Device for automatic verification of switching points of installed density monitors

The (EU) F-gas regulation stipulates regular verifi cation of density monitors installed in switchgear. In combination with a DILO lock valve it is possible to quickly check whether the density monitor switching points are triggered in time without disassembling the density monitor. Thus, the DensiControl IN allows very quick, easy and precise verification of the switching points without SF₆ emission.
The density controller to be verified is selected in the database and is separated from the gas compartment with the lock valve. After starting the measurement the gas in the density monitor is slowly released and collected in the internal storage vessel. During that procedure, the switching points are activated and recorded automatically. Furthermore, the switching points can be stored in the system with serial number and switchgear temperature and downloaded for documentation later on. After the measurement, the collected gas is pumped back into the switchgear.
