Sensor static characteristic parameters indicators ⒈ Sensitivity Sensitivity refers to incremental and steady state input sensor output y and input ratio x car level sensor manufacturers, or the output of the x-y incremental ratio, by k The minimum amount of change is measured as k = dY / dX⒉ resolution of the sensor in a predetermined measurement range can be detected is called the resolution. ⒊ measurement range and span within tolerance limits in automotive wholesale level sensor is the lower limit of the range between the upper limit of the measuring range of measured values ??is called. ⒋ linearity (nonlinear error) under specified conditions, the sensor calibration curve fitting with the largest percentage deviation from a straight line between full-scale output value is called the linearity or non-linear error. ⒌ Hysteresis Hysteresis refers to the extent inconsistent with the working conditions at the same level of quality automotive sensors, positive stroke characteristics and anti-stroke characteristic of the sensor. ⒍ Repeatability Repeatability is under the same operating conditions, the input in the same direction over the entire measuring range continuously variable characteristic curve obtained several inconsistencies. ⒎ zero drift and drift sensor when there is no input or another value, at regular intervals car level sensor input value deviates from the percentage of full scale of the maximum deviation from the original indication zero drift. The temperature is increased by 1 ℃, the percentage of the maximum deviation of full scale sensor output value, known as drift. Commonly used types of sensors on the car including the wheel speed sensor, crankshaft / camshaft position sensors, temperature sensors, pressure sensors, knock sensors. For the endless stream of models, each feature the same sensor in shape and have a variety of differences, coupled with the measure, the production environment become more demanding, the traditional single test bench not take into account such diverse sensor production.
