Static characteristic refers to the dynamic connection between valve path and output signal, also known as dynamic characteristic. The above is the basic definition of the static characteristics of various ethnic groups. 1. Fundamental error In a regular reference environment, the maximum difference between the characteristic straight line of the actual route and the characteristic straight line of the regular route is called the fundamental error.

2. The starting point and the starting point are biased towards the starting point.  wholesale Brass Faucet Valve  The bias is also called the two-point error, and the bias at the starting point is also called the starting point error. When the measuring tool is working in a regular operating environment, when the output is the upper and upper limit values ​​of the signal range, the error of the response path value of the adjustment valve is called the deviation of the starting point and the starting point. The starting and starting point deviations use the percentage of the extra distance of the adjustment valve to indicate the extra distance deviation. When the measuring tool is working in a regular operating environment, the error when the output exceeds the lower limit value of the signal range is called the extra distance deviation.

3. Hysteresis is the maximum difference between the two echo distance values ​​of the same output signal falling and falling. 4. The forward and reverse position changes of the dead zone output signal will not cause any perceptible change in the infinite interval (Figure " # ").

5. Repeatability In the same working environment, the difference between the input values ​​measured repeatedly at the same position for the same output value is called repeatability. The repeat function indicates the size of the random error of the gage. The repeatability of the regulating valve is determined by the maximum repeatability error measured by each output value in the whole range. Repeatability does not include hysteresis and hysteresis.

6. Reproducibility In the opposite working environment and regular time, the level of divergence between input values ​​measured repeatedly from two identical positions for the same output value is called reproducibility. Reproducibility includes deadband, hysteresis, drift and repeatability. Reproducibility is determined by the maximum difference between the corresponding drop and drop input values ​​measured repeatedly for the same output value over the entire range, and is expressed as a percentage of the range. 7. Linearity error The maximum deviation between the calibration straight line and the appropriate curve (Golden Rooster independent curve, zero-base curve, end-base curve) is the linearity error. In the entire output signal range, for the two positions of falling and falling, the default setting is performed twice, and at the default point of each output signal, the average value of each data is obtained, and the average line and curve drawn by the point are used. The largest difference between them is the linearity error.
