Resistance Temperature Detectors

Brand: Thermo-Kinetics
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.
Features
  • Rugged Construction 
  • Accurate and Stable Probes
  • General Purpose, Tip Sensitive, High Temperature and High Vibration Probes and Assemblies
  • 2, 3 and 4 Wire Configurations
  • General Purpose or Spring Loaded Mounting, with or without Thermowells
  • Nipple, Nipple-Union-Nipple or Bushing Extension Hardware
  • CSA Approved Assemblies for Hazardous Locations Averaging RTDs
  • Custom Configurations
  • Head Mounted Transmitter Options
