Hydraulic, Pneumatic and Leak Testing

CAT design and manufacture a range of machines for detecting and measuring the internal and/or external leak rate in components as a means of gauging performance and quality testing.


We manufacture a range of machines for both hydraulic and pneumatic testing using either commercially supplied equipment – for example the appropriate flow meter or a combination of pressure chamber and transducer, where the leak is monitored and compared to limits and time to produce results. As appropriate, leaks may be recorded as either pressure rise or pressure decay depending on the characteristic being monitored.


Vision systems are another solution depending on the nature of the test where it is difficult or impractical to form seal around the leak interface.  When the leak is external and visible on the surface of the component, it may be defined by the change in the number of pixels surrounding the component in the monitored area


Leak detection specifications

   
test pressure from 70 mbar to 3000 bar 
temperature range ambient to 60°C depending on the type of test, but could be significantly higher
flow range measurable from 0.01 cc/min up to 20cc/sec and higher
cycle time from 10 seconds
evaluation criteria pressure change over time, timed pressure drop, measured flow, blob growth
measurement medium                  air, hydraulic oil, calibration fluid, water
