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 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.
