Extractive Measurement (Bypass) Cell

WHAT IT DOES

  • The Extractive Measurement Cell is a measurement head for our series of GasFinder analyzers that provides a path average concentration within the process (active measurement path)
  • The Extractive Measurement Cell is built as such so the process does not come into contact with the optical components of the measurement head.
  • The process can flow unobstructed through the cell without significantly altering pressure or flow characteristics
  • The length of the active measurement path can be altered by changing the length of the 1” NPT pipe.

HOW IT WORKS

  • The analyzer can be mounted locally or remotely
  • Fibre optic cable carries the laser light from the analyzer to the remotely mounted transceiver in the Extractive Measurement Cell
  • The active measurement path is formed by the laser passing through the window fixtures (and the process) and is returned by the retroreflector mounted in the opposing cover
  • The laser light is then collected on the photodiode and the signal is carried back to the analyzer via coaxial cable
  • The ppm-m concentration is then transferred from the analyzer to the PLC or DCS
