We develop and produce microelectronic (based on Silicon-on-Sapphire structures) pressure transducers and transmitters. Pressure ranges from 4 kPa to 160 MPa, accuracy from 0.1%FS to 1%FS, output from 5 mV/V to 10 mV/V (for transducers), 4-20 mA, 0-5 mA, 0-5 V for transmitters. Temperature range of measured media -40...80 C (industrial version) and from -200 to 500 C (special versions). Intrinsic-safe and explosion-proof versions; transmitters for atomic power stations. Among special types: pressure transducers/transmitters for melts (up to 350 C), diesel control (up to 500 C), downhole transducers for oil pits, etc. Also power supplies, including intrinsic-safe version, intrinsic-safe digital indicators of pressure or temperature, surge-protection devices.
