In September, an international workshop at SPEKTRA provided all participants an excellent opportunity to exchange ideas with other top specialists from industry and science to enhance their international co-operation.
With a specially developed device for the pneumatic shock exciter SE-201 PN-LMS, SPEKTRA is breaking new ground in shock pressure calibration. Now, dynamic tests are possible that are more consistent with reality than existing static solutions.
AFrench nationalinstituteis one of thefirst customers of the new vibration exciter and uses the SPEKTRASE-13for absolutecalibrationof heavyseismicsensorsusing the laser vibrometeras areference.SPEKTRAhas provided a completeCS18PVLFPrimary Calibration System, whichallows not onlythe verticalexcitation with theSE-13 but also the horizontalexcitationof the sensorson theAPS129 vibration exciter.
For calibration and analysis of accelerometers using a laser vibrometer the NIST recently acquired a SPEKTRA CS18 Primary Calibration System. The system is able to measure motions at molecular levels up to very high frequencies of 50 kHz.

New sensor technologies based on micro-mechanical structures (MEMS) increasingly require mechanical tests in the frequency range beyond 20 kHz. In this high frequency range, the trick is to stimulate the DUT with well-defined oscillations without causing uncontrolled vibration and transverse movements by resonance of the exciter. The new SE-11 vibration exciter provides the ability to excite the DUT with very low lateral accelerations to the main axis of motion in the frequency range of 1 kHz - 50 kHz.
In February 2014 SPEKTRA has been successfully accredited to calibrate artificial mastoids. Those mastoids are usually used in the field of audiometry. Consequently, SPEKTRA is the first calibration laboratory to recieve this accreditation in Germany and can now offer this sort of calibration.
"Consistent customer orientation and optimized processes in conjunction with the high quality of our services have always been part of the self conception of SPEKTRA, "explains CEO Dr. Holger Nicklich." For 2013, we had therefore set ourselves the goal to disclose our measures for quality management."
