Capacitive fill level sensor for soiled media
Baumer’s new CFAK 12 capacitive fill level sensor detects conductive liquids while suppressing dirt particles and detergent residues.
When detecting fill levels in soiled media, conventional capacitive sensors are susceptible to suspended solids that influence their switching behavior in a negative manner. The new CFAK 12 is the smart remedy for these applications. Incorporated into a grounded metal basin it monitors the fill levels of water and water-based fluids.
Thanks to its special housing design and the plane plastic surface, dirt particles hardly adhere to the sensor. Therefore, the cleaning effort is drastically reduced compared to conventional solutions. Even if dirt should adhere to the sensor the integrated compensating electrode makes sure that it is suppressed and the fill level is still detected precisely. Additionally, the capacitive sensor is extremely resistant to detergents and suppresses their residues reliably.
Amongst others, the capacitive fill level sensor is applied in railway lavatories. On the one hand, it serves as an overfill switch when the lavatory is blocked and the water level rises. On the other hand, by suppressing suspended solids, toilet paper, and detergents it guarantees the successful operation of the flushing system under normal conditions. Besides this particular application, its special features make the sensor applicable for any kind of soiled media level measurements.
