Relative moisture sensor AquaXact 1688

in-lineModbusProfibus

A rugged ultra-thin film Aluminum Oxide moisture sensor, the AquaXact 1688 enables the measurement of moisture in a wide variety of gas phase process applications, such as glove boxes, air separation units, regenerative skid dryers, combustion, and instrument air, with no calibration required after dry-out. High performance Versatile Simple maintenance and reduced ongoing costs The AquaXact 1688 is a rugged, ultra-thin film Aluminum Oxide (Al2O3) moisture sensor that enables fast and accurate dew point/ppm H2O measurements of moisture in a wide variety of gas phase process applications. Not only is it a standalone 4-20mA transmitter, but it is also able to be connected to the SERVOPRO MonoExact DF310E, AquaXact 1688 digital controller and SERVOPRO MultiExact 4100. These devices provide a high-clarity color touchscreen display, alarms, relays and advanced communication protocols including RS485, Modus RDU, Modbus TCP/IP and PROFIBUS Field-replaceable sensor tip in a robust casing The AquaXact 1688’s Al2O3 thin film sensor tip can be replaced by the user and the associated calibration file loaded into the transmitter using a digital controller, eliminating the need for return-to-factory calibrations. The sensor element is NIST-traceable and field replaceable, for hassle-free continuous operations. Stainless steel, weatherproof casing enables operation in ambient temperatures ranging from -10 to +70°C (14 to 158°F).
