CS Instruments FA 500 Dew Point Sensor with Display & Relay

Description

Monitoring a compressed air dryer is critical to maintaining product quality and achieving significant cost savings. The CS Instruments FA 500 Dew Point Sensor simplifies this process by combining advanced sensor technology with a user-friendly interface.

The standout feature of the FA 500 is its intelligent evaluation electronics. Users can view distinct display pages that show not only the dew point but also other relevant variables such as relative humidity and temperature. This eliminates the “blind spots” often associated with simple analog sensors.

Furthermore, the FA 500 allows for the input of system pressure and reference pressure values. This capability enables the sensor to calculate and display reference dew points (e.g., atmospheric dew point) in real-time, providing a more comprehensive analysis of your system’s performance. With its integrated alarm relay, you can set specific threshold values and hysteresis, ensuring that your team is instantly alerted to any moisture issues before they impact production.
