Abstract
A capsule comprising two non-directly contacting halves enables otherwise coupling loads between experiment and gauging to be re-routed through the outer-most portable body (e.g. a logging sonde housing) having substantial inertia, thus serving to attenuate the parasitic loads. For co-located leveled experiment and gauging, a pair of concentric bearings (shaft in shaft) is utilized. Independent bearing sets and shock/vibration isolation support each capsule half within the outer sonde housing. A first half of the capsule supports the experiment, which the second half supports the gauging apparatus.
Claims10
A decoupling capsule for hosting ultra-sensitive experiments in a logging sonde, the capsule comprising:
- a first capsule member;
- a second capsule member, substantially encapsulating and physically isolated from said first capsule member;
- a payload area common to said first and second capsule members and configured to receive an experiment vessel;
- a first bearing pair in contact with said first capsule member defining a longitudinal rotational axis along said first and second capsule members;
- and
- a second bearing pair in contact with said second capsule member, along the longitudinal rotational axis.
