Assessment of serviceability

Vibration monitoring of sensitive devices to protect against operational failures

Environmental vibrations, both natural and induced, can have a negative impact on vibration-sensitive equipment and facilities such as laboratory equipment, semiconductor manufacturing equipment or data centres, and thus on the quality and reliability of their operation.

Continuous vibration monitoring with alarm function and remote data interrogation offers reliable protection against operational failures.

Vibration Criteria for the evaluation of vibration-sensitive devices and equipment

The VC curves (Vibration Criteria) define the limit values for the effective values (RMS) of the vibration velocity per one-third octave band, i.e. indicators for the average power of the vibration velocity per frequency band. In order to record the most sensitive VC curve (VC-G) with 0.78 µm/s RMS, a correspondingly low-noise measuring system is required.

MENHIR fulfils these high requirements, as the inherent noise is more than 10 dB below the VC-G curve. The one-third octave band calculation in the MENHIR is carried out in real time strictly in accordance with DIN EN 61260-1 Class 1 and thus enables comparability with other measurements and systems.

MENHIR is the ideal vibration measurement system for assessing the environmental vibrations that affect sensitive instruments.

Good to know

According to DIN EN ISO 9241-11, usability refers to the extent to which a system, product or service can be used by specific users in a specific context of use in order to achieve specific goals effectively, efficiently and satisfactorily.

Vibration Criteria
Vibration Criteria (VC curves) are used and accepted worldwide as the basis for evaluating equipment for vibration-sensitive instruments and tools and for designing structures to support vibration-sensitive equipment and processes. They were developed by Colin Gordon and co-workers.
