Network Hubs

Network Hubs


  • Up to 30 devices per hub
  • Faster data control / transfer
  • No special tools required
  • Cabling simplified
  •  IP 66 Certified
  • System is configured as a large area network(LAN’) thus preventing data loss
  • This Network is in turn split into sub-networks (hubs)


Network Hubs


  • The GasDetek Sentinel Hub is incorporated into LAN’s
  •  The Hub allows effective control of individual areas within a large system
  • The Hubs break up a large network into smaller networks
  •  The Hub becomes the backbone of the system off which all the devices are run
  • Hubs would be used in any size system where there are more than one area with more than 15-30 sensors (The recommended maximum sensors per Hub is 30)


The Hub is a data transfer system with each hub controlling up to 30 individual devices (such as sensors) within the large network. This further enhances the system and also serves to isolate cut / damaged sensor data cables exclusively to within an isolated area
