Seismic vibration sensor of special purpose PP075
A small - scale seismic vibration sensor, developed on the basis of filamentous silicon crystals, is used as a means of detecting moving ground objects, including moving, such as personnel, armored vehicles, as well as to determine the coordinates of the target, direction and speed of movement.
Main characteristics of development
Measurement range: ± 1, 2 g.
Conversion factor: 6 V / g.
Frequency range: 0 - 800 Hz.
Dynamic range (in the 100Hz band): 100 dB.
Temperature range: from - 60 to + 100 С.
Nonlinearity: ± 0. 15% .
Power supply: 6 - 15 V.
Weight: 350 g
Main advantages of development
Advantages of the development are: high mechanical strength of filamentous silicon crystals; radiation resistance to irradiation by electrons with an energy E ≤ 10 MeV; weak dependence of the output signal of the sensor from the magnetic field to 14 T.
A seismic vibration sensor can be used to protect important objects, detect moving objects, determine the type (classification) and estimate their coordinates, as well as to create systems that operate under strong electromagnetic fields.
