MLDAQ-WT-50

The Backbone Of Your Automated Data Acquisition Solution

The Canary Systems® MLDAQ-WT-50 is a powerful, rugged and reliable wireless data acquisition Base Station. It provides a broad range of measurement and control functions and serves as a Base Station for wireless deployments, in particular from our WRMT-AT Wireless Remote. A single Base Station is capable of supporting up to 20 remotes with multiplexers, and as many as 336 remotes with single instruments. 

The MLDAQ-WT-50 supports measurements from a wide range of available sensors, including vibrating wire, load cells, micro-electro-mechanical (MEMs) sensors, flowmeters, linear potentiometers, thermocouples, thermistors, SDI-12 sensors, 4-20mA sensors, weather instruments such as wind sets, rain gages, temperature and humidity.

At the heart of the system is the CR6 Measurement and Control Module. This MCU features very flexible programming and communications, along with large internal data storage, and provides for reading all commercially available vibrating wire instrumentation including piezometers, strain gages, crack/displacement meters, in-place inclinometers and load cells. Canary Systems MiniMux or MultiMux multiplexers can also be installed to expand the number of measurement channels.

Communications options include TransNet 2.4GHz or 900MHz radios, suitable for long-range communications up to 30 miles.

Battery & Enclosure

The large 50AHr battery supports applications requiring high power consumption communication or measurement peripherals. The system is supplied with an AC powered battery charger as well as 40W solar panel.

The MLDAQ-WT-50 base station is designed from the outset for operation in demanding environments. Enclosure includes NEMA 4/12 rated painted steel. Mil-spec connectors and industrial cable glands additionally protect against harsh conditions and the elements.

Optional uni-strut mounting kits are available to provide for pipe mounting of the enclosures. The enclosures are easily wall-mounted using the integrated enclosure mounting tabs.

The MLDAQ-WT-50 comes with a 1-year limited warranty.
