ABSTRACT:
An insertion regulator for insertion into and retraction from a pressurized pipeline and the like includes a sensor probe housing structure that is adapted for sealed connection at an aperture formed in the pipeline. The probe housing defines a probe receptacle opening into the pipeline. A sensor probe extends through the probe housing with an inner portion thereof in communication with the pressurized fluid medium within the pipeline. The inner extremity of the sensor probe is inserted into the pipeline against the influence of pressure contained therein by means of an actuator system employing a piston actuator that is movable responsive to pressure communicated thereto from the pipeline. The inner extremity of the probe is positionable at a preselected position within the pipeline for optimum sample taking and is retractable to a protected, noninterfering position within the probe receptacle to permit the passage of pigs and other objects through the pipeline.
