MLDAQ-WC

The Backbone Of Your Automated Data Acquisition Solution

The Canary Systems® MLDAQ-WC 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-A 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-WC 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 are available as options to expand the number of measurement channels per station.

The MLDAQ-WC comes standard with an RF4xxSpread-Spectrum radio for medium to long range telemetry. Numerous other communications options are also available, including 2.4GHz/5GHz WiFi, cellular modems, satellite, multi-drop interfaces and short-haul modems. Contact Canary Systems for assistance with your particular application to establish your communications requirements.

Battery & Enclosure

Two different power configurations are provided depending on power consumption and available recharging. The 12AHr battery version (MLDAQ-WC-12A/12S) is designed for applications with minimal power consumption, a larger 50AHr battery version (MLDAQ-WC-50A/50S) supports applications requiring additional high power consumption communication or measurement peripherals. Both systems are supplied with AC powered battery chargers as well as solar panels.

The MLDAQ-WC base station is designed from the outset for operation in demanding environments. Enclosure options include NEMA 4X rated fiberglass reinforced polyester (FRP) for the 12A/12S models and NEMA 4/12 rated painted steel for the larger 50A/50S models. 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-WC comes with a 1-year limited warranty.
