinum (Pt), nickel (Ni), or copper (Cu). The material has an accurate temperature–resistance relationship which is used to provide an indication of temperature. As RTD …

RTDs, or resistance temperature detectors, are sensors used to measure temperature. These sensors are the among the most accurate temperature sensors available, covering large temperature ranges.

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.

What are RTD temperature sensors? RTDs - or Resistance Temperature Detectors - are temperature sensors that contain a resistor that changes resistance value as its temperature changes. The most …

Three different length options, with both six- and nine-inch models covering a temperature range of -200 °C to 300 °C. One of the best features of this RTD sensor is that it conforms to the standard 385 …
