3 wire RTDs have a third wire that provides a measurement of the resistance of the lead wire and subtracts this resistance from the read value. This correction compensates for the effect of the resistance of the long lead wires on the temperature measurement and results in improved accuracy.
Key Features
3-wire design for lead-wire resistance compensation
Improved accuracy over long distances
Rugged SS316 sheath for corrosion resistance
Compacted MgO insulation for high durability and fast response
Fixed 1/2″ (M) process connection for easy installation
Suitable for –50°C to 400°C temperature applications
Supplied with 2-meter TF/TF cable
Applications
Industrial temperature monitoring from –50°C to 400°C
Process piping and equipment temperature measurement
