  • HD Flame Detector
    First industrial Flame Detector with an easy to use interface on a mobile app. The HD Flame Detector was designed for the Power Generation market and provides the highest level of flame discrimination in multi-burner applications ....

  • Product Overview

    The Forney High Definition (HD) Flame Detector integrates both Infrared (IR) and Ultraviolet (UV) optical sensors along with an amplifier and high speed signal processor. The high speed signal processor is able to analyze frequency resolution
    allowing for precise discrimination between multiple burners and background radiation. Two flame relays are available which can be triggered by either optical sensor. Four different profiles are selectable for maximum flexibility under different operating conditions. 4 to 20mA analog outputs are provided for remote display options.

    An industry first mobile app is available in two configurations from the Apple Store and Google Play. The Forney HD Detector app will allow the user to select a specific detector via Bluetooth. The user can then monitor the detector on their mobile device. A live Fast Fourier Transform (FFT) is also displayed. To tune the detector, the password protected, Forney HD Detector Pro app will allow the user to specify pick up and drop outs for flame on and flame off within the user specified frequency range or power spectrum density. They can also specify which sensor will be used for each flame relay and profile. Any fault codes are clearly shown with Reset capability. A PC based RS485 connection capability is also available.

    A single, flexible 12 wire custom cable is available in multiple lengths to make field connects simple. In many cases the existing field cabling can be reused. (Existing cables for Forney D85, UniFlame, and UniFlame II Detectors can be reused with transition adapters.)
