Title: SYSTEM FOR SENSING LEAKS IN A STUFFING BOX
Abstract:
The present invention relates to a leak sensor for stuffing boxes. In this connection, the present invention provides a system configured to sense a leak in a stuffing box, wherein the system comprises a sensing device comprising: a support supporting an elongated structure, wherein the elongated structure is configured to pivot relative to the support; a container fixed to a first end of the elongated structure, suitable for receiving liquid from a leak; and at least one position sensor suitable for detecting a position of the elongated structure, wherein the system is configured such that: when empty, the container remains in a raised position, and a second end of the elongated structure, opposite the first end to which the container is fixed, remains in a lowered position; and when filled with leaked liquid, the container moves to a lowered position compared to its empty raised position, and the second end of the elongated structure moves to a relatively raised position compared to its empty lowered position.
