Pulsed air pressure with temperature variation:
This test bench produces the specified pressures and temperatures inside the parts, whilst maintaining a different temperature outside the parts.
The test can also be combined with oscillation, e.g. for pipes (linear to-and-fro movement at a frequency of approximately 1 Hz).
Pressure: up to 3 bar relative - internal T°: up to 200°C.
Pressure cycling: this test bench can produce cycles of positive pressure pulses followed by negative pressure pulses, coupled with hot/cold climatic cycles.
Pressure: -900 mbar to +5 bar relative
External air T°: -40 to +150 °C
- Air-tightness: the quality of the sealing can be checked either by an air in air measurement (ATEQ instrument), or by bubble detection (air in water).
Pressure: up to 10 bar
