Abstract: The invention is a process tank containing a direct level magnetostrictive measurement system disposed directly in the tank, where the level system preferably communicates to a remote location. One embodiment of the invention embodies an internal well guide chamber, which exactly replicates the actual vessel's internal conditions (pressure and temperature), and also prevents the float from being affected by turbulence from a two phase condition, such as might occur if boiling or flashing is present inside the vessel. The process tank should have a fluid temperature different by more than 50° C. from the ambient environment, or alternatively, be a flashing tank.

Abstract: A method is provided for analyzing and diagnosing a large scale process automation control system having a plurality of control loops. Assessments for pre-defined key performance indicators (KPIs) are automatically generated for control, process and signal sections of each control loop. The automatically generated assessments of the pre-defined KPIs may be displayed in a graphical user interface (GUI) of a computer. A user may change the automatically generated assessments of the pre-defined KPIs. Different data views may also be displayed in the GUI. The data views include time series trends for measured process variable, controller output, controller set point and error, as well as controller parameter clustering views in two-dimensional and three-dimensional plots.

Abstract: A system for the detection of welded contacts in a circuit of a line converter system has a plurality of inverter switches, a plurality of utility switches in which a pair of utility switches is connected in series through a line to a utility, a voltage detector, an electronic controller, and a DC input source. The line converter system converts incoming DC power into AC output power that is delivered to the utility grid. The voltage detector measures the voltage across a first node and a second node of the circuit and provides an output that is interpreted by an electronic controller for each step performed during a method of detection of welded contacts. The detection method has a sequence of test steps in which at least one switch is opened and/or closed, a DC bus of the inverter or the utility grid is used as a stimulus voltage, and the voltage is measured. If a voltage is not detected across the first and second nodes, the test sequence is continued until a welded contact is detected or the electronic controller determines that none of the contacts are welded. If the controller determines that none of the contacts are welded, the line converter system is permitted to connect and supply AC power to the utility.

Abstract: A software product and method of monitoring a field device in an enterprise having an industrial process. A subscription to the OPC DA server for diagnostic data from the field device is made and a subscription to an OPC AE server for event notifications from the OPC AE server is made. The subscription to the OPC AE server is activated, but the subscription to the OPC DA server is not activated. When an event notification is received from the OPC AE server, the subscription to the OPC DA server is activated. Diagnostic data from the field device is received and device health information from the diagnostic data is generated. The device health information is displayed on a viewing monitor. The subscription to the OPC DA server is then deactivated.

Abstract: A current sensor is provided for non-invasively measuring electrical current in an electrical conductor. The current sensor includes a housing having a Hall effect device and circuitry for transmitting a signal indicative of the current flowing through the electrical conductor. The current sensor includes a base having a surface for supporting an electrical conductor. A magnetic shielding member is coupled to the surface to shield the Hall effect device from stray or external magnetic fields. A compliant member is coupled to the magnetic shielding member opposite the surface. The compliant member compresses to allow the current sensor to accommodate a large variety of electrical conductor sizes. The compliant member further acts to bias the electrical conductor against the Hall effect device.
