RF3100 for Latex Foam level detection
The latex liquid is very sticky and the customer used different types of level switches. All had problems with heavy coating and had malfunctions. The probes could not detect reliable and needed to be cleaned monthly.
The capacitance sensor RF3100 can be adjusted idealy to the right switch point, also the probe is covered with the sticky latex product. The sensitivity is setted to 10pF, because the DK value is quite high and the capacitance change between uncovered and covered probe is also in a safe range. The active shield guarantees the sensor to perform perfectly regardless of heavy coating. The ideal sensor for this application.
