ATEX / IECEx Spring Loaded RTD Pt100 Sensors

with a choice of Terminal Heads

These spring loaded flexible mineral insulated platinum resistance thermometers utilise, as standard, detector elements with a resistance of 100 ohms @ 0°C and a fundamental interval of 38.5 ohms to IEC 60751. The threaded flameproof extension is ideal for installation in thermowell pockets and where good contact with the process is required.
  • Available in a wide range of protection concepts for Zones 0, 1 & 2 use. See table below for details
  • Temperature classification T6-T1, see here for stand-off requirements
  • Available in B, A, 1/3, 1/5 and 1/10 grade accuracies
  • Sheath diameters from 0.188" to 0.313"
  • Spring loaded RTD Pt100 insert with wide choice of process connections
  • Wide operating temperature range of -148°F to +1112°F
