capacitive sensors - KB120120

BEDIA level monitoring sensors are used to monitor the filling levels of liquids. The sensors detect when a filling level is exceeded or falls below a limit. Water-based liquids like coolants, AdBlue®, fresh water, waste water, bilge water and oil-based liquids like motor oils, hydraulic oils, fuels and brake fluids can be monitored. Since they contain no mechanical moving parts, their function will not be influenced by dirt particles or other influences. No electrical current is sent through the medium via an electrode with BEDIA sensors, an electrolysis of the medium is not possible. Operating Principle The function of the sensor is based on the capacitive principle. It detects the change in capacitance that occurs when an electrode surrounded by air is immersed into a liquid medium. This change in capacitance at the electrode of the sensor excites an oscillator. This signal is processed by a microcontroller-based evaluation circuit which activates or deactivates an output stage.

EGE capacitive level sensors for adhesive media offer the reliable monitoring of the filling level of granulate, powders, solids, such as feathers, fluids and aggressive as well as adhesive media. The medium to be detected functions as dielectric. The medium in touch with the sensor generates a capacity change. This is converted into a switching signal or an analogue 4...20 mA output signal. Level sensors of series KGFR are ideal for media with low DK value. The PTFE sleeve makes the sensor resistant to aggressive media and together with the round design ensures the fast slippage of the medium.
