Level measurement devices from SICK MAIHAK AG

Devices for level measurement are part of MBA Instruments’ core business. In addition to reliable rotating paddle technology, our product range comprises membrane switches as well as level measurement devices with radar sensors, vibrating or semi rotating paddles and continuous measurements. Our product portfolio is constantly supplemented by new and further developments because even proven devices benefit from innovations: in this list you will find either the link to the optimized original successor of a discontinued product or the reference to our product configurator. This makes it easy for you to find the most suitable model for your purposes.

MBA808

Level measurement with cone smoothing

The “2-in-1” model of the MBA800 electronic paddle series offers two functions combined in one device. With steady filling, it levels the bulk cone with its own force and then emits a signal when the silo is full. This results in the optimum utilization of the silo capacity. Like all MBA800 series devices, the MBA808 is also based on stepper motor technology. This device makes full use of the possibilities of stepper motor technology. While a very large paddle uniformly levels the bulk material with great force during filling and pushes it circularly toward the inner wall of the silo, the previously unused flanks of the bulk cone are also filled. The MBA808 emits an additional "Silo completely full" signal only when it is no longer possible for a bulk cone to form and the silo is completely full. Like all devices of the MBA800 series, the MBA808 is based on stepper motor technology.

MBA400

Continuous radar level indicator

The MBA400 uses radar measuring to guarantee precise and reliable filling level measurements even in narrow silos or silos with additional installations. The level measurement is carried out without physical contact between the measuring device and the bulk material. A transmitter emits radar pulses, which are reflected by the bulk material. The time measured is proportional to the filling level. The radar filling level indicator can be used in silos of up to 75 meters. Typical areas of application are the food industry, chemical and construction industry, as well as plastics processing and steel manufacture.

MBA369

PERPENDICULAR FOR CONTINUOUS MEASUREMENTS

With the MBA369 perpendicular, the level can be measured in all types of bulk materials. Only a perpendicular like this can determine the height of sediments below the surface of water or liquids by means of a sieve weight. It is also suitable for the continuous level measurement of liquids.

MBA2.2/3.2

“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.

MBA300

Continuous level measurement with radar technology

The MBA300 uses radar pulses, which are reflected by the bulk material, to continuously measure filling levels. This method is used primarily in the food and construction industry, as well as plastics processing and steel manufacturing. By using radar technology this type of level measurement guarantees that there is no physical contact between the measuring device and the bulk material. The radar filling level indicator can be used in silos, bunkers and many other containers of up to 15 meters.

Strong, safe and reliable – rotating paddle devices of the MAIHAK type have been proven for over 70 years. The filling level indicator signals full/demand/empty bulk material in large storage silos, as well as in small containers. In downspouts and conveyors it promptly signals backlog in the product flow. It has an alternating voltage motor: if the blade is stopped the motor automatically switches off, therefore consumes no energy and is not loaded during standstill. The level switch measures various fill materials such as granulates, feed, spices or powder.

Level indicators of the MBA series are robust electromechanical sensors which detect the presence of bulk material at the place of installation. They are designed to monitor the filling of a bulk material container. Their possible applications depend on the design of the individual device. Variable are for  example:

  • Shape and size of the device (= type of device)
  • Size, shape and material of the rotating paddle
  • Material and design of the rotating shaft
  • Seal between the housing and the rotating shaft
  • Safety standard (e.g. explosion protection)
  • Permissible operating temperature

To MBA800

 

An MBA level indicator consists of an indicator head and an extension arm. The head contains the electrical and electromechanical components and is attached to the outer wall of the bulk material container. The extension arm protrudes into the bulk material container. It consists of a shaft with a paddle and, depending on the type, a protective tube and support bearings for the shaft. The electric motor in the indicator head slowly rotates the shaft and the paddle. When the bulk material surrounds the paddle, it blocks its rotational motion. The resulting counter torque is used to turn the motor mechanics against a switch, which then shuts the motor off. The switch has a second (dry) contact for the status signal.
