Pressure sensor calibration valve for improving zeroing calibration of pressure sensors

Abstract

Examples of the present application provide pressure sensor calibration valves for improving zeroing calibration of pressure sensors. For example, an example pressure sensor calibration valve includes a valve body having a vent port, a rotatable handle connected to a pinion gear positioned in the valve body, and a sealing component connected to a linear rack that engages with the pinion gear. When the rotatable handle is at a sensing position, the sealing component is biased to seal a vent port opening of the vent port. When the rotatable handle is rotated from the sensing position to a venting position, the sealing component is displaced away from the vent port, and an electrical signal is triggered to initiate the zeroing calibration of the pressure sensor.
