The AQUATRACE® ATT520Ex (d) model is perfectly for use in potentially explosive areas
With our ATT520Ex we present our new ATT520 trace moisture transmitter in a flameproof enclosure. He works on the basis of our proven P2O5 sensors and can therefore be used in all gases, including chlorine gas. The large number of design variants enables precise adaptation to your task.
In the range of 0 - 500 ppmV | 0 - 20,000 ppbV (depending on the measuring range variant) you get an analog output signal of 4 - 20 mA or 0-10V. The transmitter can be adapted or configured to the specific application conditions via a serial interface.
