VNIIA has designed a wide range of pressure transducers and relays meant for automated I&C systems in petroleum, chemical and atomic industry
Pressure transducers are certified in the OIT System and are recommended for application at Gazprom facilities, they are included into the “Register” of the material and equipment types procured by AK Transneft. Transducers and relays have a conformity certificate in the GOST R System as explosion-proof equipment, and application permission from the Federal environmental, industrial and nuclear supervision service of Russia. The Institute has Licenses for design and manufacture of equipment for NPP, a certificate of conformance to the requirements of GOST R ISO 9001-2001 issued by the “Military Register” voluntary certification system.
Pressure transducers developed by VNIIA are used for measuring all kinds of pressure of liquids and gases: absolute excess, vacuum, etc.
They are remarkable for a wide range of pressures measured with high precision and stability, ease of operation, broad temperature range, explosion-proof version, and version for NPP.
The transducers are capable of transforming the measured value into a uniform current and/or digital signal.
Electronic modules for pressure transducers
Currently VNIIA is serially producing "smart" pressure transducers with better performance, achieved due to the recommendations from the operating organizations.
There is the common industrial version of transducers with explosion protection - "explosion-proof shell" for Gazprom, AK Transneft and other facilities of petroleum industry, and the version for NPP.
Smart pressure transducers for petroleum industry Smart pressure transducers for atomic industry
Smart pressure transducers successfully passed comparative tests together with sensors of other manufacturers at the operating NPP units and were included into the new NPP projects, since they demonstrated the best performance of all.
The specific features of smart pressure transducers are:
- output signal in digital form;
- remote control;
- LCD indicator;
- transducer self-diagnostics in the background mode;
- electronic board for lightning-protection in a stand-alone unit, which is easy to replace during operation.
The transducers and relays are produced serially in several versions. Currently, about 100 pressure transducers and relays are successfully operated at petroleum facilities, as well as Kalinin NPP, Kursk NPP, Novovoronezh NPP, Smolensk NPP, Balakovo NPP, Rostov NPP, Kola NPP, Bilibino NPP, and Bushehr NPP.
Equipping with VNIIA transducers is a part of the future NPP projects in Russia and abroad: Leningrad NPP-2, Novovoronezh NPP-2, Kursk NPP-2, Belarus NPP, Akkuyu NPP (Turkey).
Under the national program of import substitution, the scope of pressure transducers delivery to the main petroleum pipelines of Rosneft and Gazprom has been significantly expanded.
