Hi friends,
I have a customer that is looking for some advice on upgrading the level system in their coal hopper. It is at a coal bagging plant and this hopper feeds the bagging line. They run everything from rice to stove coal through here. When they coal is dry, it isn’t very dusty, so when the coal is wet, it is a damp environment. They are currently using bindicators but aren’t very pleased with their accuracy. Esp. When running larger coal, their are large enough voids betwee the pieces of coal that the sensor thinks the level has gone down. Because of the dust and dirt, I shy away from any sort of prox or photo eye. Because of how the coal will pile, I don’t think a radar or sonar would be a good idea either. I suggested a load cell, but they would like not to have to use them if possible because it would take a lot of modifications to their existing setup.
Any advice on what sensor you would recommend form this set up? They currently have two sensors......one for on and one for off. They would like one sensor and we would use a small plc to do control the start/stop. Also then our high and low levels would be much more configurable.
