The Magellan 420 Weather Station combines a rugged multi- parameter weather sensor with an internal compass for critical weather monitoring with automatic wind direction alignment.
The 4-20 mA signal outpt interfaces to PLC, DCS and SCADA systems.
(Modbus/OPCcommunication is available with the Weather MicroServer monitoring any CWS weather station.)
Additionally, real time monitoring, data logging, and graphing are available with a stand-alone Weather Display Console and/or Weather Master Software. The Weather MicroServer can also be connected to offer Internet-ready data as well as additional industrial protocols.

The Magellan 420 Weather Station incorporates the following sensors in a compact, rugged, metal all-in-one sensor head. Click to expand for specific sensor and measurement details.
A unique folded-path, low power sonic anemometer operates on the principle that the speed of the wind affects the time it takes for sound to travel from one point to a second point. If the sound is traveling in the direction of the wind, then the transit time is decreased. If the sound is traveling in a direction opposite the wind, then the transit time is increased.
The wind sensor has no moving parts, which makes it maintenance free. The measurement range for wind speed is from 0 to 134 mph (0 to 60 m/s) and for wind direction from 0 to 360°.
Barometric pressure, temperature, and humidity sensors are housed in a powder-coated metal radiation shield.
Barometric pressure is measured with a stable transducer using nano-technology, yielding a linear and repeatable sensor with low hysteresis. The piezoresistive pressure sensor module is mounted on a small electronic circuit board.
A microcontroller controls the operation of the sensor and the data interface. The microcontroller polls the pressure sensor module once per second for the barometric and ambient temperature. The raw readings are temperature corrected by the microcontroller.
Temperature measurement uses a precision triple-element thermistor. This provides highly accurate and stable readings.
Humidity is measured with a capacitive polymer sensor. This construction provides excellent resistance to wetting, dust, dirt, oils, and common environmental chemicals.
The internal compass module is low power and compact. It employs a pair of magneto-inductive sensors which change inductance with varying magnetic field strengths, to sense the Earth's magnetic field.
The microprocessor measures the output of the internal compass and then corrects wind direction data for the orientation of the sensor. The output of the wind direction is relative to Magnetic North. A user-programmable value of Magnetic Declination may be entered through terminal mode to enable output relative to True North rather than Magnetic North.
The optional tipping bucket electric rain gauge is composed of a complex spun collector funnel with a knife edge that diverts the water to a tipping bucket mechanism. For each tip, a magnet causes an electronic pulse that is recorded. The rainfall sensor is completely automatic - spent water drains out of the bottom of the housing, hence, the instrument requires no servicing.
The rain gauge comes with a 50-ft cable that connects to the Interface Module along with the Magellan all-in-one sensor cable.
