1. Application filed

CS03 series integrated car is special oil level sensor, oil tank, oil tank truck, oil depot for railway locomotive and vehicle such as the precise measurement of the oil level and tailored special instrument, USES the advanced capacitance sensor acquisition circuit of signal processing with 16 bit single chip microcomputer, the accuracy can reach 0.2%. The machine there or flexible components, impact resistance, easy installation, high reliability, high precision and good cost performance. Can be installed in various occasions for gasoline, diesel oil, hydraulic oil and oil level accurate measurement and control

2. Feature

1) simple structure, moving or elastic components, so the reliability is extremely high, little maintenance. In general, don't need to repair.

2) accurate temperature compensation to eliminate the error caused by heat bilges cold shrink oil medium.

3) can be used in high temperature oil level measurement, and the measured value is not affected by the temperature of the liquid to be tested, proportion, and the shape of the container, pressure influence.

4) the output signal of damping time, eliminates the data fluctuation caused by vibration and turbulence.

5) perfect over-current, over-voltage, power supply polarity protection

3.working principle

CS03 series integrated automotive special sensing part of the oil level sensor is a coaxial container, after the oil into a container to cause the change of the sensor shell and sensor capacitance between electrodes, the change amount by the transformation of the circuit and precise linear and temperature compensation, 4 ~ 20 ma output supply standard signal display instrument

4.Technical data

1)Detection range: 10-2000 ㎜

2)Low accuracy: 0.5 magnitude 0.5 on the Richter scale are unlikely

3)Range of low pressure: 0.1 MPa ~ 5 MPa

4)Low ground very heat-resistant: - 50 ~ 120 ℃

5)Low temperature: - 20 ~ 70 ℃

6)Low output signal: 4 ~ 20 ma

7)Low power supply: DC12 ~ 28 v (24 VDC) typical values

8)Low fixed way: thread M16 x 1 installation

5.installation and commission

1) sensor for the standard two wire meter, power supply (signal lines should use the shielded wire or two new together of twisted pair, as far as possible don't with other wires through the line pipe or open wire slot, nor through the near high power equipment.

2) this product in the factory has a calibration, can be suitable for most of the non-conductive liquids. If need on-site adjustment can adopt the following methods:

The zero -when the oil level in the lower limit, the white line and black line short answer it, automatically adjust the output current to 4 ma. Field adjustable full - when the oil level in the ceiling, the yellow line and black line short answer it, automatically adjust to 20 ma output current. After adjust, should be white and yellow wire with waterproof tape wrapped up.
