MAGNET AND SENSOR CAP OF A ROTATIONAL CONTROL DEVICE |
摘要 |
A rotating control device (RCD) sensor assembly is provided. The rotating control device sensor assembly includes an emitter disposed on a rotational component of a rotating control device, wherein the emitter emanates a detectable signal field, a cap coupled to the rotational component to form a volume between the cap and the rotational component, wherein the emitter is enclosed within the volume, and wherein the cap is made of a transmissive material, and a sensor that detects the signal field through the cap as the emitter passes within a proximity of the sensor. |
