Your vibration test systems need to be calibrated, but they are:
- not portable
- permanently installed, or
- cannot be taken out of the production process for days on end?
SPEKTRA LABS has been the first and so far only calibration laboratory to offer on-site calibrations for vibration test systems at the DAkkS level since 2017. Our specially trained experts calibrate your entire vibration test system directly on-site, at your facility. Our laboratory is accredited according to ISO/IEC 17025 for the calibration of vibration test systems.
Your benefits
- Calibration of your vibration test equipment on-site by specially trained and experienced technicians
- Directly at your site to avoid long downtimes
- Possible deployment anywhere in the world
- Conclusions on the condition of all electrical and mechanical components of the test system
- DAkkS accredited calibration certificates
- Independent from manufacturers
- First and only DAkkS accredited mobile laboratory for on-site calibration of vibration test systems
The reference sensor can be calibrated in the SPEKTRA DAkkS accredited laboratory in preparation of the on-site calibration. The determined current sensor sensitivity is then used in the software of your vibration control system in order to obtain smallest possible deviations during the calibration of the system.
On site, the vibration test system is then used to provide vibration accelerations, which are measured using a calibration system that is traced back to DAkkS standards. (These accelerations are measured as a function of the frequency in the working area of the system.) For this purpose, the reference sensor is mounted on the coupling surface of the back-to-back standard, which is attached to the armature of the vibration exciter.
The calibration is performed by comparison, which is obtained by comparing the acceleration indicated by the vibration test system with the acceleration actually measured by the calibration system. In order to assure reliable results about the amplitude linearity of the provided acceleration, different acceleration amplitudes are provided at a fixed frequency, which are also measured with the calibration system.
A calibration of the entire measuring chain can also be carried out for the operation mode "shock". The vibration test system provides shock-shaped accelerations, which in turn are measured with the calibration system.
A calibration certificate acc. to DIN EN ISO / IEC 17025 can be issued about the deviations that are thus determined. SPEKTRA LABS is able to calibrate each vibration testing system independly from any manufacturer.
In addition to accredited calibrations, further measurements, such as the RMS value of a noise profile or measurements of the lateral acceleration, are also possible. This allows you to draw conclusions about the condition and the behavior of your vibration test systems in various stimulation - of all electrical components, as well as of mechanical components.
The frequency ranges, accelerations, control channels and sensors can be adjusted depending on the performance of the system or regarding your individual requirements. Similarly, slide tables for horizontal excitation can be included in the calibration.
