摘要： A system and method for controlling at least one hydraulic actuator of a hydraulic system includes a flow rate measurement of a hydraulic fluid flow traveling into and out of a cavity of the hydraulic actuator. The flow rate is used to calculate piston information corresponding to a position, velocity, acceleration, and/or direction of movement of a piston of the hydraulic actuator. The piston information can then be provided to an output device to aid in the control of the hydraulic actuator. Alternatively, the piston information can be compared to a reference signal relating to a desired position, velocity, acceleration, and/or direction of movement of the piston to produce a control signal, which can be used to adjust the hydraulic fluid flow and provide the desired actuation of the piston.

摘要： Disclosed is a bi-directional differential pressure flow sensor that is configured to establish a direction and flow rate of a fluid flow. The flow sensor includes a flow restriction member, a differential pressure sensor, and processing electronics. The flow restriction member is configured to produce a pressure drop when placed inline with the fluid flow. The differential pressure sensor is embedded or integral with the flow restriction member and produces a differential pressure signal that is indicative of the pressure drop. The processing electronics produces a flow rate signal that is indicative of the direction and flow rate of the fluid flow as a function of the differential pressure signal.

摘要： A pressure measurement device comprising an absolute pressure sensor and a bus coupling serial communication and energization to an electrical connector in a field wiring compartment. An atmospheric pressure sensor module is connected to the bus at the electrical connector. The bus provides the energization to the atmospheric pressure sensor module and the bus receives a serial communication signal from the atmospheric pressure sensor module. The serial communication signal includes numeric data representing atmospheric pressure. The pressure measurement device provides a gage pressure output as a calculated difference between the sensed absolute pressure and the received numeric data.
