标准摘要
[中文适用范围]: IEC 60770 的本部分适用于具有符合 IEC 60381-1 或 IEC 60382 的标准模拟电流输出信号或标准气动输出模拟信号的变送器。本文详述的测试可适用于具有其他输出的变送器信号,前提是对这种差异给予适当的考虑。有关智能变送器的评估,请参阅 IEC 60770-3。对于传感器作为组成部分的某些类型的变送器,可能需要参考其他特定的 IEC 或 ISO 标准(例如化学分析仪、流量计等)。本标准旨在规定评估传感器的统一测试方法。具有气动或电动输出信号的变送器的性能。本标准规定的评估方法旨在供制造商用来确定其产品的性能,以及供用户或独立测试机构用来验证制造商的性能规格。本标准中定义的测试条件,例如环境温度和电源范围,代表了使用中常见的条件。因此,如果制造商没有指定其他值,则应使用此处指定的值。本标准中规定的测试不一定足以满足专门为异常艰巨或安全相关任务而设计的仪器。相反,一系列受限的测试可能适合设计用于在更有限的条件范围内执行的仪器。当不需要根据本标准进行全面评估时,应进行所需的测试,并根据标准的相关部分报告结果。 [外文原描述]: IEC 60770-1:2010 is intended to specify uniform methods of test for the evaluation of the performance of transmitters with pneumatic or electric output signals. It is applicable to transmitters which have either a standard analogue electric current output signal or a standard pneumatic output analogue signal in accordance with IEC 60381-1 or IEC 60382. The tests detailed herein may be applied to transmitters which have other output signals, provided that due allowance is made for such differences. This second edition cancels and replaces the first edition published in 1999 and constitutes a technical revision. The significant technical change with respect to the previous edition is as follows: 4.3 Load conditions,for pneumatic transmitters, load details have been added. This publication is to be read in conjunction with IEC 61298-1:2008 , IEC 61298-2:2008 , IEC 61298-3:2008 and IEC 61298-4:2008 .
