Abstract
A detection system includes a pressure sensor configured to contact an annular elastomer component of an annular BOP, wherein the pressure sensor is configured to generate a first signal indicative of a contact pressure with the annular elastomer component. The detection system also includes a piston stroke sensor configured to generate a second signal indicative of a piston stroke distance. The detection system further includes a controller configured to receive the first signal from the pressure sensor and the second signal from the piston stroke sensor and analyze respective changes in the contact pressure and respective changes in the piston stroke distance to determine a condition of the annular BOP.
