  • Method and apparatus for remote monitoring of valves and valve operators
    Patent number: 5000040
    Abstract: A method and apparatus for providing a previously unattainable yet desirable function of monitoring at a remote location and/or in a remote (non-intrusive) manner the condition of a valve operator to signal a need for more thorough inspection and for possible maintenance of the valve or valve operator; the method and apparatus including the relating of power parameters such as motor power and motor power factor to the valve operator stem load, setting up a control value for the power parameter based on a maximum allowable operator thrust depletion; and periodically monitoring actual power parameter values at a remote location for comparison to the control value.
    Type: Grant
    Filed: December 6, 1989
    Date of Patent: March 19, 1991
    Assignee: Movats Incorporated
    Inventors: Arthur G. Charbonneau, Stanley N. Hale, Edmond A. Sayed

  • Switch position sensing device for use with valve operators
    Patent number: 4672310
    Abstract: A switch position sensing device gives visual and recorded information as to the relative open and closed position of a monitored switch whether the monitored switch is found within an AC or DC circuit or a dead circuit and without disturbing the wiring of the switches primary circuit.
