EV 521 - Control and Indicating Equipment for Spark Detectors

In the spark detector systems it is needed the spark detectors but also other electrical equipments.

In general these additional equipments provide for extinguishing of the detected sparks, for acoustic signalling and for the eventual block of the material transport system inside the silo.

The indicated operations are made with good precision, with the right sequence and so in the better mode, from the control and indicating equipment EV521.
