Abstract
A seal support sensor includes a housing, an extension, a sensor and an electronic controller. The housing is configured to attach to a barrier fluid tank. The extension 64 has a distal end and a proximal end, the proximal end being connected to the housing. The sensor is disposed at the distal end, configured to be disposed within the barrier fluid tank and configured to detect a parameter within the barrier fluid tank. The electronic controller is configured to determine whether the parameter within the barrier fluid tank is within a predetermined range perform a mitigation operation when the parameter is not within the predetermined range.
Claims12
A seal support sensor, comprising:
- a housing attached to an external portion of a barrier fluid tank for a pump;
- an extension having a distal and a proximal end, the proximal end being connected to the housing;
- an electronic controller disposed within the housing and configured to determine whether a parameter within the barrier fluid tank is within a predetermined range, when the parameter is not within the predetermined range, the controller determines that a shut down of the pump is required and is configured to send a signal shutting down the pump based on the parameter detected within the barrier fluid tank;
- a capacitive level sensing probe configured to produce a level probe signal, the capacitive level sensing probe being an insulated spring steel rod coupled to a bracket at the distal end of the extension;
- and
- a pressure transducer configured to detect a pressure within the barrier fluid tank, the pressure transducer disposed entirely within a sealed cap at the distal end of the extension, the sealed cap including a seal configured to seal the cap from external elements.
