Techni Measure can now offer an extensive range of vibration and acoustic calibration systems, manufactured by SPEKTRA, based in Dresden, Germany. Systems are available from very low frequency long stroke shaker systems, through to high frequency shock systems for amplitudes up to 200,000g.
The CS18 MF calibration system is the general purpose range offering calibration frequencies from 3Hz to 10kHz. The CS18 VLF system is the low range long stroke shaker system that enables testing from 0.2Hz to 160Hz, and the CS18 HF system offers higher frequency testing from 5Hz to 20kHz. This modular range, based around the CS18 core, is available for either secondary “back-to-back” comparison calibration (systems are supplied with a reference standard accelerometer) or primary “absolute” calibration using a laser vibrometer. A battery operated hand held vibration shaker, model CV-01, is also available for testing sensors up to 150 grams. Several different systems for primary or secondary shock calibration are also supplied ranging from the CS18 LS for shocks up to 200g, through to the model CS18 VHS for measurements up to 200,000g. The CS18 SPL offers secondary sound pressure level calibration for ¼”, ½” or 1” microphones, and there is also a free field calibration system available. A wide range of vibration and shock exciters from SPEKTRA and APS are available for structural excitation and modal assessment. instance, to discuss the possibilities.
There are many options and extras for these systems and it is important for us to understand exactly what any application requires, so that we can offer a complete solution. In the first instance we would usually visit your premises to discuss the possibilities. We would be pleased to offer our advice on the specification and use of any of these calibration systems, please contact us
