YLE Crankshaft Positioning Sensor measuring instruments can only provide light

Single beam and single wavelength measurements, as the name suggests, this CO2 YLE Crank Position Sensors measuring instruments can only provide a single wavelength of light. It's the worst performance in the 3 kinds of measurement methods, the stability is affected easily by such as lamp aging, dust pollution and light emission characteristics change and other factors. At present in the market for the sale of many kinds of single beam single wave length measuring instrument, stability is not very ideal in addition, temperature changes will affect their stability. But the advantages of this instrument is simple mechanical structure reliable and cheap. YLE Coolant Temperature SensorDouble beam dual wavelength measurement, the combustible gas detection instrument with 2 light Du channel, 1 probe and 2 filter, compared with an instrument, its accuracy and stability are improved, but the corresponding the price is higher. In addition to improve its operating temperature range, 2 detectors must match exactly. In practical application, dust 2 wave channel by pollution will also give this kind of measuring instrument for non symmetric pollution and accuracy of misalignment problem
