Abstract
A spray malfunction detector system for electrostatic spraying apparatus having a sprayhead connectable to a high voltage source and for directing spray of charged particles of fluid towards an earthed target. The system comprises an earth circuit from the earthed target, a by-pass electrode located in the vicinity of the sprayhead and maintained in use at such a potential as to attract corona discharge from the sprayhead, and a current detector located in the earth circuit between the earthed target and any junction in the earth circuit and by which corona discharge joins the earth circuit from the by-pass electrode.
