Leak Tester 65eco

HeMaTech is known for rugged, durable leak testers featuring high accuracy. All over the world users trust in the reliability and service of HeMaTech Prüftechnik. In many industries leak testers using the differential pressure method are vital for continuous inspection in series production.

 

The 65eco is your compakt partner when looking for a reliable, cost-effective leak tester. It provides a good accuracy and is suitable for many applications. Where demands are higher or special applications need to be covered the Leak tester 60pro is available.

 

 

Benefits of the 65eco

HeMaTech leak testers provide many benefits:

 

  • automatic control cycle,
  • storage of test programs,
  • contamination free test,
  • reproducible measuring results,
  • short cycle times with high accuracy,
  • unambiguous results,
  • measured value display,
  • programmable test pressures and test times to suit
    testing to the production of many different components,
  • user friendly operation with interactive user guidance,

 

 

 

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.

 

Pneumatic System

  • Fast, accurate differential pressure transducer,
  • microprocessor controlled electronic pressure regulator
    for filling and test pressure,
  • pneumatic controlled shut-off valve to eliminate temperature
    influence,
  • optional leak simulation with precision needle valve for the
    connection of an external leak calibrator or test leak.

 

Electrical System

  • modular design microprocessor system,
  • battery buffered RAM for data protection,
  • alphanumeric keypad,
  • 5 inch color display,
  • write-protect key switch to prevent unauthorized program
    changes,
  • error messages as plain text,
  • menu guided programming and adjustment of parameters.
