The NLT WIOD adds a layer of flexibility to the way your mine communicates and operates. The WIOD (Wireless I/O Device) is an industrial-strength, wireless micro-controller that constantly reads information from sensor devices like gas and air flow monitors, ventilation fans and pumps.  When unacceptable reading levels are found, the WIOD immediately reports the findings over the network and important measures such as turning on air fans or initiating an evacuation can automatically occur.

Mine operators are no longer limited by cables for asset tracking and data gathering.   In addition, all readings, alarms and messages can be displayed on the NLT Digital Mine™ Software or other OEM software solutions.

The WIOD can be used anywhere Wi-Fi is present, making it practical for both surface and underground mining:

  • Take gas and air flow readings in real time and action alarms, and pumps over the WiFi network. (Ventilation-on-Demand)
  • Eliminate costly fiber runs to large fixed equipment such as belt drives and power centers.
  • Permanent, temporary or portable solutions
  • Software-independent
  • Rugged mine-ready design, IP67 enclosure
  • Works with multiple brands of fixed gas monitors
  • Wi-Fi trackable device
