The PCME STACK 602 is a cross-stack optical system used extensively for compliance measurement in the Power, Steel and Cement industries. With TUV approval for EN 14181 and EN 13284-2, the instrument is primarily used in applications with electrostatic precipitator boilers, calciners and large diameter emission stacks. The PCME STACK 602 can be used in processes where either direct Opacity (and extinction) measurement is required, or dust concentration measurement for specific applications via calibration against the Standard Reference Method.

Traditional Opacity instruments measure the intensity of received light; ENVEA UK's patented DynamicOpacity Ratiometric Opacity technology instead measures the temporal variation (rate of change) in light, or Optical Scintillation. This offers a significant advantage over traditional Opacity methods, as the ratiometric measurement is unaffected by lens contamination allowing the instrument to operate with lens contamination exceeding 90%, therefore greatly reducing costly process intervention for lens maintenance and servicing.

  • Automatic Zero and Span checks to monitor for instrument integrity
  • Extended maintenance intervals due to reduced sensitivity to lens contamination
  • Sensor lenses are accessed in-situ for lens cleaning, ensuring correct alignment of transmitter and receiver even after maintenance
  • Entry and Standard control unit with advanced graphic and user interface screens, features including alarming, graphical trending, data logging, 4-20mA output.
  • PLUS control unit option for sensor networking (up to 16 sensor channels) via industry standard Modbus, multiple inputs for external devices (e.g. for Temp and O2 normalisation)

The PCME STACK 602 supersedes the SC600T, a similar DynamicOpacity™ Ratiometric Opacity instrument.
