Automation Is Our World. A Perfect Application Solution Is  A willingness to take entrepreneurial risks, a pioneering spirit, and a firm belief in their own inventive powers – these were the assets that Walter Pepperl and Ludwig Fuchs started out with when they opened their Mannheim radio repair shop in 1945. Their invention of the proximity switch a few years later proved their strength. It was also the starting point in a successful history defined by close customer relationships as well as innovative automation technologies and procedures. Then as now, our focus is directed squarely on...

Measuring Methods Limit Level or Continuous. Two Measuring Methods, a Host Whether you need continuous measurement data on the fill level or you want to monitor a medium with limit level measurement, it is clearly a question of method. Pepperl+Fuchs supports you by offering measurement technology that is tailored specifically to your needs. Reliable Monitoring: Limit Level Measurement Limit level measurement is used to ensure that monitored media neither exceed nor fall below a specified level. This form of measurement can prevent overfill in containers or pumps from running dry. The...

Vibration level measurement is a proven method for recording the limit level in liquids and bulk goods. A tuning-fork sensor oscillates by means of a piezoelectric charge. When the sensor comes into contact with the product as it rises, the frequency of the oscillations changes. The evaluation electronics then convert this change into a switching signal. Capacitive limit switches provide a simple method for limit level detection in light bulk goods. A rod or cable probe forms a capacitor together with the tank wall. As the quantity of product changes, so too does the capacity of the...

Measuring Principles Choosing the Right Technology for Pressure, vibration, ultrasound, float – the range of measuring methods is extensive. Choosing the right technology depends entirely on your specific requirements: Are you monitoring bulk goods or liquids? Do you have abrasive or corrosive media? The range of products available from Pepperl+Fuchs provides the perfect method for all measurement tasks. This method is suitable for recording limit levels in all conductive fluids. To record the limit level, electrodes are arranged at a specified fill limit. If the contents of a vessel reach...

Your Measurement Application. Guided Float Hydrostatic Pressure Measurement This method can be used for recording trip values as well as for providing continuous measurement. A magnetic float is guided by a sliding tube. If the built-in magnet rises or falls, it activates reed contacts integrated into the probe tube. Hydrostatic pressure measurement is a proven method of contin­ uously determining the fill level of a product. This approach takes advantage of the fact that pressure in a liquid rises con­ stantly as the fill level increases. A stainless steel membrane transfers the pressure...

Guided Microwave Ultrasound is a contactless method of providing continuous level measurement. With this method, a measurement is taken of the time that elapses between an ultrasonic pulse being emitted and the echo reflected by the product surface being received. The run time can then be used to calculate the exact distance between the emitter and the surface to determine the fill level. This method is based on the principle of measuring the run time of microwave pulses in liquids and bulk goods. This is accomplished by feeding a direct-current pulse through a probe rod or cable and...
