SPEKTRA would like to invite you to visit us on the exhibition AutomotiveTestingExpo in Stuttgart, Germany (16th June – 18th June). We will present two new developments besides our worldwide established calibration systems for vibration and acoustic calibration: the vibration control system VCS401 and the shock exciter HOP-MS for shock amplitudes up to 4,000gn.
After the successful graduating at the Dresden Technical University with a Dipl.-Ing. degree in engineering with specialization in applied mechanics Martin Iwanczik will join the SPEKTRA Team henceforth. The calibration exciter has been developed together with other colleagues for a dynamic calibration of accelerometers and force sensors to extend the efficiency by calibration services and CS 18 calibration systems. The Diploma thesis titled “Development of a resonator to calibrate accelerometers” would have been completed with excellent result.
SPEKTRA participates in the NCSL International Workshop & Symposium in Nashville, TN, USA on 6-9 August 2006 with a booth displaying accelerometer vibration calibration systems.
In addition to factual information, our focus has been on fast and efficient navigation. For this reason we have completely
revised the layout and user interface and added a site presenting the latest topical news. Please do not hesitate to send us
your suggestions for further improvements.
The latest software version of the
CS18 FF system is based on the experiences from preparing our first accreditation
for acoustical quantities and accreditation extension to include sound level
meters. This software version is available as from now.
In addition to the rooms of the accredited calibration laboratory that have been air-conditioned from the very beginning, all other workrooms have now been furnished with air-conditioning, too, so as cope with the growing demands for quality assurance in the departments of incoming goods, manufacture and environmental simulation. Thus our experts in the development and sales departments and the office can keep cool also in extended summer periods with high temperatures outside.
When calibrating acceleration sensors, particular attention must be paid to the vibration exciter as an important component part of the calibration system. The quality of the SPEKTRA CS18 HF high frequency calibration systems could be further increased only by developing a suitable vibration exciter SE-09. The result by far outperforms all solutions that have been available so far.
The high-shock exciter can be used as a single component HOP or as a part of a complete CS18P HOP Primary or CS18 HOP Secondary Calibration System to calibrate shock sensors. Excellent reproducibility, automatic control and wide range of application up to 100.000 gN mark out this exciter.

The software package VCS201 for
sine, noise and shock has been reworked and further developed. Performance and reliability
have been improved and new options have been introduced. The update is free of charge for former customers.
After graduating at the Dresden Technical University with a Dipl.-Ing. degree in acoustics Andreas Kunadt has joined the SPEKTRA team. Being an acoustics engineer, he will further be the responsible expert for the extension of acoustical calibration services as well as the CS18 FF/SPL calibration system and engineering services for acoustical test systems. The Diploma thesis titled "Calibration of intensity and sound velocity probes in an acoustic free-field" will expand SPEKTRA calibration capabilities in the near future.
The compressed air supply system was renovated and expanded with the aim of meeting the demands of environmental tests and calibration runs using ThermoStream or ThermoJet. As a result, a central compressor can supply air at a rate of up to 10 litre per second to a ThermoStream or ThermoJet unit. Investigations into the temperature response of test objects are thus made possible in the range between -75°C and 225°C and with temperature gradients of up to 18 Kelvin/second. Compressed air that has been dried and cleaned is available for calibration tasks.
Using our new product HOPkinson bar, shock sensors can be calibrated by CS18 HOP with a full shock period at up to 500.000 m/s2. Prestressed force sensors can be calibrated dynamically with sinusoidal force excitation. Pulse hammers can be calibrated with respect to their pulse force.
A new set of services has been compiled especially for the calibration of Human vibration meters. As a result, the new requirements of standard DIN EN ISO 8041 are met, too.
Thus as from now, customers can submit
their sound level meters to SPEKTRA
for DKD calibration. Moreover they can combine DKD calibration with a thorough
check of their electrical characteristics in the framework of a periodic test according to DIN EN 61672-3 resulting in a
declaration of conformity. The results will be certified by issuing
a DKD calibration certificate that,
if so requested, can be extended to include a declaration of conformity with the manufacturer's specification. In the field of acceleration, some modifications and extensions have been made. Charge amplifiers may now be calibrated
up to 50 kHz with a DKD certificate. For further information, please refer
to Annex 5 of our accreditation certificate that you will find under Certification.
SPEKTRA took part in the Sensor +
Test trade fair in Nuremberg another time. Our high expectations in this trade
fair were met in full. It turned out that the interest of
our customers at home and abroad in our CS18 calibration system has again risen
compared with recent years. Apart from the type VCS 201
Vibration control system based on SPEKTRA hardware, first prototypes of the
types VCS 301 and VCS 401 Vibration control systems based on National
Instruments hardware were presented.
The hardware of this scaleable
family of controllers is based on powerful and future-oriented components by SPEKTRA
and National Instruments. Interfaces to common tools on the market such as
LabVIEW, LabWindows, LabWindowsCVI, ... provide for flexibility for the user.
SPEKTRA participates in the Measurement Science Conference in Anaheim, CA, USA on 1-3 March 2006 with a booth displaying accelerometer shock and vibration calibration systems.
