Abstract
Differential pressure sensors, control, and associated methods are disclosed. An example apparatus includes a first housing including a first port, the first port fluidly coupled to a first location, first fluid to flow into the first port from the first location, a second housing coupled to the first housing, the second housing including a second port, the second port fluidly coupled to a second location, second fluid to flow into the second port from the second location, and a piston slidably disposed between the first and second housings, the first and second fluids to cause movement of the piston, the movement of the piston corresponding to a differential pressure between the first and second locations.
Claims13
An apparatus to measure differential pressure, the apparatus comprising:
- a first housing including a first port, the first port fluidly coupled to a first location, first fluid to flow into the first port from the first location;
- a second housing coupled to the first housing, the second housing including a second port, the second port fluidly coupled to a second location, second fluid to flow into the second port from the second location;
- a piston slidably disposed between the first and second housings, the first and second fluids to cause movement of the piston, the movement of the piston corresponding to a differential pressure between the first and second locations;
- and
- a pneumatic valve operatively coupled to the first housing, the pneumatic valve to move to an open position when the differential pressure is at or above a pressure threshold.
An apparatus to measure differential pressure, the apparatus comprising:
- means for providing a first port fluidly coupled to a first location, first fluid to flow from the first location into the means for providing the first port;
- means for providing a second port fluidly coupled to a second location, the means for providing the second port coupled to the means for providing the first port, second fluid to flow from the second location into the means for providing the second port;
- means for translating slidably disposed between the means for providing the first port and the means for providing the second port, the first and second fluids to cause movement of the means for translating, the movement of the means for translating corresponding to a differential pressure between the first and second locations;
- and
- means for controlling air flow therethrough operatively coupled to the means for providing the first port, the means for controlling air flow therethrough to move to an open position when the differential pressure is at or above a pressure threshold.
