Below is some model-specific information to help you locate your instrument response.

GS-13

This sensor measures ground velocity.

S-13

This sensor measures ground velocity. Responses were calculated using an empirical open-circuit damping factor of 0.007 measured at GFZ in Potsdam.

S-13J

This sensor measures ground velocity.

BB-13

This sensor measures ground velocity.

KS-2000

This sensor measures ground velocity. This manually centered model has the same response as the KS-2000M and KS-2000BH.

KS-2000M

This sensor measures ground velocity. This motor-centered model has the same response as the KS-2000 and KS-2000BH.

KS-2000BH

This sensor measures ground velocity. This borehole model has the same response as the KS-2000 and KS-2000M.

S-230

This one-component sensor measures ground acceleration. It has the same response as the PA-23 and PA-23BH

PA-23

This three-component surface sensor measures ground acceleration. It has the same response as the S-230 and PA-23BH

PA-23BH

This three-component borehole sensor measures ground acceleration. It has the same response as the S-230 and PA-23.
