Dew point FA 550 dew point sensor in robust die-cast aluminium housing The FA 550 is ideal for outdoor dew point measurements or rougher industrial environment Special features: • Robust, waterproof die-cast aluminium housing, IP 67 • Alarm relay - limit value adjustable via buttons (max 60 VDC, 0.5 A) • 4...20 mA analogue output • Optional: 2 pieces 4 ... 20 mA analogue output e.g. for dew point and temperature • Extremely stable in the long term • Quick adaption time • Pressure-resistant up to 500 bar (optional) • NEW: Modbus-RTU interface • NEW: Ethernet interface (optional) • NEW: Higher resolution of sensor signal due to the improved evaluation electronics • NEW: Sensor diagnosis on site with a portable device or CS Service Software • Readable via Modbus: pressure dew point [° Ctd.], temperature [° C], rel. humidity [% RH], abs. humidity [g/m³], degree of humidity [g/kg], moisture content V/V [ppmV/V], partial vapour pressure [hPa], atmospheric dew point [° Ctd.atm] APPLICATON: • Dew point measurement in the compressed air after adsorption dryers/membrane dryers and refrigeration dryers • Residual moisture measurement / dew point measurement in gases such as: oxygen, nitrogen, argon, hydrogen, natural gas, biogas ... Easy operation via the keys on the display The integrated display shows the dew point in big figures as well as further humidity parameters on two more display pages. The arrow key can be used to scroll between the display pages. The alarm threshold value for the integrated relay can be freely entered via the keys. In addition to the alarm threshold, the hysteresis can also be freely entered. The 4…20 mA analogue output can be scaled freely or also allocated to one further parameter, e. g. g/m³. After entering the system pressure of the compressed air system and the reference pressure (atmospheric pressure), the sensor can also calculate back to the atmospheric dew point from the measured pressure dew point if desi
