SPEKTRA, the company that specializes in the development, production and support of Shock & Vibration Calibration Systems, introduces the CS18P HF, the world’s only production Primary Vibration Calibration System for high frequency vibration calibrations. The CS18P HF Primary calibration system uses a laser vibrometer as the primary reference standard to accomplish absolute calibration of vibration transducers, calibrators and meters. The system achieves a frequency response range from 10 to 20,000 Hz for transducers with weights up to 200 grams, includes a resonant search capability to 50,000 Hz, and complies with ISO 16063-11. A high-frequency, air-bearing vibration exciter with vibration isolators is used to achieve the performance required and the low levels of uncertainty. The high performance standards achieved by this Primary calibration system are desirable for national metrological labs, calibration labs with outstanding quality demands, research and development facilities, and quality assurance departments at transducer manufacturers. SPEKTRA is a well-known supplier of Vibration Calibration Systems to customers worldwide. The company has developed a broad range of Calibration Systems, from very low frequency systems to high frequency systems, and both Primary systems and Secondary systems. These are fully automated systems that are ideal for facilities that process many calibrations each day as well as engineering and development testing.• frequency range 5 Hz ... 20 kHz • vibration exciter SE-09 • sensor mass up to 200 gram (DUT) • environmental conditions: temperature 23°C (± 2°C) and relative humidity 30 % ... 75 %
