JJG 676-2019 《Vibration Meters》 Related products

Standard JJG 676-2019 specifies the requirements for the first verification, subsequent verification and inspection in use of a vibrometer for the measurement of vibration in the 0.1 Hz to 10 kHz Frequency range. A vibrometer is a device used for the measurement of vibration signals. Acceleration, Speed, Displacement and Frequency of vibration are finally obtained by sensing and converting vibration signals through vibration sensors. Vibrometers usually consist of vibration Sensors, preamplifiers, bandpass filters, calculus circuits and data display analysis or recording devices. This standard describes in detail the technical requirements of vibrometers and performance methods of verification to ensure the accuracy and Reliability of their measurement results. Before use, please refer to JJG134, JJG233, JJG298, JJF1156 and relevant documents such as GB/T 20485.11-2006 and GB/T 20485.21-2007 to ensure that the vibration meter meets the technical and Measurement requirements of the standard.
