Capacitive sensors play a crucial role in monitoring the fill levels of liquids and various media. Their technological advantages enable them to detect fill levels through plastic or glass walls without direct contact with the media. This capability proves particularly beneficial for handling aggressive liquids, food substances, or laboratory fluids stored in closed containers, where contact with foreign particles is to be avoided. While conventional capacitive sensors have limitations when microfilms or residues adhere to the inside tank walls as the fill level decreases, the PL240 capacitive sensor from Baumer overcomes these challenges. This new sensor, employing an intelligent measuring principle, ensures reliable point level detection even under these adverse conditions, making it a standout solution in fluid monitoring.
The PL240 sensor is specifically designed for applications involving film-forming media. It can operate seamlessly even when films or residues adhere to the tank walls, a scenario where traditional capacitive sensors may falter. This capacitive sensor can discern whether the detected substance is the actual medium or just a residue film, eliminating the risk of machinery running dry. Additionally, it exhibits high resilience to external influences, making it less sensitive to minor touches on the tank that could result in switching errors. The PL240 capacitive sensor can function effectively even with wall thicknesses of up to 6 mm. When attached externally to plastic or glass containers, it reliably detects point levels of water-based media, such as cleaning fluids, milk, or laboratory liquids, thanks to its ability to compensate for adherence. Moisture and wetness, as well as incidental touches on the tank, do not interfere with the sensor’s performance.
One of the standout features of the PL240 sensor is its quick and easy installation directly onto tanks or tubes using adhesive tape, cable ties, or screws. Its high performance allows for air gaps of up to 1 mm between the tank and sensor, offering flexibility in installation. This feature is particularly beneficial when dealing with swap containers, where direct container contact may be absent or challenging to establish. The PL240 capacitive sensor is virtually ready for use in most applications and does not require elaborate teaching operations. Its versatility makes it suitable for a range of applications, including lab automation, equipment engineering, and semiconductor production. By introducing the PL240 point level switch, Baumer extends its comprehensive toolbox for smart fluid monitoring, providing users with an additional user-friendly and efficient solution.
