997

997 is a high-frequency, integral cable accelerometer. This high frequency accelerometer is used on machinery with gear mesh or small bearings, such as high-speed machine tool spindles and compressors. At high frequencies, there is little vibration in terms of displacement and velocity, however tremendous amounts of acceleration amplitudes may be present. It is not uncommon for vibration amplitudes on a very high speed gearbox to exceed 80g peak prior to failure. High frequency accelerometer with low voltage sensitivity will prevent sensor overload from these high amplitudes. The 10mV/g sensitivity is commonly used due to its high amplitude range which can prevent sensor overload. Whereas a 100mV/g accelerometer may overload at 50g peak, a 10mV/g sensor will measure to 500g peak.
