FOR DEMANDING ENVIRONMENTS AND REMOTE LOCATIONS
The Canary Systems WRMT-A-12S is a Wireless Remote Station designed to monitor vibrating wire and level detection sensors. The Remote Station does not contain a data logger; instead, multiple remotes can be paired with a Canary Systems MLDAQ base station serving as the master datalogger. The WRMT-A-12S contains a Campbell Scientific AVW206 or AVW216 instrument with a built-in 900 MHz (AVW206) or 2.4 GHz (AVW216) spread spectrum radio, and a Canary Systems MicroMux or MiniMux multiplexer.
The AVW2xx is a vibrating-wire interface that allows to measure vibrating-wire strain gauges, pressure transducers, piezometers, tiltmeters, crackmeters, and load cells. In addition to vibrating wire sensors, the Remote Station also has the ability to read thermistor or resistive sensors. This allows the use of other types of sensors besides vibrating wire. The AVW2xx provides 2 sensor inputs. The optional MicroMux provides 4 Channels of VW sensor inputs, the MiniMux provides 16, expanding the channel measurement capability from 2 sensors to 5 or 17, respectively.
The built-in spread spectrum radio is available in 900MHz (AVW206) or 2.4GHz (AVW216) bands, depending on the application and desired range, and comes with the appropriate 900MHz 9dBi Yagi or 2.4GHz 12 dBi Yagi Antenna. Ranges of up to 20 miles (32 km) are possible.
Power to all components is supplied by a 12V 12AHr rechargeable lead-acid battery including a 20W solar panel. The battery is suitable for several weeks of operation without sunlight, and are delivered installed and ready to use. It should last for 3-5 years. The application and measurement interval have a large effect on battery life.
The WRMT-A12S is capable of retrieval and storage of its own battery voltages. These metrics are valuable to monitoring the status of power to the stations.
At the bottom of the steel enclosure are connections for the solar panel, external antenna and 2 or 4 cable glands for vibrating wire sensors. The charging is controlled by a Sunsaver charge controller unit.
The complete list of features and specifications is detailed on the AVW206/AVW216 and MicroMux/MiniMux data sheets available from our website or by contacting Canary Systems directly.
Warranty for the WRMT-A-12S is applicable for 1 year.
