Product Details

German Mollet MFE-A Diaphragm Level Switch Metal Diaphragm Level Switch

summary:The MOLLET membrane switch from Germany can be used for full tank, empty tank, or required level switch positions according to the requirements of the working conditions. The MJ series membrane switches can be installed on various containers such as inspection silos, containers, and discharge pipelines. They can be used to detect blockages in pipelines: screw conveyor blockages, pipelines, and provide indications during input and output. MJ membrane switches have * * reliability and safety functions, even under extreme conditions.

Saving and utilizing resources is one of the biggest challenges facing global industry. Currently and in the future, there will be increasing discussions on topics such as improving production efficiency, reducing electricity consumption, lowering energy management costs, strengthening energy management, optimizing energy structure, and improving and strengthening cost control. The focus of industry discussions is to provide high-tech solutions. An often overlooked point is that low tech instruments can also make significant contributions to improving energy efficiency.

Level switch without power supply:
In the field of level measurement technology, various measurement techniques can be used, including radar level gauges, ultrasonic level gauges, and tuning fork level gauges. Almost all level gauges need to provide energy to sensors 24/7 to ensure their normal operation. MOLLET membrane level gauge is different, it is a sensor that can reliably display the level of solid materials without any operating energy. Media visualization, process automation. Its application range is very wide, not only can it reliably detect powders in the food industry, but it can also reliably detect the level of coarse gravel or plastic particles in the building materials industry.

Technical advantages:
MOLLET membrane level switch has many advantages compared to other level measuring instruments. Because there is no need for power supply, it saves energy and eliminates the need for laying power lines. The installation and debugging of sensors are very simple - no calibration or calibration is required. The membrane can be installed flat on the outer wall of the silo, without any instrument components protruding into the silo or container. This maintenance free sensor is particularly suitable for measuring full, empty, or demand indicators. It can be used to prevent overflow of the material level, or to maintain the set material level and display blockage information for ramps, conveyors, or lifting machinery.

Meeting customer needs:
Many customers' desire is to save energy. They do not want to save energy through innovative sensors, but more importantly, they hope to save energy through level instruments that can perform reliable and economical level monitoring without running energy. The membrane level gauge produced by MOLLET GmbH in Germany precisely meets this requirement and has been widely used in the fields of solid material storage, transportation, and processing worldwide.

MOLLET Germany:
Wolfgang Hageleit founded MOLLET in 1983, and guided by its business philosophy, the company has now developed into a global supplier of safety equipment for silos. The company is located in the local industrial park in Osterburken, where staff design and develop all products and systems, implement mass production, installation, final inspection, and shipping. The company's innovative products also include built-in limit switches for hose joints, high and low pressure protection control valves for silos, overfilling monitoring systems for silos and storage tanks, and anti rotation level gauges.

MOLLET's MF series diaphragm level switch is a single point control switch that can be used to measure solid materials with bulk densities ranging from 0.3 t/m ³ to 2.5 t/m ³. When the material in the warehouse comes into contact with the sensor, the pressure exerted by the material on the diaphragm will cause the switch to operate. Activate the micro switch through a lever mechanism and output an electronic signal of up to 4A at 250V AC. When the material leaves the sensor, the pressure acting on the diaphragm disappears, and the diaphragm will return to its original state by the elastic force of the spring, and the micro switch will actuate again. The gravity of the materials in the warehouse and the elastic force of the spring can provide the required switch action energy - without any other form of auxiliary energy. By utilizing the gravity of bulk cargo, when the material (cargo) touches the membrane, it causes compression of the membrane. The signal switch will be generated and released through this compression.

Material level switch selection:
All components in contact with the product, such as fixed rings and diaphragms, are made of special steel. If you don't need to use these materials, you can order lower priced materials such as Viton film or galvanized steel fixing rings.
The shell is available in two materials: cast aluminum and plastic. Depending on the structure of the measuring instrument, the operating temperature range is -30 ℃ to+200 ℃, and it can measure bulk materials with particle sizes up to 100mm in the warehouse. In addition, this level instrument has obtained permission for use in areas with gas and dust explosion hazards.

Suitable for mixtures

The MF membrane level gauge can be installed in any environmental location, including dust, particulate matter, and granular materials, and is suitable for almost all industrial fields.

Application Example - Material Blockage Monitoring:
In the production process of mixed feed, raw materials, intermediate products, and final products are transported multiple times between different processes. Materials are often transported using conveying equipment such as screw conveyors. Especially, it is necessary to avoid the danger and waste caused by material blockage at positions where materials are transported within a short distance of 20 meters and thoroughly mixed. In order to monitor the flow of materials, MOLLET has specially designed and developed a membrane level gauge that can be installed at the discharge end of a screw conveyor. When the material is blocked, the screw stops running and outputs a fault signal. When the maintenance personnel identify the cause of material blockage and manually operate the switch of the diaphragm with the reset button, the fault signal will return to its original state. This can be achieved by installing a dedicated switch with two switch positions.
