ABSTRACT:
A stabilized insertion device to prevent harmonic vibration or "wiggle" when inserting a probe or sensor into a gas pipeline. A shaft guide is placed around the shaft inside the housing of the insertion device. The shaft guide is composed of two sections. The first section is wider than the second. The second section is received by a spool bushing located inside the housing proximate to the pipeline. When the shaft is fully extended the spool bushing holds the shaft guide steady which in turn holds the shaft steady. An annular bevel and taper may be added to the spool bushing and shaft guide, respectively, to aid in the coupling thereof. Optionally, the shaft guide may be bisected to make it movable to different positions on the shaft, thereby allowing for probe insertion at a variety of depths.
