ABSTRACT:
A non-contact type ring setter uses a pressurized gas operated sensor comprising two nozzles, each having an elongated opening for passing the pressurized gas. The openings are spaced apart and opposite to each other. A drill bit is moved relative to a collar, with the line of travel of the drill bit passing through the space between the two openings. Each of the elongated openings has a longitudinal axis substantially parallel to the direction of travel of the drill bit. When the collar and the drill bit are moved relative to each other a predetermined amount, the gas pressure detected by the sensor changes.
