Product description

The main parameters of the static characteristics of the pump Pressure Sensor are linearity, sensitivity, hysteresis, repeatability, drift, etc. (1) Linearity: refers to the degree to which the actual relation curve of the output and input of the Water Pressure Sensor deviates from the fitting line, which is defined as the ratio between the larger deviation value of the actual characteristic curve and the fitting line in the full range and the output value of the full range. (2) Sensitivity: An important indicator of the static characteristics of the water pressure sensor is sensitivity, which is defined as the ratio of output increment to the corresponding input increment causing the increment. The sensitivity is denoted by S. (3) Hysteresis: the Water Pump Pressure Sensor input from small to large (positive stroke), input from large to small (negative stroke) into hysteresis, the sensor input and output characteristic curve does not coincide, resulting in the pump pressure sensor output signal size of positive and negative stroke is not equal, for the same size of the input signal, the difference is called hysteresis.   (4) Repeatability: After the input of the water pressure sensor is continuously changed in the full range in the same direction for many times, the degree of inconsistency of the obtained characteristic curve refers to the repeatability of the sensor. (5) Drift: the drift of the water pressure sensor refers to the change of the output of the sensor with time, in the case of constant input, this phenomenon is called drift.
