The measuring range of -20...50 °Ctd makes the dew point set DS 52 with alarm the
ideal dew point monitor with analogue output 4...20 mA.
The dew point sensor FA 415 is extremely long-term stable and can be installed
and removed quickly and easily under pressure by means of the screwable measuring
chamber including quick coupling. The dew point set is supplied ready for plug-in,
i. e. everything is completely wired. The alarm values can be freely adjusted.
