4 Wire RTD Pt100
A 4 Wire RTD provides a Higher Level of Temperature Accuracy as compared to the 2 and 3 wire RTD configurations. This is due to the fact the 4 Wire configuration eliminates the potential differences in circuit resistance resulting from a variation in lead wire length, diameters and materials.  
  • 4 Wire RTD designs were historically utilized in laboratories and research centers 4 Wire RTD Designs due to the higher cost of the sensor and special instrumentation to accept a 4 wire input.
  • Increased Utilization of the 4 Wire RTD design is occurring throughout industry. Cost has reduced and availability for the sensors and instrumentation has increased. The value from improved temperature accuracy has enhanced product quality, efficiency and new product development.
  • RTD Connectors with 4 Wire capabilities has also influenced the ongoing adoption of this configuration. The circular connector technology such as the M12 design and other circular connectors along with miniature connectors utilized in in automation, electronic, aerospace and automotive are being increasing utilized in other industries as well. 
  • Pt100 (platinum 100 ohm) and Pt1000 (platinum 1000 ohm) resistance temperature devices are the most commonly used design with the 4 Wire configuration. 
  • Temperature Operating range for a 4 Wire RTD is the same as the 2 or 3 wire configurations, meaning -320°F to 1,562°F (-196 to 850°C) depending on the design selected.
