AeroX Stream 200

For an Automated Weather Observing System (AWOS), the Field Data Collection Unit (FDCU) serves as a critical juncture between the sensors out in the field and the data processing unit (DPU). Thus, the FDCU, named AeroX™Stream 200, collects all the data from the various meteorological sensors and sends the data to the DPU for processing and distribution. Furthermore, the AeroX Stream 200 manages the power distribution to each of these sensors and provides a battery backup in the event that the mains power goes out.

Components of the AeroX Stream 200 include a stainless-steel enclosure, data logger, AC to DC power supply, backup battery, transient protection, circuit breakers, maintenance port, barometer(s), data communications, and optional heating. The AeroX Stream 200 is built predominantly of commercial-off-the-shelf (COTS) components, and many of the components are attached via a DIN rail or on the gridded backplate for ease of manufacturing, maintenance, and service.

With the Campbell Scientific data logger at its core, the AeroX Stream 200 has the flexibility and capacity to add both analog and serial sensors that are new or provided by other manufacturers. This sensor flexibility facilitates platform expansion if needs or budgets change.

Power is provided from a 110 to 240 Vac, 45 to 65 Hz, single-phase power source. This AC power flows through a series of transient and surge protections to a 24 Vdc power supply that distributes power to the sensors, communication peripherals, data logger, and battery. These different levels of transient protection defend the system against lightning strikes and unexpected power surges. In the event that the airport’s mains power goes down, the AeroX Stream 200 contains an uninterruptable power supply (UPS) system that can provide three to six hours of backup power, depending on sensor and communication configuration. This estimate is based on a full serial sensor load (12 to 13) with no heaters. For many applications, this full load will not be used, and the backup power will be longer.
