The capacitive level sensor BEDIA NR 150 is suitable for liquids with low relative dielectric constant εr 1,8 … 6 (ref. εr 2,1). It has a MIN/MAX selector switch and the functions for MIN or MAX monitoring as well as other properties (output signal LSS or HSS, response delay etc.) are factory pre-set. The switch point is adjustable by means of a teach-in momentary switch.

BEDIA level monitoring sensors are used to monitor the filling levels of liquids. The sensors react when a filling level is exceeded or falls below a limit. Aqueous mediums 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 arises 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, causing it to oscillate. Then this signal is processed by a microprocessor-based evaluation circuit.

Areas of Application and Advantages BEDIA CLS 10 stands for special versions of our well-proven CLS 40 series for heavy duty applications. Currently, the BEDIA CLS 10 series includes a variety of sensors, which are compatible replacement parts for level switches from Cooper Standard and Robert Shaw which are obsolete nowadays – and this in well proven BEDIA quality. This also includes sensors with 2 complementary CMOS outputs. It should be emphasized that the water sensors with two complementary outputs can be operated with a supply voltage of 4.75 V DC – 32 V DC. Operating Principle The function of the sensor is based on the capacitive principle. It detects the change in capacitance that arises 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, causing it to oscillate (at a frequency of approx. 600 kHz). Then this signal is processed by a microprocessor-based evaluation circuit.

EGE microwave level sensors monitor the filling level of fluids, powders and granulate with a low DK value and are particularly resistant to adhesion. The MFC sensors are also suited for separation layer detection. The sensitivity is adjustable. The sensors are based on a special variant of microwave frequency shift technology. EGE supplies the sensors in varying lengths up to 1000 mm. The stainless steel and PTFE sensor tip is suited for use in aggressive media.

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.

With the vision systems of the PresencePLUS-series we offer a selection of compact, high-performance image sensors for camera-based inspection and identification tasks. The compact vision sensor iVU closes the gap between the imaging equipment and the sensor level. The iVu sensor can be parametrized directly via an internal touch screen and is thus the solution for many applications, which otherwise would only be very complex to realize by using a large number of normal sensors.
