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.

The TLS 100 tube sensor works on the capacitive measuring principle and detects the presence of a liquid in a plastic tube. These plastic tubes may also be mounted as a by-pass on a compensator in order to signal the required medium level in containers. The sensor is simply snapped onto the tube at the ideal level of the medium and provides versatile usage for a wide range of applications in medical equipment, the food stuffs industry etc. The sensor can additionally be fixed by means of the two mounting lugs to ensure a tight fit on the tube. Caution The switch point is factory pre-set so as to lie exactly between the two mounting clips. When readjusting the switch point, please observe that it again lies between the two clips. A mass surface in the proximity (< 10 mm) may influence the switch point and may necessitate a readjustment.

BEDIA intelligent tank sensor ITS 60 is used to monitor the filling levels of Diesel fuels. The sensor is able to automatically recognize what kind of Diesel fuel (Bio-Diesel, Summer-/Winter-Diesel etc.) is present and calibrates itself to it.
