Tank Thermometer - Mineral-insulated

• Mineral insulated thermometer for temperature measurement in insulation and concrete surroundings e.g. liquid gas tanks and LNG tanks e.g. liquid gas tanks, LNG tanks and thermal energy storage tanks.
• Measuring temp. range: -200°C to +100°C.
• The measuring element is glass encapsulated platinum elements according to EN60751.
• Protective sheath of AISI 316L filled with compressed MgO powder. Sensor tip Ø6 AISI 316L.
• 24 AWG PTFE
• Response time (mean values) measured at velocities in:
   water w. 0.4 m/s: t0.5 = 6.4 sec. - t0.9 = 27 sec.
• Recommended measuring current: 1 mA (max. 2 mA).
• Approvals: Ex ia IIC T6 Ga
  FM13ATEX0019X
  IECEx FME 13.0003X
  DNV-GL EU RO MR

To achieve the highest accuracy we recommend the 4 wire calibrated version.
Each calibrated sensor is supplied with a certificate stating its own individual coefficients Ro, A, B and C to substitute the standard coefficients in the EN60751 platinum curve. By use of the coefficients the uncertainty of the sensor will be <=20 mK in the range -195 to 100 °C. The transmitter will represent the major part of the total system uncertainty.
