20090133573 | METHOD FOR IDENTIFICATION OF THE DRIVE TYPE OF AN ACTUATING DRIVE - The disclosure relates to a method for identification of the drive type of an actuating drive, e.g., a pneumatic actuating drive, having a position regulator in order to control an actuating member in a process installation. The actuating drive is connected by means of an attachment to the position regulator, with the position regulator having control electronics which receive one or more input signals with the aid of a microcontroller and emit actuating signals in order to ventilate or vent the chambers of a single-acting or double-acting pneumatic drive. The position feedback sensor system is equipped with a rotational measurement system. The actuating range of the actuating drive is passed through completely while setting it up. The angle positions signaled back are recorded. The drive type is determined from the range between the limit angle positions at the actuating range limits of the actuating drive. The knowledge that the angle ranges covered by linear-movement drives and pivoting drives differ significantly can be made use of. | 05-28-2009 |
20090145291 | METHOD FOR DETECTING THE DRIVE TYPE OF AN ACTUATOR (II) - A method is disclosed for detecting the drive type of an actuator, e.g., a pneumatic actuator, having a positioner for operating a final control element in a process engineering plant. The actuator is connected to the positioner by a mounting set, the positioner comprising an electronic control unit, which uses a microcontroller to receive one or more input signals, and to output actuating signals to control the flow of gas to or from the chambers of a single-acting or double-acting pneumatic drive. The position feedback sensors are equipped with a rotational measuring system. During commissioning of the actuator, the relationship between the drive volumes and the position signal is found and compared with transfer characteristics of known drive types. Where there is a match between the transfer characteristic defined by the value pairs of the given actuator and one of the transfer characteristics of the known drive types, the identified drive type is assigned to the given actuator. | 06-11-2009 |
20100147079 | MEASUREMENT DEVICE AND METHOD FOR DIAGNOSIS OF NOISE IN FLUIDIC SYSTEMS - A measurement device and method for diagnosing noise in fluidic systems. A microphone, which is arranged at least partially in the area of the flow medium, compensates for pressure surges in the flow medium. The microphone receives the noise via a membrane and converts it to an electrical signal for evaluation of the noise source by an electronic diagnosis unit. To compensate for pressure surges in the flow medium, the membrane of the microphone is arranged in a housing, which is open on both sides of the membrane and whose two openings have pressure applied to them by the flow medium as a sound source, with at least one of the two openings being provided, in order to detect noise, with filter means for attenuation and/or time delay of frequencies which are in an expected noise spectrum, while the filter means allows lower frequencies produced by the pressure fluctuations in the flow medium to pass through. | 06-17-2010 |
20100179697 | METHOD FOR POSITION-DEPENDENT ELECTRONIC WEAR STATE DETERMINATION OF A VALVE MECHANISM, AND A PNEUMATIC VALVE - A method and a valve arrangement are provided for electronic wear state determination of the valve arrangement for controlling a process medium flow. A valve element, which is arranged so as to move axially within a valve housing, is moved via electrically drivable linear drive means on the basis of positioning regulation. The valve element has an essentially constant drive force applied to it, and a position speed profile over the switching travel of the valve element is determined by detecting the speed as a function of the current position of the valve element. A change profile is created by comparing the determined speed profile with previous position speed profiles, as a measure of the position-dependent wear state of the valve mechanism. | 07-15-2010 |
