General Purpose
Supports a wide range of available sensors including Vibrating Wire, MEMs, SDI-12, and 4-20mA
General Purpose Datalogger
The Canary Systems® MLDAQ-W-50 is a powerful, rugged and reliable wireless data acquisition station for general purpose use.
The MLDAQ-W-50 supports measurements from a wide range of available sensors, including vibrating wire (with optional vibrating wire interface), 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 a CR6 MCU featuring very flexible programming and communications, along with large internal data storage and a Vibrating Wire Interface. It provides for reading all commercially available vibrating wire instrumentation including piezometers, strain gages, crack/displacement meters, in-place inclinometers and load cells. Expansion of the number of measurement channels available per station with a Canary Systems® MiniMux.
An optional HART interface can be installed to gather data from HART enabled industrial process measurement and control applications.
Battery & Enclosure
The large 50AHr battery supports applications requiring additional high power consumption communication or measurement peripherals. Systems are supplied with AC powered battery chargers as well as solar panels.
The MLDAQ-W-50 general purpose datalogger is designed from the outset for operation in demanding environments. This includes 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-W-50 comes with a 1-year limited warranty
