Precision Precision is an important performance indicator sensor, which is related to the entire measurement system is an important part of precision. The higher precision of the sensor, the more expensive the price, and therefore, the accuracy of the sensor as long as meet the accuracy requirements of the entire measurement system can be, a temperature sensor, do not have to choose too high. So you can choose relatively cheap and simple sensors Atlas air compressor parts meet the same measurement purposes in many sensors. If the aim is to measure the qualitative analysis, the choice of high repeatability of the sensor to the sensor works, should not use the absolute value of high precision; If it is for quantitative analysis, you must obtain accurate measurements, Yuncheng sensor, on the need to use precision levels to meet the requirements of the sensor. For some special occasions, you can not choose the right sensor, we need to design and manufacture sensors. Homemade sensor performance should meet the requirements. Capacitive level sensor consists of a capacitive sensor and an electronic module circuit, it is a two-wire 4 ~ 20mA constant current output as the base type, after conversion, you can use three-wire or four-wire output, the output signal is formed as 1 ~ 5V, 0 ~ 5V, 0 ~ 10mA and other standard signals. Capacitive sensor consists of insulated electrode and the cylindrical metal container filled with the measuring medium components. When the material level rises because the dielectric constant of the non-conductive material is significantly less than the dielectric constant of air, so the capacitance change with altitude change material. Module circuit sensor by the reference source, pulse width modulation, conversion, constant current amplification, feedback and current limiting unit. The advantage of using the principle of pulse width modulation special measure is to lower frequencies, radio frequency interference on the surrounding elements, good stability, good linearity, no significant temperature drift.
