MASS POSITIONING ADJUSTMENT MECHANISM FOR A SEISMIC SENSOR |
摘要 |
A mass position adjustment apparatus for use in a seismic sensor having axis mechanics including a pivotable boom with a defined null point is described. The apparatus comprising: (a) adjustment means for positioning the boom at the null point; (b) actuator means for moving the adjustment assembly; and (c) interface means having hard mineral members for interfacing the actuator means with the adjustment means for reducing occurrences of micro- mechanical movement when the mass position adjustment apparatus is not being operated.< /SDOAB>
