Technical Specifications
Applications
- Extractive gas analysis
- Quality and process monitoring
- Contiuous concentration determination of single gas components 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 to 20 mA
- Easy calibration with covered push buttons
- 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 two heating elements and a temperature sensor at constant 63?°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 two 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, or in a mixture of O2 and N2
