Error due to change of pressure (above 800hPa abs.)
< 1% of smallest range per 10hPa
• Accurate and long term stable thermal conductivity measurement • High sensitivity e.g. 0-0.5Vol.% H2 in N2 range; Low noise <10ppm H2 in N2 • Precise linearization for the gas mixtures as H2, He, CO2, CH4 in N2 or Ar and N2 in Ar on board • Customized linearization with polynomial up to sixth order • Multi Gas Mode allows sequential indication of up to 15 binary mixtures • Isolated 4-20mA output, expandable; free set of start and end within 100 Vol.% range • Classic 2-point calibration or simple one-gas calibration • Free set of display indication (ppm or Vol.%) at a resolution up to 1ppm • Cross sensitivity compensation by feed in of external signal and internal calculation • Fast response with a T90-time of less than 1 sec (depending on flow rate) • Pressure proof (20bar) and vacuum leak tight stainless steel (LF316i) gas duct • Three isolated relays for indication of alarms and instrument status • RS 232 excess to all values and parameters • Digital output with 1ppm resolution over the whole 100Vol.% rangePC-based service program simplifies all settings, linearization and calibration • Small and robust transmitter in Al-housing for field use (protection class: IP65) • Dimensions: Width 145mm, Height 80mm (without connectors), Depth 85mm • Power supply 18V to 36V DC / 700mA
