2 Wire Rtd Temperature Sensor
2 wire rtd using the 2 wire method the two wires that provide the rtd with its excitation current and the two wires across which the rtd voltage is measured are the same.
2 wire rtd temperature sensor. Rtd sensor overview thermometrics corporation manufactures a complete line of temperature detectors including resistance temperature detectors. Rtd sensors wiring colour codes and configurations details of rtd wiring configurations for 2 wire 3 wire and 4 wire rtd sensors application methods and equipment rtd as with thermocouples rtd outputs measuring temperature change are small we are looking at less than 0 5 ohms per c for an iec standard device. Difference between 2 wire rtd 3 wire rtd and 4 wire rtd s rtds resistance temperature detectors are offered with 2 3 or 4 lead configuration. A 2 wire rtd configuration is the most useful with high resistance sensors or in applications where a great deal of accuracy is not required.
Rtd sensor overview thermometrics corporation manufactures a complete line of temperature detectors including resistance temperature detectors. The best configuration for a specific application depends on a number of factors however the sensor configuration must match with transmitter otherwise leadwire resistance cancellation circuitry. 4 1 out of 5 stars 51. 3 wire rtd connections the 3 wire rtd configuration is the most commonly used rtd circuit design and can be seen in industrial process and monitoring applications.
