摘要： A diagnostic test unit for deterministically measuring one or more parameters, such as dead band, dead time, response time, gain, or overshoot, of a process control device that is connected in a process control loop during operation of a process includes a switch controller, a signal generator, a switch, a response accumulator mechanism, and an analyzer mechanism. The switch controller monitors a process signal during operation of the process to determine whether the process signal is substantially stable. In the event that the process signal is substantially stable, the switch replaces a control signal with a diagnostic test signal generated by the signal generator. The response accumulator is in communication with the process control loop to obtain an indication of the response of the process control device to the diagnostic test signal. The analyzer unit then determines the device parameter from the test signal and the response indication.

摘要： An apparatus for nonobtrusively determining one or more parameters, such as dead band, dead time, or response time of a process control device that is connected on-line in a process control loop includes a measurement unit and a processing unit. The measurement unit is coupled to the process control loop to detect stochastic changes in a control signal sent to the process control device and to detect an indication of the response of the process control device to the changes in the control signal while the process control device is operating on-line. The processing unit calculates the device parameters from one or more sets of the detected changes in the control signal and the detected response indication.

摘要： Disclosed herein is a controller and method useful for transferring control of a process control device between first and second control modes. The controller includes first and second servo control modules that generate first and second drive signals based on feedback information from first and second sensors for control of the process control device in accordance with first and second control modes, respectively. The controller also includes a feedback control transfer module that transfers control of the operation of the process control device from the first control mode to the second control mode based on the feedback information from the first sensor. In certain embodiments, such control transfer involves a control routine that initially generates the second drive signal based on the first drive signal to effectuate a smooth, bumpless transfer between the control modes.

摘要： A device intended to meet flameproof approval requirements is configured to have two compartments separated by an energy-limiting barrier. The first compartment of the device houses the wiring terminations that bear ignition-capable energy and, therefore, must be flameproof. The energy-limiting barrier is configured to limit the energy that can reach the second compartment to a level that is not ignition capable. This allows the second compartment to be safe without meeting the flameproof requirements, and allows user-interface elements such as switches and indicators to be designed in a more cost-effective manner.

摘要： A multi-functional or versatile emergency shutdown valve controller may be used in various different emergency shutdown configurations to enable the testing of different types and configurations of emergency shutdown devices and the supporting equipment associated therewith. In one example, a digital valve controller for use with an emergency shutdown valve includes two pressure sensors and is adapted to be connected to a pneumatic valve actuator and to a solenoid valve device to assist in the on-line testing of the valve actuator as well as in the on-line testing of the solenoid valve. To perform testing of the solenoid valve, the valve controller may measure the pressure at different ports of the solenoid valve as the solenoid valve is actuated for a very short period of time. The valve controller may determine whether the solenoid device is fully functional or operational based on the derivative of the difference between the measured pressure signals, i.e., based on the rate of change of the difference between the measured pressure signals over time.
