The utility model provides a capacitive sensor probe. The capacitive sensor probe comprises an inner electrode, an outer electrode, a central electrode insulating sleeve and an electrode detection connecting sleeve, a central electrode insulating sleeve is sleeved outside the inner electrode; one end of the inner electrode extends out of the central electrode insulating sleeve and is arranged in an inner cavity of the electrode detection connecting sleeve; the outer electrode is of a hollow structure, the inner side wall of the tail end of the outer electrode extends inwards to form an outer electrode sealing protrusion, and an outer electrode inner thread is turned on the inner side wall of the outer electrode and located above the outer electrode sealing protrusion. According to the technology created by the utility model, two-section type connection is adopted, the safety performance is good, and oil, gas and water under pressure can be isolated at the outer electrode and cannot enter the sensor; the seali
