Intelligent Tank Sensor ITS 60 for Diesel Fuels

BEDIA intelligent tank sensor ITS 65 is used to monitor the filling levels of oils of any kind. The sensor is able to automatically recognize and what kind of oil (hydaulic oil, engine oil etc.) is present and calibrates itself to it. The capacitative measurement principle permits measurement of levels without mechanically moving parts. This considerably increases stability and operating safety. Mechanics The new tank sensor ITS 65 is characterized by a particularly stable, but light mechanical system specially designed for “Heavy Duty Applications”. The mounting flange and measurement tube are constructed from die cast aluminium. This construction permits the insertion of tank sensors up to 1200 mm in length, without additional support on the tank floor. Analogue Output The analogue output is available as an voltage output with a range from 0 V to 10 V or as an PWM output.

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.

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.
