  • Page 5: Intended Use

    Intended Use Intended use The FA 550 dew point sensor is intended for measuring the dew point or the pressure dew point in clean, dry and oil-free gases and compressed air. It is the responsibility oft he user whether the instrument is suitable for the selected application.

  • Page 6: Device Description

    Intended Use Device description The FA 550 dew point sensor enables a reliable and long-term stable monitoring of the dew point in industrial applications. When mounting FA 550 into compressed air systems the pressure dew point (dew point under pressure) up to 50 bar (in the special version up to 500 bar) is measured directly.
