Nony, share the pneumatic valve static characteristics of the indicators

static characteristics is refers to the pneumatic valve stroke and the static relationship between the input signal, so also known as static characteristics. Here are all kinds of static characteristics of the basic definition of the indicators.

and basic error within a specified reference conditions, the characteristic curve of actual itinerary and rules of characteristic curve, the biggest difference between called basic error.

the rise and fall, back to the same input signal of the biggest difference between the two corresponding travel value

and linearity error of calibration curve and the appropriate line ( Independent line, zero-base straight, the base line) The maximum deviation between the linearity error. Within the scope of the input signal, the rise and fall of the two directions of to determine the two or more times, in all of the input signal measuring point, the average of the data, using the point out the biggest difference between the average curve and linear is linearity error.

deviation deviation, also known as starting point, beginning, end point zero point error and deviation, also known as the finish end point error. Instrument under the specified conditions of use at work, when the input signal is the scope of the upper and lower limit, adjust the corresponding trip of pneumatic valve value error referred to as the starting and end point of deviation. The beginning and end point deviation with regulating pneumatic valve rated stroke expressed as percentage.

, rated travel deviation meter work under specified conditions of use, e. when input more than the upper limit value of the signal range of error, referred to as the nominal schedule deviation.

and repetitive work in the same condition, on the same input values in the same direction between the continuous measurement of the output on duty the consistent degree of repeatability. Repeat performance said instrument instrument the size of the random error. Adjust the repeatability of pneumatic valve is with full range of the input values are measured to determine the maximum repeatability error. Repeatability does not include the return difference and hysteresis.

and reproducibility of the same work conditions and time, on the same input values from the two opposite direction on a speech between output value of the repeated measurement program degree is known as the reproducibility. Reproducibility including dead zone and hysteresis, drift and repeatability. Reproducibility by the full range of the same input values of repeated measurements accordingly and falling on the biggest difference between the output on duty of, and expressed as a percentage of range.

and dead-zone input signal positive and negative direction change does not cause stroke type can detect any change of limited range.
