摘要： A pressure control system for maintaining pressure of a gas within a container at a preselected value. The volume within the container is connected to a source of pressurized gas. An external portion of the container is spherical shaped and has an orifice formed therein through which gas is exhausted from the volume. A piezoelectric bender bimorph has a portion thereof adjacent the exhaust orifice. Feedback means connected between the volume and the piezoelectric bender bimorph function to vary the position of the bimorph relative to the exhaust orifice to maintain pressure within the container at preselected value.

摘要： The balancing-vessel transducer disclosed consists of a structure (7) enclosing two intercommunicating chambers (1, 2) part-filled with a liquid (4), and made freely rotatable about a horizontal axis (3) coinciding substantially with its centre of mass. One chamber (1) is in receipt of a pneumatic signal, whilst the other chamber (2) is held at a constant reference pressure, such that liquid is displaced from one chamber to the other, thereby occasioning a redistribution of mass; the structure responds by rotating, its movement being checked by a force of reaction that varies in proportion to the force of the pneumatic signal, and turns through an angular distance that can be sensed in the shift of an eccentric pin (5) attached to the structure itself.

摘要： An electro-pneumatic control system (10) provides closed-loop control of a DC motor (12) which is operated from a biased motor servo circuit (14) thereby eliminating the need for a negative power supply to provide bi-directional rotation. Closed loop control is provided by a feedback signal from a pressure transducer (26) monitoring a pressure output signal (22) of a mechanical servo assembly (20).

摘要： A magnetic actuator (15) for providing mechanical actuation representative of an input electric current has a housing (25) that supports a coil (40) surrounding a central core (26), and includes a diaphragm type spring (35) above the central core (26). A cover of high magnetic permeability (39) is mounted on the housing (25) spaced from the diaphragm spring (35). A permanent magnet (42) is mounted on the diaphragm spring (35) in a predetermined pole orientation and the magnet (42) extends through an opening (43) in the cover (35). The permanent magnet (42) provides flux through the housing (25) and the core (26). Sensitivity is increased by using the permanent magnet (42) to provide a magnetic flux in addition to that created by currents in the coil (40). The magnet (42) is oriented in relation to current flow in the coil (40) so that the flux from the magnet (42) will add to that generated by the coil (40) in the gap (38) between the pole face (31) formed by the core (26) and the spring (35) and will subtract from the flux generated by the coil (40) in the gap (45) between the spring (35) and the cover (39) to provide a substantially linear deflection versus current relationship.

摘要： A pnemuatic servo assembly (20) is provided for an electro-pneumatic control system (10) having closed loop control of a DC motor (12) operated from an error signal (56) developed from an electrical set point signal (40) and a pneumatic feedback signal (44). The feedback signal (44) is made compatible by a pressure transducer (26) monitoring a pressure output signal (22) of the pneumatic servo assembly (20) and establishing an electrical signal indicative thereof which is scaled, zeroed, and amplified by an amplifier unit (46).

摘要： The present invention entails a current to pressure (I/P) transducer for converting andelectric signal to a proportional pressure signal over a given span. Essentially the I/P transducer comprises a housing having a membrane with magnetic and metal properties extending across and over a seat area. An air supply inlet is provided within said housing as well as a pneumatic output port. Typically, at least a portion of the inlet air supply is directed between the seat and membrane and out the output port. The pressure of the fluid passing from the output port becomes the produced proportional pressure signal of the I/P transducer. Wire windings are disposed within the housing about a core, and two poles of opposite polarity are disposed on opposite sides of the membrane. An input current signal directed through the wire windings results in a magnetic force acting on the magnetic membrane and effectively loading the membrane. The resulting magnetic force acting on the membrane directly affects the pressure of the pneumatic output signal since the loading of the membrane acts to restrict flow between the seat and membrane. By appropriately adjusting the I/P transducer and particularly the fluid flow therethrough, the output fluid pressure signal is maintained proportional to an input current signal directed through the wire windings.
摘要翻译：本发明涉及一种用于在给定跨度上将电信号转换成比例压力信号的电流（I / P）换能器。基本上，I / P换能器包括壳体，该壳体具有在座位区域上延伸和延伸的具有磁性和金属特性的膜。在所述壳体内设有供气入口以及气动输出口。通常，入口空气供应的至少一部分被引导在座和隔膜之间并且从输出端口出来。从输出端口流出的液体的压力成为I / P换能器产生的比例压力信号。电线绕组围绕芯设置在壳体内，并且相反极性的两极设置在膜的相对侧上。通过线绕组的输入电流信号导致作用在磁膜上的磁力并有效地加载膜。作用在膜上的所得磁力直接影响气动输出信号的压力，因为膜的加载用于限制阀座和膜之间的流动。通过适当地调节I / P换能器，特别是通过其中的流体流动，输出流体压力信号与通过导线绕组的输入电流信号保持成比例。
