Abstract
Example aspects of an over-pressure protection system and a method for operating an over-pressure protection system are disclosed. The over-pressure protection system can comprise a main body housing defining a main body chamber; a fluid received in the main body chamber, the fluid defining a fluid pressure; a pressure sensor configured to measure the fluid pressure of the fluid, the pressure sensor configurable in an activated mode and a deactivated mode; and a control system configured to place the pressure sensor in the deactivated mode when the fluid pressure is equal to or above a pre-determined threshold pressure.
Claims21
An over-pressure protection system comprising:
- a main body housing defining a main body chamber;
- a fluid received in the main body chamber, the fluid defining a fluid pressure;
- a pressure sensor configured to measure the fluid pressure of the fluid, the pressure sensor configurable in an activated mode and a deactivated mode;

A method for operating an over-pressure protection system comprising:
- coupling the over-pressure protection system to a pipeline, the pipeline defining a pipeline pressure, the over-pressure protection system comprising a pressure sensor;
- measuring the pipeline pressure with the pressure sensor;
- and
- deactivating the pressure sensor when the pipeline pressure is equal to or above a threshold pressure;
- wherein:
- the over-pressure protection system further comprises a main body housing, the main body housing defining a main body chamber, an incompressible fluid received in the main body chamber;
