  • Patent number: 11674611
    Abstract: Wear-resistant electro-pneumatic converters are disclosed. An electro-pneumatic converter includes a body including an axial passageway extending between a first opening and a second opening, the first opening associated with a supply port, the supply port to receive pressurized fluid from a pressure supply source, a solenoid disposed within the axial passageway, an armature including a first side and a second side opposite the first side, the second side facing the solenoid, the armature movable between a first position and a second position, the pressurized fluid blocked from flowing through the output port when the armature is in the first position, the pressurized fluid to flow through the output port when the armature is in the second position, and a spring coupled to the first side of the armature, the spring to bias the armature toward the first position.

  • Patent number: 10539251
    Abstract: A transducer for a connection to a fluid pressure source having a mechanism for setting a pneumatic output by way of an electrical input signal. The transducer provides a lower housing assembly and an upper housing assembly. The lower housing assembly comprises lower housing configured to receive a supply nozzle. The supply nozzle fluidly communicates with a supply port and intermittently fluidly communicates with an output port of the lower housing through an internal fluid passageway. The upper housing assembly comprises an upper housing configured to receive a coil and an armature such that the upper housing, coil and armature define a latching electromagnetic circuit that provides alternating contact of the armature with the supply nozzle of the lower housing assembly.

  • Patent number: 10352474
    Abstract: A transducer with a lower housing assembly and an upper housing assembly is for connection to a fluid pressure source having a mechanism for setting a pneumatic output via an electrical input signal. The lower housing assembly comprises lower housing configured to receive a supply nozzle, which fluidly communicates with a supply port and intermittently fluidly communicates with an output port of the lower housing through an internal fluid passageway. The lower housing further comprises an exhaust nozzle fluidly communicating with an exhaust port and intermittently fluidly communicates with the output port of the lower housing through the internal fluid passageway. The upper housing assembly comprises an upper housing configured to receive a coil and an armature such that the upper housing, coil and armature define a latching electromagnetic circuit that provides alternating contact of the armature with the supply nozzle and the exhaust nozzle of the lower housing assembly.

  • Patent number: 7190159
    Abstract: A non-contacting position sensor having primary and secondary sensors detects relative displacement between two objects. The secondary sensor may function as a limit switch detection element in a limit switch circuit, and is positioned to be in the path of magnetic flux not detected by the primary sensor. The primary sensor is positioned in a flux path between sections of a flux gathering pole. A secondary sensor is positioned in a leakage flux path outside the first sensor or may be positioned in a secondary flux path.
