根据IEC60770, 20 (68 ) 的环境温度，65%的相对湿度,1013hPa的大气压( 1013mbar)，安全位置为垂直膜片，零基量程，变送器采用隔离膜片，AISI316Lss或哈 氏合金和硅油填充或ABB填充，使用HART数字净值( 等于4-20mA的量程端点) ,线性模式。.除非另有说明，误差按量程的百分比%标示。某些性能数据受实际量程比(TD)即测量上限和标定量程的比值的影响。建议选择量程比低的变送器传感器代码，以使性能指标达到优化。

performance index


According to iec60770, 20 (68) ambient temperature, 65% relative humidity, 1013hpa atmospheric pressure (1013mbar), the safe position is vertical diaphragm, zero based range, the transmitter is filled with isolation diaphragm, aisi316ls or Hastelloy and silicone oil or abb, Hart digital net value (equal to the range end point of 4-20mA) and linear mode Unless otherwise specified, the error is indicated as a percentage of the range. Some performance data are affected by the actual range ratio (TD), that is, the ratio of the upper measurement limit to the calibrated range. It is recommended to select the transmitter sensor code with low range ratio to optimize the performance index.
