Development and experimental testing of a method of checking thermoelectric alternating-voltage transducers

A block diagram of an automated workstation based on controlled devices for testing thermoelectric voltage transducers is presented.Translated from Izmeritel'naya Tekhnika, No. 7, pp. 56–57, 1994.     

Main problems of the unification and standardization in developing special purpose displacement transducers

The main problems of unification that arise in the development of special purpose displacement transducers are formulated. Ways are considered for resolving these problems, and the main concepts and definitions used in unification and standardization of transducer equipment are provided. Translated from Izmeritel’naya Tekhnika, No. 12, pp. 56–58, December, 2008.     

New transducers for high-resolution ultrasonic testing

High resolution NDT requires ultrasonic transducers which can produce very short pulses with well-defined constant shape throughout the field. The theory, construction and applications of such transducers are discussed.     

New equipment for checking heat-power instruments

Summary The first specimens of the described apparatus were produced by the Etalon Plant of the VNIIM in high-temperature performance, and they were thoroughly tested. Thanks to their compactness, convenience in operation, and high checking accuracy, the apparatuses will undoubtedly find a wide application in the laboratories of the Committee system and in control laboratories of metallurgical plants.The process of testing with both apparatuses is considerably speeded up thanks to a rational selection and arrangement of standard measuring instruments built into the apparatus, switching and regulating devices, and also thanks to the application of the semi-automatic standard R2-A potentiometer ZIP model.According to sources in literature, an apparatus for testing secondary instruments has not been developed abroad.The drawings of the apparatus are presently being handed over to a number of organizations in order to bring about its production in series.
