The AQUATRACE® ATT520V is our new P2O5 trace moisture analyzer for ppmV | ppbV for inert and combustible gases. Our ATT520 measures the volume-related moisture content and approximately converts this value into the corresponding dew point temperature. Suitable for process and industrial moisture measurement, the measuring system is also available with a limit alarm relay and status relay. The large 1.8" TFT display (optionally available) visualizes the measured value in an easy-to-read manner. If the range is exceeded, the display color changes to flashing red. In addition to a 4-20mA analog output, the analyzer also has an RS232 interface, which is used to read out the measured value but also for adjustment to local conditions. A watchdog (optional) monitors the electronics and a status relay (optional) sends the functional status to the control room.
5 practical standard variants available:
• By-Pass-Solution with 20Nl/h standard measuring chamber
• DN25KF/DN40KF flange adapter for inline-measuring
• G1/2-Thread for inline-measuring
• electronics with separate sensor (in the above variants: standard chamber | DN25KF | DN40KF | G1/2")
• Intrinsically safe variant: Ex II 2G Ex Ia IIC T4 Gb (using a ZENER-barrier)
Particularly suitable for the following sectors:
• glove-boxes | isolators
• vacuum technology
• Plasma, sintering and soldering furnaces
• Technologies with protective gases (welding; soldering; thermal treatments, etc.)
• coating plants
Further advantages of our proven P2O5 residual moisture measurement method:
• No drifting
• No follow-up costs as maintenance-friendly
• Offset | Span | Bases possible via digital interface
• Dry to wet: T90 < 5 sec; Wet to dry: T90 < 15 min
• Significantly higher resolution of 0.01ppm in the 0-500ppm range and 1ppb in the 0-20,000ppb range
• Further improved response
• Analogue output and digital communication via RS232
• Optional: limit value relay, watchdog, large 1.8" TFT display, Ex(i) version
