ATEX Spring Loaded RTD Pt100 Sensors

with a choice of Terminal Heads

ATEX Spring Loaded RTD Pt100 SensorsSend Enquiry Data Sheet Request Info


Also available with IECEx Approval
These spring loaded flexible ATEX approved mineral insulated RTD Pt100 sensors 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 -328°F to +1112°F
  • UKAS calibration available.
