Other potential applications for pneumatic controls are in industrial applications. The sensor may be used to both monitor and control pneumatic flow and system pressure for precise and efficient performance. Some pneumatic pumps, valves, and actuators contain integrated pressure sensors. Pressure sensors are also placed throughout other points of the pneumatic circuit in many industrial systems. Analytical devices for weather, air quality, and contaminants also make use of pneumatic controls for consistent and accurate sampling. Some specific potential industrial applications would include: precise sampling or gas flow for barometry, gas chromatography, or analytical instrument sampling systems; pneumatic systems for HVAC transmitters, automated pneumatic assembly equipment, pneumatic operator control systems; pneumatic components for valves, pumps and actuators; and gas collection or delivery for industrial gas supply.
