Image Flame Detector (OPTIS)

Features

Captures and processes the burner flame image through the CCD camera, and identifies the flame On/Off by its brightness and shapes. Using the CCD camera, it extracts and processes only the flame image data captured from a wide area, which can provide a very reliable detection and data from flame monitoring.

Flame Detector for Gas Turbines

Overview

This product inherits an IR-S type Infrared Flame Detector technology, which has been employed in many boilers at thermal power plants. 　Reliable photo diode is used for the sensor. By filtering incident light from furnace heat, it becomes possible for the detector to be unaffected by heat and focus on only near ultraviolet.

General-purpose Ultra Violet Flame Detector (YOKA-FD)

Overview

This product inherits an IR-S type Infrared Flame Detector technology, which has been employed in many boilers at thermal power plants. In addition to the explosion proof sensor, we also offer a light weight/compact size non-explosion proof sensor, which can be used depending on the location of your equipment. Our compact size sensor can be installed easily on DIN rail.

Features

  • Stable detection of flames, which are generated from various fuels (Gas & oils).
    Wave detection Range matches to the near ultra violet light wavelength generated by either gas or oil.
  • Detection of Low NOx Flames
    With the wider detection wavelength, it achieved the lower affect from the atmosphere detection which occurs at the time of low NOx combustion.
  • Long Operation Lifetime
    We have achieved the longer lifetime by adopting a semiconductor for sensor and high reliable parts for other sensor amplifier circuit.

    Flame Supervisor(MIRNDA-FD)

    Overview

    MIRNDA-FD is an industrial furnace flame supervisor which complies with Japanese Industrial Standard, JIS B 8415-2008 (revised in Nov. 2008).
    This product has a fuel valve shutdown function for safety control, in addition to flame detecting function.

    Features

    • MIRNDA-FD is an industrial furnace flame detector that complies with the safety regulation JIS B 8415:2008.
      1. Consists of a flame detector and a safety control system (Fuel shutdown valve operation).
      2. Safety start-check sequence, which confirms flame existence before furnace ignition.
      3. Self-cheak function (normal action check can be done more than once per day)
      4. Semiconductor element sensor. The long operation lifetime by adopting high quality components besides the sensor itself.
      5. Self-cheak function is processed through the electric circuit. No shutter maintenance for mechanical parts is required.
    • Various type of flame (by gas or oil) can be detected.

      Detection wavelength bandwidth is conformed to the emission wavelength near ultra violet bandwidth, which is generated by either gas or oil. Therefore, this sensor can detect both types of flame, and is applicable for many types of fuel.

    • Detection of Low NOx Flames

      With the wider detection wavelength, it achieved the lower affect from the atmosphere detection which occurs at the time of low NOx combustion.
