Nominal sensitivity in V/m/s**2 is
The responses here apply to the uniaxial (1), triaxial (3), and borehole (BH) versions.
Note: The RT131A-02 was initially manufactured using the SF3000L 2-pole analog filter. Subsequently, the SF1500S filter was substituted. There should be a plate or decal on the side of the accelerometer that tells you which type of filter was used. If not, it probably uses the SF3000L filter.
