Bna11 / bna31-850 level gauge of pressurized oil tank / bna21-1000 / 25-2 magnetic flap level gauge
Bna21-1000 / 64 / 4-sc-mn magnetic flap level gauge bna21 this series of products have exquisite appearance and are polished; The magnetic unit uses the rubidium iron boron material used in the space station and adopts a special magnetic group structure. The magnetic beam is concentrated on the line plane with long-lasting strength; The output contact has magnetic memory function; Multi series selection, which can meet the requirements of different users:
Bna10 single pass series is suitable for liquid level measurement in non pressure occasions,
Bna20 two-way series is suitable for liquid level measurement of pressure vessels,
Bna30 top mounted series plug-in installation, convenient maintenance;
Optional photoelectric indicator board, photocell indicating liquid level, more eye-catching display, suitable for dark occasions; Optional two-wire transmitter, transmission controller and transmission controller can realize 4 ~ 20mA output.
1. Structure of magnetic flap level gauge
According to the buoyancy principle, the float moves up and down with the rise and fall of the liquid level in the measuring tube. The permanent magnetic steel in the float drives the red and white turnover column to flip 180 'through magnetic coupling. When the liquid level rises, the turnover column changes from white to red, and when it falls, the turnover column changes from red to white, so as to realize the indication of the liquid level.
2. The upper and lower limit switch output uses the magnetic float to move with the liquid level to make the switch installed on the set position of the liquid level gauge riser act to realize on-off control or alarm. Magnetic flap liquid level gauge is widely used for liquid level measurement and control in the production process of electric power, petroleum, chemical industry, metallurgy, environmental protection, shipbuilding, construction, food and other industries.
