A recently granted patent (Publication Number: US11885217B2) discloses an assembly designed to monitor seals in a system comprising two tubular elements. The assembly includes a primary seal, a secondary seal, and a seal monitoring apparatus with a housing and a position sensor. The housing features a chamber divided by a separator into a first sub-chamber connected to the seal cavity and filled with hydraulic fluid, and a second sub-chamber filled with compressible fluid. The position sensor generates an electrical signal representing the separator's position relative to the housing, aiding in seal monitoring.

Furthermore, the assembly includes features like a floating piston separator, a vent port connecting the second sub-chamber to the atmosphere, and a conduit linking the first sub-chamber to the seal cavity. The seal monitoring apparatus can transmit signals to a remote processor, and a restrictor device can control the separator's movement. Additionally, a resilient biasing element exerts force on the separator to facilitate its motion. The patent also covers applications in drilling installations and methods for monitoring seals and loading in such assemblies, showcasing the versatility and practicality of the innovation.
