Dispenser malfunction detector |
(57) A dispenser for fluid under pressure has a sensor affixed to it to sense the pressure
of the fluid proximate the dispenser discharge opening to generate a pressure reflective
signal. A comparator is connected to receive the pressure reflective signal to compare
the pressure signal with a preselected band of pressure values which are selected
to reflect operating pressures when the dispenser discharge opening is opened. The
comparator generates a malfunction signal when the sensed pressure signal is outside
the preselected band.
