Intelligent pressure sensors ADD - SMART - reliable device, solves the problem of measurement excess (relative), absolute and differential pressures species, as well as vacuum and pressure - vacuum. Technologies sensors ADD - SMART create quality, stable device with high resistance to environmental factors.

Danish application methods in the oil industry, the power industry.

Calibration interval - 5 years.

Configuration and the inverter is controlled via digital indicators located on the housing and an indicator for remotely by a control device that supports the HART® protocol. There transient protection of communication lines, Welding equipment, heavy - duty work equipment and its mechanism of activation.
