MBA2.2/3.2 "TYPE MAIHAK" Paddle Measure Indicator ATEX


"MAIHAK" Rotating Paddle Measure-Indicator

The MBA2.2 and MBA3.2 devices are ATEX-certified rotary paddle level indicators, which are used in dust explosion zones 20 with gas explosion zone 1 and impress with their robust design.

The MBA2.2 (vertical version) as well as the MBA3.2 (horizontal version) are particularly suitable for measuring the limits of granulate, dust or sludge.

A measuring paddle is driven by a synchronous geared motor, which stops as soon as it is covered by filling material. A reduction in the fill level releases the rotating paddle.



    Device head IP 65 made of extremely robust gray cast iron, MBA3.2: angle bracket reinforced by additional ribs


    2 speed versions; different supply voltages; MBA2.2 also with flexible steel cable shaft or with protective tube; optional with angled flange


Both the MBA2.2 and MBA3.2 level indicators have ATEX certification for Zone 20 and Zone 1, making them your safe choice in areas where there is a risk of explosion from dust and gases.

The typical application areas of the MBA2.2 and MBA3.2 are therefore silos and containers, which contain bulk solids that evaporate combustible gases or vapors, e.g. wood shavings containing glue or paint, plastic granules, chemical products or sewage sludge.


  • Pressure stages up to PN 16
  • Operating temperatures up to 350°C
  • Both device versions have ATEX approval for dust explosion zone 20 (II 1/2 D IP 65 T) and gas explosion zone 1 (II 2G Ex de IIC / IIB T1 / T2 / T3)
