YLE Camshaft Position Sensor Disadvantages: three parasitic capacitance effect

Initial capacitance capacitive weighing sensor is small, and the lead capacitance, electronic circuit connected with the sensor and the electronic circuit of the stray capacitance and inside the sensor plate and the surrounding conductors capacitors and other so-called YLE Auto Temperature Sensormissing large parasitic capacitance, not only reduces the sensitivity of the sensor, and the capacitance is often random change, will make the instrument work is not stability, influence the accuracy of measurement. So the cable selection, installation, connection method has strict requirements. For example, with good shielding property, its small distributed capacitance of high frequency electric wire as the lead, lead is thick and short, to ensure the instrument stray capacitance is small and stable and so on, otherwise it can not guarantee the high measurement precision.
It should be pointed out that, along with the material, technology, electronic technology, especially the rapid development of technology, the capacitance weighing sensor has been developing and YLE Engine Coolant Level Sensor constantly overcome shortcomings. The capacitance sensor is becoming a high sensitivity, high precision, low pressure sensor in dynamic, and some special measurement has a promising.
