  • Publication number: 20190234173
    Abstract: A rotating control device includes a housing with a sensor port extending to a central housing bore, a sensor in the port, and a rotating sleeve assembly (RSA) extending within the central bore. The RSA includes a sleeve configured to rotate relative to the housing and a second bore coaxially aligned with the central bore of the housing, A piston port in the sleeve extends to the second bore, and a piston disposed in the piston port is configured to reciprocate between a first position and a second position in response to a change in pressure of fluid within the second bore. The piston port and the piston are disposed at a location in the rotating sleeve that passes the sensor periodically when the rotating sleeve rotates; the sensor configured to detect the piston when it rotates past the sensor and is in its second position.
