Geophone MTSS-2003

A compact-size velocimeter MTSS-2003 combines a low-noise, light weight and high gain. The electrodynamic feedback results in a very flat response over a wide frequency range, high dynamic range and high time and temperature stability of the instrument's parameters. 

The wide dynamic range, high temperature stability and competitive price make it ideal and cost-effective for various applications such as earthquake measurements, structural health monitoring and others.

This model uses the same layout, sensing cells and electronic circuitry as those of MTSS-1043A. The output function is formed by a feedback configuration. 

A low-frequency version MTSS-2003WB has a bandwidth of 0.2 - 20 Hz.

The MTSS-2003 frequency characteristic with the poles and zeros presentation is available at the link of the website of Incorporated Research Institutions for Seismology (IRIS).
