国内外气动或电动单元组合仪表刻度的换算,可以用图表法,也可以用公式法。目前仪表的标准刻度基本有两种,一种是线性刻度,如压力、温度、液面测量等;另一种是方根刻度,如:差压式、靶式流量测量等。单元组合仪表刻度即仪表信号值和参数值之间的换算通用公式见下表。 Domestic and foreign pneumatic or electric unit instrument scale conversion, you can use the chart method, you can also use the formula method. At present, there are basically two standard scales on the instrument, one is a linear scale, such as pressure, temperature, liquid level measurement; the other is a square root scale, such as: differential pressure, target flow measurement. Unit combination meter scale that the instrument signal value and the conversion between the values ​​of the common formula in the table below.
