ABSTRACT:
A micromovement measuring device records creeping and dynamic infraprocesses both of natural and artificial origin, including seismic processes or infrasound and gravitational waves. The device has a sensitivity for measuring in a wide dynamic range. The device includes a measuring element, a sensitive element, a membrane, a signal conditioner, a fixing electromagnet, and a pulling electromagnet. The pulling electromagnet is located on the membrane which increases the range of the measurable movements. A hermetic housing prevents the formation of oxides or similar films at the working surfaces of the measuring and sensitive elements. A method of converting movement to electric signals is performed by the device, which takes an electronic field emission current to be a characteristic of quantization, and so movements in the range of Angstroms may be recorded.
