    摘要： An electronic regulator includes an inlet valve coupled to an inlet port, the inlet port configured to receive a supply pressure, and an exhaust valve coupled to an exhaust port, the exhaust port configured to release a pilot pressure when the exhaust valve is open. The electronic regulator also includes a pilot pressure output pneumatically coupled to the inlet valve and exhaust valve and configured to be coupled to an external process control device to provide the pilot pressure to the external process control device. A setpoint input coupled to both the inlet valve and the exhaust valve receives a setpoint signal indicative of a setpoint value, and the electronic regulator operates the inlet valve and the exhaust valve to control the pilot pressure according to the setpoint value. Further, the electronic regulator includes a vent valve coupled to a venting port and pneumatically coupled to the pilot pressure output. The venting port is configured to release the pilot pressure according to the safety control signal.

    摘要： This disclosure is related to a non-electronic pressure control system for a pressurized system that receives fluid from a fluid supply. The pressure control system includes a control module, an actuator and a flow control device. The control module monitors the pressure of fluid either upstream or downstream of the flow control device. The control module can send a pneumatic signal to the actuator to open or close the flow control device responsive to the pressure monitored by the control module and the pressure required for the pressurized system.

    摘要： Regulator for precision control of pressure based on a means of measuring pressure differentials. More specifically, the present invention provides a pressure control that tracks a relatively high background pressure, and applies a positive or negative offset to create the small pressure differentials that can be utilized to transport fluids within a capillary network. The present invention is also directed to a method of controlling microfluidic elements (such as donut cavities) with a high degree of precision. In high performance liquid chromatography applications, this is accomplished using tracking pressure regulators to measure and respond to the difference between the liquid pump pressure and the regulated pneumatic pressure.

    摘要： A process and installation for the regulation of the vacuum level prevailing in a network of vacuum conduits in a hospital building comprises one or several vacuum pumps connected pneumatically to the vacuum conduits (CV); elements (C2) for determining the pressure to determine the underpressure prevailing in the vacuum conduits (CV); a pilot device (MP) controlling at least one vacuum pump, at least one line for connection to the atmosphere (L1, L2) having a first end connected pneumatically to the vacuum conduits and having a second free end; and control elements (EV1, EV2) for the flow of fluid arranged in the line for connection to the atmosphere (L1, L2) to permit controlling the passage of air in the line connecting to the atmosphere.
