Its a device used in grinding process when AE contact is needed. These situations happens when machine design or high frequency , mechanical or electromagnetic noise does not allow the usage of other AE sensor types. It uses the coolant present in the grinding machine which can be water or oil. A separate supply from the cutting string is taken from the coolant filter and is pointed towards dresser. Within 1 millisecond the noise of touching grinding wheel with the dresser is given back to the coolant. It has a polyurethane pipe which can easily be fixed in grinding machine coolant supply.
