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
