Relative humidity transmitter HLX31

absolutewall-mountduct-mount

The optimal hardware structure of the humidity transmitters HLX31 for varying applications is achieved by combining various standard mechanical and electronic modules. Besides relative humidity and temperature following quantities are also measured: • absolute humidity • dewpoint temperature • frostpoint temperature • specific enthalpy • wet bulb temperature • water vapour partial pressure • mixture ratio By selecting a suitable housing version the humidity transmitter HLX31 can be used for the entire range of humidity measurement applications: • Model A: wall mounting • Model B: duct mounting • Model D: remote sensing probe for -40...180°C • Model E: remote pressure tight sensing probe for 0,01...15 bar
