Negli impianti di rivelazione di scintilla, in genere sono necessari oltre ai rivelatori specifici, anche altre apparecchiature.

SKU: EV-521 Categories: ,


In spark detection systems, devices other than the specific detector are normally required. Usually these additional devices allow the detected sparks extinguishing, the acoustic signalling of alarms, the control of extinguishing systems and the eventual block of the silo material feeding system.
The operations described above are carried on by the EV521 Control Unit in very short times, with precision, in the right sequence and so definitely in the best way.
The EV521 Control Unit has been designed to be used together with our EV395 and SCL01 Spark Detectors. It can control up to two EV395-SCL01 detectors. This unit automatizes all the operations and so allows to use the Spark Detectors in a simple and reliable way. Moreover the EV521 Control Unit avoids the necessity to buy a lot of devices coming from different manifacturers and so the problem of coupling this eterogenous devices. The EV521 installation is very simple and can be carried out in a short time.
