Seismic sensor Wilcoxon Research

Combine a supersensitive piezoelectric accelerometer, an ultra low-noise amplifier, excellent electrical/mechanical isolation, and the result will be unmatched performance in measuring low-level vibration.

The 731A ultra-quiet seismic accelerometer can measure vibration levels down to the sub micro-g range by using an ultra low noise internal amplifier and a high sensitivity inertial sensing element. It contains no moving parts, is not sensitive to magnetic fields, and has a relatively low mass.

The P31 amplifier enhances the capabilities of the 731A by providing special low noise signal amplification and conditioning by providing 2.4mA constant current needed to power the accelerometer’s internal amplifier.

Some common applications include: earthquake detection, geophysics, geothermal development, structural analysis and mine safety.
