Description
Resistance Temperature Detectors (RTDs) are used for industrial temperature measurements where high accuracy and long-term stability are required.
The 100 ohm platinum element is the most common for industrial applications.
The 3-wire lead configuration is used for industrial temperature measurements and provides adequate compensation for leadwire resistance.
The 4-wire arrangement fully eliminates all leadwire effects and is used in applications where high accuracy is required.
