工业过程控制系统 - 具有模拟输入和双或多位置输出的仪器 - 第2部分:检查和日常测试指导

[中文适用范围]： IEC 61003 的这一部分提供了带有两位或多位输出@的电气和气动仪器的检查和例行测试@例如@用于验收测试或维修后@的指南，并且应与IEC 61003-1结合使用： 2016 IEC 61298-2:2008 和 IEC 61298-3:2008。 IEC 61003 的这一部分适用于使用连续信号测量值的电气和气动工业过程仪器@。设定点值可以是机械信号（位置@力@等）或标准信号。这些仪器可用作控制器或警报开关和其他类似用途。可接受性能的定量标准应由制造商和用户之间达成协议确定，并且测试报告应阐明进行了哪些测试。本标准的要求经制造厂和用户同意后有效。 [外文原描述]： IEC 61003-2:2016 gives guidelines for inspection and routine testing of electrical and pneumatic instruments with two- or multi-position output, for instance, for acceptance tests or after repair. It is applicable to electrical and pneumatic industrial-process instruments, using measured values that are continuous signals. The set point value may be either a mechanical (position, force, etc.) or a standard signal. These instruments may be used as controllers or as switches for alarms and other similar purposes. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - use of the term "two- or multi-position output" instead of "two- or multi-state instrument" (see Scope); - use of the term "differential gap" instead of "switching differential" (see Table 1 No 2); - use of the term "dielectric strength" instead of "isolation test" (see Table 1 No 5). This publication is to be read in conjunction with IEC 61003-1:2016 , IEC 61298-2:2008 and IEC 61298-3:2008
