Robust dew point sensor for compressed air and gases The FA 550 is ideally suited for outdoor dew point measurement and reliably determines dew points even under harsh industrial conditions. Application examples: — Dew point measurement in compressed air systems after adsorption dryers, membran dryers or refrigeration dryer — Residual moisture measurement and dew point measurement in gases such as: oxygen, nitrogen, argon, hydrogen, natural gas, biogas… Special features of the dew point sensor FA 550: — Robust, waterproof die-cast aluminum housing, IP 67 — Alarm relay — limit value adjustable via buttons (max 60VDC, 0.5 A) — 4 … 20 mA analog output — Optional: 2 pieces 4 … 20 mA analog output e.g. for dew point and temperature — Extremely long-term stable — Fast adjustment time — Pressure resistant up to 500 bar (optional) — NEW: Modbus RTU interface — NEW: Ethernet interface (optional) — NEW: Higher resolution of the sensor signal due to improved evaluation electronics — NEW: Sensor diagnosis on-site with handheld 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 / m3], moisture content V / V [ppmV / V], Partial vapor pressure [hPa], atmospheric dew point [° Ctd.atm]
