Abstract:
An improved sensor assembly adapted to be received within a port defined by a component housing is provided. The sensor assembly includes a sensor element, a coupling, and a locking housing. The coupling includes a locking member configured for rotationally interlocking the coupling to the port. The locking housing defines a sleeve adapted to extend over the sensor element. The locking housing is adapted to prevent rotational movement of the coupling relative to the port when the coupling is interlocked with the port, thereby preventing disengagement of the coupling from the port.

A system for generating a chlorine-containing mixture comprises an anodic chamber comprising an anodic electrode and having an inlet for a first solution and an outlet for an anolyte solution. A cathodic chamber is spaced from and adjacent the anodic chamber in the system. The cathodic chamber comprises a cathodic electrode and has an inlet for a second solution and an outlet for a catholyte solution. The second solution may be the same as or different from the first solution, and at least one of the first and second solutions comprises a chlorinated solution.
