CTC’s family of low frequency, 1,000 mV/g accelerometers is specifically designed for low speed applications such as low speed rotors, main bearings, and gear box inputs. These shear mode accelerometers feature a larger seismic mass than standard size, 100 mV/g accelerometers. This larger mass imparts a greater force on the piezo ceramic, translating to better signal to noise ratio at low frequency vibrations.
