Numerous vibration tests are carried out in a temperature range far above or below room temperature, where the sensors are usually calibrated.
SPEKTRA has developed a calibration method which, in addition to the temperature range from -55°C to 120°C, can also cover the wide frequency range from 10 Hz to 10 kHz.
The smart SPEKTRA S-TEST solutions allow highly efficient characterization of your devices - from development phase up to industrial large-scale production.
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.
In September SPEKTRA GmbH Dresden organizes again our annual seminars for newcomers and experienced staff of calibration laboratories in the fields of vibration and acoustics.
For several yearsSPEKTRA has been involved in the project"genialsozial"that enable youngpeople in poorerregions of the world to get new perspectivesand enhance theireducational opportunities.
Sensors with digital output instead of analog signal output have found their way into many products in the consumer goods sector and industry.
Increasingly, these sensors are also used in laboratories and in precision measurement systems, which is why they need to be calibrated in accredited calibration laboratories.
Do you need lowest voltages with high-precision at your calibration benches or for quality assurance that can not be provided by your conventional measurement systems?
Measurement microphones have so far only been calibrated with a one- or two-point calibration using a calibrator but can now be examined over the entire frequency range using the SPEKTRA SQ-4.1/4.2.
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.
SPEKTRA Schwingungstechnik und Akustik GmbHDresden presents its new website in 2015.In addition to improving the corporate design,the structurehas been completely redesignedandnow shows productgroups and applicationsclearly arranged.Thevisitor can see new products, activities andupcoming events at first glance.
In early December,representatives of nationalmetrology institutes will meet atSPEKTRAinDresdento discusscurrent and futurechallenges in thefield of vibrationmeasurement technology.
In a few weeks time the world's leading trade show for electronic components, systems and application will start.
SPEKTRA will present at its booth individual solutions for the characteriziation of MEMS sensors and MEMS final testing / adjustment systems as well as new products, like the new calibrator CV-01.
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."
