dust detection
(OP)
i need to detect when dust is present in an exhaust stack and was wondering if anyone knows of any probes or sensors that could be used. I have heard of using triboelectric sensors but these are exspensive and seem to be abit ott for what i want. I have tried using a differnetial pressure switch to monitor any change in pressure between clean and dirty side of the filter when we get a ripped filter bag but there wasnt any significant change in pressure so therefore it didnt work, but i am willing to listen to any suggestions.

Also, dust reduces optical transmission, so measuring changes in optical transmission might work as well.

A light is flashed and if more than X amount of back-scatter is detected by a sensor next to the lamp, then there is fog = run horn.
You can use this same method in a stack. You set up the light, and a receiver next to it, and then run a permanent purge air into the barrel of the instrument to prevent any contamination of the sensors.
Someone must make this.
