Abstract:
An instrument is described for measuring frequencies of 0 to 100 cps, and accelerations of vibrations up to 30 g gravity and also the description of an instrument for measuring static accelerations and tilts. The instrument consists of the following basic parts 1 theACCELERATION SENSING DEVICE 2 the adjusting device for fixing the sensing device on the object and 3 a measuring part in which the power supply system of the sensing device is concentrated. For recording the acceleration of vibrations in the instrument, the possibility of switching in the MPO-2 loop oscillograph and an electronic oscillograph is provided. The instrument is fed from a network of 127 or 220 volts ac. The entire weight of the instrument is 5 kg. The weight of the sensing device with adjusting device is 160 g gravity. Author
