Abstract
A pressure calibration system includes a manual pump and pressure adjustment subsystem. The pump outputs pressurized fluid to the adjustment subsystem in response to manual actuation. The adjustment subsystem is configured to automatically adjust the pressure in fine increments after the manual pump pressurizes the fluid within a tolerance range of a pressure set point. A user interface is further configured generate annunciations regarding the fluid pressure.
Claims18
A pressure calibration system, comprising:
- a manual pump configured to receive a fluid from a fluid source and output the received fluid in response to manual actuation of the pump by an operator;
- a pressure adjustment subsystem including:
- a manifold including a plurality of channels extending between an inlet and a first outlet, wherein the inlet is in fluid communication with the pump for receipt of the fluid and the first outlet is configured for fluid communication with a pressure vessel;
- an adjustable chamber in fluid communication with the plurality of channels and includes an actuator configured to move so as to increase or decrease the adjustable chamber volume in response to receipt of a command signal;
- at least one first pressure sensor configured to measure a manifold pressure of the fluid received within the manifold from the manual pump and output a manifold pressure signal representing the measured manifold pressure;
- and
- a pressure controller including at least one processor and configured to:
- receive the manifold pressure signal from the at least one first pressure sensor;
- output a first notification signal when the manifold pressure is within a first tolerance range about a pressure set point and outside of a second tolerance range about the pressure set point, the first notification signal representing an instruction for the operator to cease manual actuation of the manual pump;
- transmit at least one first command signal to the adjustable chamber following output of the first notification signal,
- wherein, when the manifold pressure is less than the pressure set point, the first command signal is configured to command the actuator to move and decrease the adjustable chamber volume, and
- wherein, when the manifold pressure is greater than the pressure set point, the first command signal is configured to command the actuator to move and increase the adjustable chamber volume;
- and
- a user interface in electrical communication with the pressure adjustment subsystem and configured receive notification signals from the pressure adjustment subsystem and to generate corresponding annunciations.

A method of pressure calibration, comprising:
- receiving, by a manual pump, a fluid received from a fluid source;
- outputting, by the manual pump in response to manual actuation by an operator, the received fluid to an inlet of a manifold, the manifold including a plurality of channels extending between the inlet and a first outlet configured for fluid communication with a pressure vessel;
- measuring, by at least one first pressure sensor, a manifold pressure of the fluid received within the manifold from the manual pump;
- outputting, by at least one first pressure sensor, a manifold pressure signal representing the measured manifold pressure;
- receiving, by a pressure controller including at least one processor, the manifold pressure signal;
- outputting, by the pressure controller, a first notification signal when the manifold pressure is within a first tolerance range about a pressure set point and outside of a second tolerance range about the pressure set point, wherein annunciation of the first notification signal represents an instruction for the operator to cease manual actuation of the manual pump;
- transmitting, by the pressure controller, at least one first command signal to an adjustable chamber following output of the first notification signal, wherein the adjustable chamber includes an actuator configured to move so as to increase or decrease the chamber volume in response to receipt of the at least one first command signal;
- wherein, when the manifold pressure is less than the pressure set point, the first command signal is configured to command the actuator to move and decrease the chamber volume, and
- wherein, when the manifold pressure is greater than the pressure set point, the first command signal is configured to command the actuator to move and increase the chamber volume;
- and
- generating, by a user interface in response to receipt of notification signals from the pressure controller, annunciations corresponding to received notifications.
