PLM Air spring elements
PLM air spring elements offer low-frequency vibration and shock isolation for measuring stations, coordinate measuring machines, fans, air compressors, motor and generator units, high-speed presses and more.
The PLM air spring series comprises low-frequency vibration and shock isolators which reduce undesirable vibrations while simultaneously levelling the supported devices.
When used as a vibration damper, the internal air chamber already guarantees a signicifant isolating effect from 5Hz upwards. In an optimal loaded condition, the natural frequency is 3.0 Hz. PLM air spring elemets also isolate in a pressure-free state.
- Low natural frequency of 3 Hz,
- Easy level control via integrated valve,
- Height regulation control on request,
- Ratio of horizontal to vertical natural frequency 1:1.
Areas of application:
- Measuring tables,
- Test benches,
- High-speed presses,
- Production plants.
PAL Air Spring Elements with Automatic Level Controls
Air spring elemets of the PAL series offer superior low-frequency vibration isolation for measuring devices, electron microscopes, MRT equipment, coordinate measuring machines and precision manufacturing machines.
PAL air spring systems use level-controlled air springs. These isolators are ideal for conditions which require a constant level and vibration isolation at the same time.
Standard PAL isolators have a natural frequency of up to 1.7 Hz – depending on the height of the isolator. Even lower natural frequencies (up to 0.5 Hz) are possible for isolators manufactured according to customer specification.
A complete PAL system consists of at lease three master isolators for a 3-point level control. Each isolator has a built-in level control valve which functions as a load detector and height control.
PAL air springs react quickly to changes in load or balance, with deviations from a preset position being automatically readjusted.
- Low-frequency isolation, natural frequencies of up to 0.5 Hz possible.
Areas of application:
- Test and measuring equipment,
- Aircraft and automotive test benches,
- Foundation bearing surfaces.
