Whether it's continuous fill level measurement, high/low position detection or both combined: Balluff offers a wide range of solutions for process control storage. Depending on the installation situation, media properties and environmental conditions, we offer reliable sensors that only have one goal: Efficient processes.
You can choose between contact-free or with contact. Balluff sensor technology can also be used to measure the fill levels of liquid paste-like media or granular media through plastic tank walls.
Balluff capacitive sensors reliably detect the fill levels of almost all materials from outside of the container. These sensors are wear-free and work without coming in contact with the actual material.
Where fill level measurement is critical for processing or fillng operations, Balluff offers several options for continuous fill level monitoring including ultrasonic sensers, sanitary linear transducers that can be immersed in the liquids and even pressure monioting sensors. Depending on the application need, contact-less or contact based solution can be employed.
Balluff ultrasonic sensors enable stand-off monitoring of bulk material levels on conveyor belts and in silos. Using reflected sound waves to detect material height from a distance, ultrasonic sensors can reliably monitor materials having a variety of colors and textures…even under the harsh operating conditions found in a steel mill. Ultrasonic sensors help ensure that blast furnaces are reliably charged, even in the presence of dust and dirt caused by ore charges and coke.
Applications to verify proper liquid level in the pipette tip or the dispensing of liquid or that the tip is in the correct position requires a narrow focused light beam in a small housing. Balluff's micro-optic MICROmote photoelectric sensors can easily solve these critical applications. With sensing heads as small as 2mm and "wired fibers" with no minimum bending radius these miniature sensors can easily fit in the smallest of spaces. The remote amplifiers have multiple teach options that can solve the most difficult applications and a variety of outputs that makes integration into control systems quick and easy.
Two levels of blood are monitored in heart-lung machines to indicate when blood drops below the minimum level. Balluff's hybrid capacitive technology can accurately detect the difference in the actual blood level and any blood that inherently adheres to the wall of the reservoir. The sensors are typically adhesively mounted to the blood reservoir at the desired level enabling them to be reused.
Dry granulate is essential for high-quality plastic parts. Our capacitive stainless steel sensors resistant to high temperatures ensure an even feed of the moist granulate into the dryer. They are heat resistant to 250 °C and reliably monitor all levels.
The beverage industry uses stretch blow molding machines to produce bottles. If the bottles are filled immediately afterward, our high-precision SF fill level sensor controls the fill level during the process. On-site filling can save you transport distances and thereby minimize costs.
Balluff capacitive sensors detect fill levels of acids, bases or deionized water without contact through sight-glasses. Balluff's hybrid capacitive technology compensates for moisture, and foaming. Block style sensors can be installed quickly and easily with cable ties or sight-glass mounts are available for tubular style sensors.
In the semiconductor industry level detection in direct contact with media is not a preferred method. However in waste tank level applications direct contact is not an issue. Balluff offers the widest variety of capacitive sensors and mounting methods in the market. Complete Teflon (PTFE) sensors with Teflon switch wells would be the ideal solution for this application. Balluff's hybrid capacitive technology offers the most reliable solution as it would ignore the filming and material build up on the sensor and switch well.
Optimum fill levels should always be maintained in the expansion tanks gearboxes, hydraulic systems, and cooling systems. Balluff's capacitive level sensors detect the maximum and minimum fill levels without direct contact to the media, either through the container wall or with the help of mounting adapters. They can also be installed in the oil pan as a leak sensor and will reliably report the presence of oil where it shouldn't be.
