Dew point sensor in a durable die-cast aluminum housing — FA 550

Description

The FA 550 sensor is the ideal solution for measuring dew point temperature outdoors or in harsh industrial conditions. It provides reliable dew point control with long-term stability in industrial applications.

When the FA 550 sensor is installed in compressed air systems, the dew point under pressure (pressure dew point) up to 50 bar (up to 500 bar in special versions) is measured directly. When the sensor is installed in atmospheric conditions (at ambient pressure) or in the air outlet zone (at atmospheric pressure) from compressor units, the atmospheric dew point is measured.

Special Advantages

• Robust sealed die-cast aluminum housing, protection class IP 67
• Signal relay threshold value adjustable via buttons on the display (max. 60 V DC, 0.5 A)
• Analog output 4...20 mA
• Optional: two analog outputs 4…20 mA, e.g., for dew point temperature and ambient temperature
• Extremely high long-term stability
• Fast response time
• Operating pressure up to 500 bar (optional)
• New: Modbus RTU interface
• New: Ethernet interface (optional)
• New: higher signal resolution thanks to improved electronics
• New: on-site sensor diagnostics using portable devices or CS Service Software
• Via Modbus, the following values are available: dew point temperature under pressure [°C dp], temperature [°C], relative humidity [% RH], absolute humidity [g/m³], volumetric moisture content [ppm V/V], saturated vapor pressure [hPa], atmospheric dew point [atm. °C dp]

Applications

• Measurement of compressed air dew point temperature after adsorption / membrane / refrigeration dryers
• Measurement of residual moisture / dew point of various gases such as oxygen, nitrogen, argon, hydrogen, natural gas, biogas, etc.
