Verification device for verification of sealability of e.g. pneumatic fluid system, has time measuring device defining two time points and controlling pressure measuring device in direct manner regarding determination of pressure

摘要

The device has stop valves (3) i.e. 2/2 solenoid valves, and a pressure measuring device i.e. slider (6) that are provided between a pressure source (2) and a fluid system (1). The pressure measuring device determines pressure at two measuring time points to conclude leakage and unsealability based on detected pressure values. A time measuring device (7) defines the time points. The time measuring device and the pressure measuring device form a measuring unit (4). The time measuring device controls the pressure measuring device in a direct manner regarding the determination of the pressure. An independent claim is also included for a method for determining sealability of a fluid system.
