FA 500 – Dew point sensor with integrated display and alarm relay

The FA 500 is the right choice for maximum precision in Dew point measurements. Our sensor offers a wide range of Measuring ranges that are perfectly matched to the needs of different compressed air dryers. Rely on us for accurate results in every situation.

Monitoring a compressed air dryer is crucial to increase Energy efficiency, ensure product quality, prevent damage to machines, identify maintenance needs and realise cost savings. This contributes to the smooth functioning of compressed air systems in various Industrial applications.

Multiple display pages to show the Dew point and other measured variables such as relative Humidity and Temperature
Set alarm limit values for the relay, set the hysteresis
Scaling of the Analogue output 04…20 mA, switching to other measured variables
Input of the system pressure and the reference pressure for Calculation of reference dew points, e.g. Atmospheric dew point

Condensation-resistant sensor element
Pressure resistant up to 500 bar (special version)
Long-term stability and drift-resistant, therefore optimised calibration intervals
Measuring independent of gases, also suitable for other, non-corrosive gases
Fast adjustment time, especially in the event of moisture ingress
BSP or NPT thread
Protection class IP 65
Analogue output 4…20 mA and Modbus RTU (RS 485) interface, contact relay with limit value adjustable via buttons (max. 60 VDC, 0.5A)
Optional: Modbus TCP (Ethernet), Modbus TCP PoE (Ethernet) or M-Bus interface
Measured values available in various units, Pressure dew point [°Ctd], Temperature [°C], Rel. humidity [%rh], Abs. humidity [g/m³], Degree of humidity [g/kg], Humidity fraction V/V [ppmV/V], Water vapour partial pressure [hPa], Atmospheric dew point [°Ctd.atm]
