FTC110-TRA

Thermal Conductivity Detector

Applications

  • For extractive gas analysis
  • For quality and process monitoring
  • For contiuous concentration determination of single gas components like e.g. H2, CO2, O2, He
  • For the H2-measurement at heat treatment in the metal industry
  • For the H2-measurement in miniplants

Benefits

  • Precise and long-term stable thermal conductivity measurement
  • Independent of gas flow and gas pressure
  • High sensitivity independent of the ambient temperature
  • Fast response time (T90 approx. 1 s)
  • Pressure resistant gas paths out of stainless steel (10 bara)
  • Robust tight aluminium housing (IP65)
  • Small dimensions
  • Linear signal output 4-20 mA
  • Easy calibration with 2 potentiometers
  • Factory configuration and calibration

Features

  • Based on micromechanic silicon chip
  • Detector mounted in a stainless steel housing
  • Stainless steel housing and electronic mounted in a sealed aluminium housing
  • Operation of the detector with 2 heating elements and a temperature sensor at constant 60 °C
  • Gas concentration corresponds to required compensation energy, depending on cooling of the chip due to varying thermal conductivity
  • Especially good measuring results are achieved under following conditions:
    • at binary gas mixtures, e.g. CO2 in N2, O2 in Ar or H2 in N2
    • if only 2 gas components at multi component mixtures vary in concentration, e.g. CO2 in air
    • if the measured component has a significantly different thermal conductivity than the remaining gas components, e.g. H2, He, CO2 in air or impurities in H2
