New! First to market BACnet gas detection transmitters. BST series BACnet transmitters detect a wide range of gases accurately and reliably. The BST connects to a BACnet MSTP network, baud rate and MAC address are field adjustable. LED power and alarm indication. Optional digital display, watertight enclosure and on-board relay.

 

Features:

  • MS/TP BACnet communication
  • Adjustable baud rate
  • available 4-20 mA output signal
  • optional relay
  • optional LED display
  • thermal resetting fuse
  • LED indicator for power and alarm status
  • simple calibration proceedure

The standard housing is rugged PVC and an optional watertight polycarbonate housing is available to suit different applications.

Calibration and maintenance procedures are simple and are easily performed in the field.

Gases Detected:
CO, NO2, Ammonia, Chlorine, Ozone, Combustibles, Refrigerants, Oxygen, NO, SO2, Hydrogen and more.Applications:
Vehicle exhaust – parking garages, repair shops Arenas – Ammonia, CO, NO2 Pools – Chlorine, Ozone Food plants – Ammonia … and many more
