、 范围range 3 , range
An interval of a quantity defined by upper and lower limits.
Note: " Scope " is usually modified. For example: measurement range, scale range. It can be applied to the measured or working conditions.
、 测量范围measuring range 4.Measuring range
The range to be measured in accordance with the specified accuracy (precise) accuracy.
、 测量范围下限值measuring range lower limit 5.Measuring range lower limit
The minimum value to be measured with the specified accuracy (precise) accuracy.
、 测量范围上限值measuring range higher limit 6.Measuring range higher limit
The measured maximum value that is measured according to the specified accuracy (precise) accuracy.
、 量程span 7 , span
The algebraic difference between the upper and lower limits of the range. For example: when the range is -20 ℃ to 100 ℃ , the range is 120 ℃ .
、 标度scale 8 , scale
An ordered set of scale marks and all relevant numbers forming part of the indicating device.
、 标度范围scale range 9 , scale range
The range bounded by the start and end values of the scale.
、 标度标记scale mark 10 , scale mark
A scale line or other mark on the indicating device corresponding to one or more determined measured values.
Note: For digital indication, the number itself is equivalent to the scale mark.
、 零[ 标度 ] 标记 zero scale mark 11 , zero [ scale ] mark zero scale mark
Synonym: zero-scale line.
A scale mark or scale line marked with a " zero " number on the dial (plate) .
、 标度分格scale division 12 , scale division
The portion of the scale between any two adjacent scale marks.
、 标度分格值value of scale division 13 , value of scale division
Also called grid value.
The difference between the measured values corresponding to two adjacent scale marks in the scale.
、 标度分格间距scale spacing, length of a scale division 14.Scale spacing, length of a scale division
The distance between the centerlines of any two adjacent scale marks measured along the same line segment representing the length of the scale.
、 标度长度scale length 15 , scale length
On a given scale, the length of the line segment that passes through the midpoint of all the shortest marks between the beginning and end scale marks.
Note: This line segment can be a real or imaginary curve or straight line.
、 标度始点值minimum scale value 16.Minimum scale value
The measured value corresponding to the start mark of the scale.
、 标度终点值maximum scale value 17 , maximum scale value
The measured value corresponding to the end point of the scale.
、 标度数字scale numbering 18.scale numbering
The entire set of numbers marked on the scale, which correspond to the measured value determined by the scale mark, or only represent the numerical sequence of the scale mark.
、 线性标度linear scale 19 , linear scale
A scale in which the spacing between the cells in the scale has a constant proportional relationship with the corresponding cell value.
Note: A linear scale with a constant grid spacing is called a regular scale.
、 非线性标度nonlinear scale 20.Nonlinear scale
The scale in each scale has a non-constant proportional relationship with the corresponding grid value.
Note: Some non-linear scales have special names, such as logarithmic scale, square law scale.
、 抑零标度suppressed-zero scale 21.Suppressed-zero scale
The scale does not include the scale corresponding to the measured zero value. Example: Medical thermometer scale.
、 扩展标度expanded scale 22.Expanded scale
。 Within the scale range, the disproportionate extended portion occupies most of the scale length scale .
The meter series sold by Jiangsu Dongxiang Meter are: flow meter temperature meter pressure meter calibration meter level meter digital display meter transmitter meter etc.
