WHAT IT DOES
- The probe is an engineered solution for our series of GasFinder analyzers to remotely monitor the path average concentration inside of a stack or duct
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 stack/duct probe (transceiver)
- The active measurement path is formed by the laser passing through the stack/duct and being returned by the retroreflector on the opposing flange.
- The laser light is then collected 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
- In some cases, condensation and accumulated dust can cause optical interference or a blocked path.
- For cases of positive pressure, instrument air can be tubed in to the spacer flange to provide a flow rate of 1-5 l/min to keep the dust from settling
- In instances of negative pressure, the ¼” NPT port in the spacer flange can be left open to allow air circulation
- Install the transceiver and leave the retro flange off
- Remove cover plate on the transceiver
- Connect the visible laser from the troubleshooting and diagnostic kit (most stacks and ducts have a particulate load and the beam should easily be seen)
- Adjust the alignment screws so the visible laser beam is aimed through the opposing flange port
- Install the retro flange, remove the visible laser, and replace the cover plate on the transceiver
- It is important that the flanges are welded orthogonally to the duct and that the two flanges are mounted at the same height
- For high concentration applications
- For stack temperatures over 120ºC (250ºF), it is recommended to install a spacer flange
