Seismometers and geophones |
|
Geophones are used as primary transducers of seismic and vibration measuring systems and complexes and can also be used in various fields of science and technology to measure (record) low-level vibration.
|
Seismometers that measure vibration speed on the basis of molecular-electronic technology.

Piezoelectric geophones measuring vibration acceleration, with built-in amplifier with extended frequency range up to 400 Hz. The A16HH and A05HH piezoelectric single- and three-component geophones are designed to convert the accelerations acting along their measuring axes into proportional electric signals. The A05HH geophone is designed to measure signals at lower levels than the A16HH. The sensing elements are connected to preamplifiers, which form the main characteristics of the seismometers (frequency response, conversion factor, voltage, output impedance, etc.), which allows you to adapt the geophones to solving a specific measurement problem. The geophones have a built-in electrical monitoring system. The monitoring signal passes directly through the sensitive elements, which allows for electrical monitoring of the through path.
Seismometers and geophones are used in geophysical equipment, seismic stations, geophysical research and exploration
