MBA combines robust and reliable mechanics with state-of-the-art electronics in the production of level indicators for bulk goods and liquids. The main advantage of the MBA200 rotary blade indicator is that it can be used to indicate full and empty statuses for nearly all bulk goods. Notification is given in a safety-oriented manner: This way, the level indicator prevents a silo from overflowing, even if malfunctions such as a power outage or broken wire in the supply line occur. The device has a large clamping space which facilitates simple and secure cable connection and has a device head which can be rotated easily to enable precise adjustment after assembly. The switching sensitivity can be set with ease. With models designed specially for areas prone to explosion, temperatures of up to +800 °C and high pressure and available with a diverse array of rigid and flexible shafts, the MBA200 is well-suited for any bulk good.
