Functional tests

Seize our broad experience with testing the most diverse properties of your products.

LIWO offers complex functional tests due to our experience with electrical, mechanical, magnetic, hydraulic or pneumatic series parts. In the process, different tests can also be combined each imbedded in proven systems concepts.

 

It is important during functional tests to subject test pieces to different input values within the demanded tolerances in a stable and supported way. In doing so the output values are checked to verify they are within the determined limits. Results are measurement points and characteristic curves and finally a good/bad statement.


 

 

LIWO software stores data and characteristic curves with test and time stamp in databases with the corresponding test piece and analyzes them statistically.

 

Our developer team with specialists from physics, mechanical engineering, electronics and software also solve extraordinary tasks. Put us to the test.

 

Typical input values:
Controlled pressures of different gases and liquids
Electrical currents and voltages also with diverse signal forms such as
Ramps or pulse width modulations
Rotation speed
Force / displacement
Vacuum
Flow rate
Temperature
Flame
Typical dimensions:
Flows, from the smallest leak rate at 1x10-8 mbar*L/s up to the largest flows of several cubic meters per minute
Pressures or pressure cycles of 1x10-9 mbar up to over 1000 bar
Electric currents
Voltages
Resistances
Force / displacement
Torque
Temperature
Camera photos
More characteristics can be determined from a combination of measurement values and characteristic curves such as:
Switch times
Hysteresis
Switch separation
Gradients
Gradient changes
Resistance stability
Maintaining envelopes
Determination of forces and paths from electrical measurement values
