工业过程控制系统用传送器.第2部分:检验和常规试验方法

[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 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功能的变送器。输出信号，前提是对这种差异给予适当的考虑。智能变送器的检查和例行测试方法参见IEC 60770-3。对于某些类型的变送器，其中传感器是一个组成部分，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）。本标准旨在提供检查和例行检查的技术方法。发射机测试，例如验收测试或维修后。为了进行全面评估，应使用分别针对模拟或智能变送器的 IEC 60770-1 和/或 IEC 60770-3。可接受性能的定量标准应由制造商和用户之间达成协议建立。根据协议，测试不必由认可的实验室进行。 [外文原描述]： IEC 60770-2:2010 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. It is intended to provide technical methods for inspection and routine testing of transmitters, for instance, for acceptance tests or after repair. For a full evaluation, IEC 60770-1 and/or IEC 60770-3, respectively for analogue or intelligent transmitters shall be used. This third edition cancels and replaces the second edition published in 2003 and constitutes a technical revision. The significant technical change with respect to the previous edition is: the sequence in content has been reordered in Clause 5. 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 .
