Abstract
An electrostatic spray applicator system of the type utilizing pressurized air from an external source to develop the electrical voltage driving conditions within a spray applicator. The electrical operating conditions are represented by electrical signal generating devices within the applicator, and these electrical signals are converted into optical signals within the applicator for transmission to a remote source. The optical signals are received at the remote source and converted back into electrical signals corresponding to the parameters being measured, and are subsequently converted into decimal display values for visualization by an operator.
