General Purpose
Supports a wide range of available sensors including Vibrating Wire, MEMs, SDI-12, and 4-20mA
General Purpose Data Acquisition
The Canary Systems® MLDAQ is a powerful, rugged and reliable wireless data acquisition station for general purpose use.
The MLDAQ 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 are available as options to expand the number of measurement channels per station.
Battery & Enclosure
The 50AHr battery version (MLDAQ-50A/50S) supports applications requiring additional high power consumption communication or measurement peripherals. The system is supplied with AC powered battery chargers as well as solar panels.
The MLDAQ base station is designed from the outset for operation in demanding environments using a NEMA 4/12 rated painted steel enclosure. 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-50 comes with a 1-year limited warranty
