VL 255 PMMV

Vacuum leak detector with extended electronic functions (E) in a weatherproof housing (P) and digital manometer (M).

A sensor in the suction line detects any occuring liquids and triggers the alarm. Both the pressure controlled alarm and the alarm triggered by the liquid sensor result in a shutoff of the vacuum pump and in the closing of the solenoid valves in the suction and measuring line.
