Abstract

The detection device comprises a pick-up of shocks provided with a transducer, e.g. of piezo-electric type, capable of converting shock waves produced by the particles into electrical signals, which can be manipulated in an electric treatment circuit. This is modified in such a way that the transducer is mechanically coupled to a vibration transmitter subjected to the bombardment of the particles and located wholly on the outside the pipe into which the transmitter penetrates. The electronic treatment circuit is one in which the shocks caused by the impact of the particles on the vibration transmitter are counted. The device enables the piezo-electric crystal to be adequately protected yet easily accessible, while the vibration transmitter can be designed to resist the bombardment of the particles entrained by the gas and can be specially treated to resist erosion. The device enables the solids content to be monitored to prevent damage to valves etc. in the pipeline.
