The FA 500 dew point sensor is an advanced monitoring tool tailored for effective and reliable measurement in refrigeration and adsorption dryers in compressed air systems.
Designed with an integrated display, it provides immediate visualization of dew point levels and can be adjusted via keypad to suit specific requirements. The alarm functionality can trigger alerts at key thresholds to maintain operational safety and efficiency.
Capable of handling pressures up to 7251 psi in specialized versions, the FA 500 ensures robust performance even under extreme conditions. The sensor offers an analog output that ranges from 4 to 20 mA, allowing for precise measurements from -112 to 68 °Ftd.
Enhanced Communication Facilities
The unit comes equipped with a Modbus-RTU interface, ensuring seamless integration with existing monitoring systems. The upgraded electronic evaluations enhance the resolution of the sensor signal, improving the overall accuracy and reliability of the measurements.
For in-depth analysis and on-site diagnostics, the FA 500 can be connected to CS Service software, allowing for comprehensive monitoring and configuration tailored to user-specific demands.
Additional Outputs
In addition to the standard dew point output you'll get via the 4-20 mA analog output, you can also get the following output via modbus:
- Pressure dew point [°Ftd]
- Temperature [°F]
- rel. humidity [% RH]
- abs. humidity [g/m³]
- Degree of humidity [g/kg]
- Moisture content V/V [ppmV/V]
- Partial vapor pressure [hPa]
- Atmospheric dew point [°Ftd.atm]
