I'm trying to attach a sensor to some tubes to measure the level of liquids in them.
One tube contains toluene and the other contains Recosol R55 (shellite).
But I am concerned about the safety of doing this. Could the capacitance sensor ignite these liquids? is this even possible?
Obviously I need to check with the suppliers of the device. However, most of datasheets for level sensors omit this information. Perhaps they are not game enough to make any claims about their sensor in this regard.
I don't really understand capacitance and whether it can ignite flammable liquids.
