SPEKTRA on the exhibition Sensor + Test
Meet SPEKTRA in Hall 12, Stand 439

Like in all the years before SPEKTRA will have a booth on the exhibition Sensor + Test in Nürnberg, Germany (18.05. – 20.05.). Besides our worldwide established calibration systems for vibration and acoustic calibration, the vibration control system VCS401 and the shock exciter HOP-MS will be the main highlights on the stand.

High-g-Vibration-Exciters
New High-g-Vibration-Exciters fill the Gap between Standard Calibration Shakers and Shock Exciters

Common vibration exciters for calibration and sensor characterization available on the market are capable to provide acceleration amplitudes up to 100 g_n (1,000 m/s²) only. To apply higher amplitudes in a “metrological quality” shock exciters are commonly used. But the transient shocks have a rather broad spectrum that can contain spectral components close to the resonance frequency of the device under test (DUT). Thus calibration or measurement results can depend strongly on the properties of the shock exciter. In the worst case the DUT may even be destroyed by the shock. But how do you check amplitude linearity of a DUT that is not designed for higher frequencies? And if the result of a shock calibration depends on the properties of the transient shock signal, wouldn’t it be better to calibrate even sensors designed for shock measurements on a vibration exciter? There seems to be a gap between conventional vibration exciters and shock exciters in the amplitude range above 100 gn (1.000 m/s2) inhibiting such measurements. This article introduces two new vibration exciters that can fill this gap and shows the results of amplitude linearity checks of an acceleration sensor up to 500 g_n (5,000 m/s²).

SPEKTRA expands engineering service business
Range of applications could be significantly expanded

Since the establishment of SPEKTRA fifteen years ago engineering services were always one of our strongest business segments. Within the last years the range of applications could be significantly expanded. Especially investigations and design services regarding the appropriate integration of accelerometers into newly designed customer devices becomes a growing business.
