Leak testing using the differential pressure method
The operating principle is based on measuring the pressure change between a sealed test part and a sealed reference volume within a given measuring time. The core of the measuring system consists of a differential pressure transducer with automatic zero point correction.
Operating the leak tester
Programming of the control and test parameters is menu guided - no special knowledge is required. The test parameters are stored in the program register and can be recalled as required. Different selectable languages are available.
A write-protect key switch ensures data security. Data can be read but not modified by the operator.
Machine control systems are able to communicate with the leak tester via the standard parallel (discrete I/O) interface or
optional Profibus respectively Profinet.
The USB interface at the front of the leak tester offers an easy to use storage of test results or test programs.
