Point Gas Detectors

BFT-44 Single/dual transmitter - NRTL/CSA approved

  • QVGA color Thin Film Transistor Display (TFTD) displays engineering units and monitored data as a 30 minute    trend bar graph.
  • The display changes color to indicate alarm status.
  • Ethernet: embedded webpage for configuration and HMI, Modbus® TCP master/slave.
  • Webpage offers offsite viewing capabilities.
  • Redundant Modbus® RTU, EC, LEL, 4 – 20 mA inputs.

The BFT-44 transmitter further builds upon the success of the earlier BFT-48 transmitter. This versatile unit has a vivid color display which changes color to match alarms states. The unit also has an embedded web page enabling an intuitive remote user interface. The web page is accessed through a standard Ethernet connection and allows the transmission of data over existing network infra-structure to our BFC-64 controller, smart phones, PC’s, and tablets.
