Abstract
A pressure measurement device is configured to adjust a gas pressure in an external gas cavity that is fluidly coupled thereto and measure the adjusted gas pressure in the external gas cavity. The pressure measurement device includes a port, a pressure control module, a port pressure sensor, and a gas discharging port. The pressure measurement device is fluidly coupled to the external gas cavity through the port. The pressure control module is coupled to the port through a gas passage and configured to operably provide pressurized gas to the external gas cavity or draw gas from the external gas cavity. The port pressure sensor is coupled to the port and configured to measure a gas pressure at the port. The gas discharging port is coupled to the port and the pressure control module, and configured to operably discharge gas from the port or the pressure control module to an external environment.
