Appts. for detecting discharges in chamber carrying flowing medium - has light conductors with one end in chamber, one opposite photoreceiver

摘要

The arrangement for detecting discharges in a chamber (2, 3) through which a medium flows contains at least one light conductor (11-13) with one end protruding into the chamber and the other end opposite a photoreceiver (16-18) which generates electrical signals corresp. to detected discharges. The photoreceivers are connected to an evaluation circuit (22). Several light conductors can be arranged is spatially separated positions, each with its second end opposite an associated photoreceiver. ADVANTAGE - More cost-effective and flexible.
