FA 550 V1.00

5 Device description

The FA 550 dew point sensor enables a reliable and long-term stable monitoring of the dew
point in industrial applications.

When mounting FA 550 into compressed air systems the pressure dew point (dew point
under pressure) up to 50 bar (in the special version up to 500 bar) is measured directly.
When mounting FA 550 in atmospheric conditions (ambient pressure) or in the flow off sector
(relaxed air) of compressed air systems the atmospheric dew point is measured.

Typical Application



compressed air plants (membrane- /adsorption dryers)



Residual moisture measurement / dew point measurement in gases such as:

Oxygen, nitrogen, argon, hydrogen, natural gas, biogas

…

Advantages

:



Extremely long-term stable



IP 67 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“



Analogoutput

o

1x 4..20mA (glav. not isolated,



Modbus RTU Interaface



Optional

o

2x 4..20mA galv. isolated

o

Ethernet or Ethernet PoE

o

MBus



Calibration on location and testing with CS control and calibration set (PC connection

set)

CS Instruments Service Software

With the CS Service Software incl. USB / Modbus Adapter the Modbus settings, the scaling of the
Analogue output and the assignment of the measurement values could be set.

-

Analogue output 4…20 mA scalable

- Switching between °Ctd,°Ftd, % RH, °C, °F, g/m³, mg/m³, g/kg, ppm, and so on
- Calibration and adjustment
