Description
SDV-SMART intelligent pressure transmitters are one of the best domestic universal solutions for pressure measurement, offering extensive functionality and built-in continuous self-diagnostic system of the device and the technological process.
The wide model range of SDV-SMART transmitters provides high-accuracy measurement of gauge pressure, absolute pressure, vacuum pressure and pressure-vacuum, differential pressure, and hydrostatic pressure.
SDV-SMART transmitters are equipped with modern Russian tenzo-resistive sensors manufactured using silicon-on-sapphire technology, ensuring high reliability, stable metrological characteristics, and operation at low temperatures without loss of response speed.
-
SDV-SMART transmitters with a 4–20 mA + HART unified current output signal are designed for continuous conversion of input measured values into a unified current signal and a digital HART® protocol signal. Loop integrity diagnostics detect current loop failures, reducing downtime and maintenance costs.
-
SDV-SMART transmitters with 0.8–3.2 V + HART unified voltage output signal are designed for continuous conversion of input measured values into a unified DC voltage signal and a digital HART® protocol signal.
-
SDV-SMART transmitters with RS485 digital communication are designed for continuous conversion of input measured values into a digital ModbusRTU protocol signal.
SDV-SMART transmitters are available in Non-explosion-proof option and Explosion-proof versions (including flameproof enclosure “d”, intrinsically safe electrical circuit “ia”, and combined explosion-proof designs).
They are intended for measuring pressure of liquids (seawater, oils, diesel fuel, fuel oil, kerosene, gasoline), steam, gases (including hydrogen sulfide, hydrogen, gaseous oxygen), steam-gas and gas mixtures (including oxygen-containing, hydrogen sulfide, and hydrogen-containing mixtures).
SDV-SMART transmitters can be supplied with valve blocks, cable entries, mounting brackets, adapters, plugs and fittings, separation vessels, and impulse lines.
Upon request, positional marking can be applied on a stainless steel nameplate, and housings can be painted in required RAL colors.
