Dew point meter FA 500
The FA 500 (from -80 to 20 °Ctd) is the ideal dew point meter with integrated display and alarm relay for refrigeration, membrane and adsorption driers.The FA 500 dew point sensor enables a reliable and long-term stable monitoring of the dew point in industrial applications from -80 to +20 °C dew point. The FA 500 features improved stability.
When mounting FA 500 into compressed air systems the pressure dew point (dew point under pressure) up to 50 bar (in the special version up to 350 bar) is measured directly. When mounting FA 500 in atmospheric conditions (ambient pressure) or in the flow off sector (relaxed air) of compressed air systems the atmospheric dew point is measured.
Advantages of Dew point sensor FA 500
- Dew point sensor for very low dew points down to -80 °Ctd
- Extremely long-term stable due to internal automatic calibration
- IP 65 housing grants a reliable protection in extreme industrial conditions
- Very fast response time
- Installable in the dryer by means of G 1/2" thread, optional UNF 5/8” or NPT ½”
- High accuracy of ± 2 °Ctd
- Calibration on location and testing with CS control and calibration set (PC connection set)
