Multi - limit sensors E'lemer AIR-20M2-H

Microprocessor-based multi-limit pressure sensors with HART protocol with improved metrological and functional characteristics. One of the most popular sensors in the line of NPP "ELEMER", having a wide range of models. The sensors are designed for continuous conversion of absolute pressure, overpressure, overpressure-vacuum, differential pressure, hydrostatic pressure into a unified output current signal of 0...5 mA or 4...20 mA and/or a digital signal in the standard of the HART protocol. The device also has a dual combined current output of 0...5/4...20 mA. The sensors have a built-in LED indicator (SD) with the possibility of discrete rotation at an angle of 90°, 180° and 270°. The case rotates smoothly at — 270°. The sensors have a built-in 3-button menu on the front panel of the indicator for the possibility of setting and editing parameters, as well as for calibration and obtaining diagnostic data. The sensors have high noise immunity — EMC group — IV-A(B).
