Abstract: A sensing system configured for use in a borehole is provided. The sensing system includes: a body portion; a clamp arm engaged with the body portion, the clamp arm configured to move between (i) a retracted position for lowering the sensing system into the borehole, and (ii) an extended position for locking the body portion in place after being lowered into a position within the borehole; and a dissolvable element for securing the clamp arm in the retracted position until the dissolvable element reacts with an environment in the borehole such that the dissolvable element sufficiently dissolves, thereby allowing the clamp arm to move from the retracted position to the extended position.
