5. electronics built into one IP65 enclosure which has been specifically designed for easy installation and operation 1 3 How does it work The Snifter A2 uses Sintrols proven and reliable inductive electrification technology where the interaction of particles with the sensor rod causes a small electrical charge to pass between the particulate and sensor It is this small electric charge that provides the signal monitored by the electronics the signal generated is proportional to the dust level even if particles accumulate on the sensor Experience has shown that this method of monitoring dust level in gasses offers accurate results with minimum maintenance 2 INSTALLATION 2 1 Selecting the installation location The best location for installation is in a section of duct where the particulate has an even distribution and the flow is as laminar as possible This is to ensure that the sensor rod comes into contact with a representative flow of particles The ideal position would be in a section of duct that has no bends valves dampers or other obstructions for a distance equal to at least three duct diameters downstream or upstream preferable 5 x duct diameter Description of installation is presented in Figure 1 Recommended distance to duct bends D Duct diameter Snifter A2 User Manual PA SINIESL 3x D ox D Figure 1 Recommended distance to duct bends D Duct diameter In some applications a
