3500/50 转速模块

Bently Nevada 3500/50

 3500是 Bently Nevada 提供的第一套能够被组态为多种冗余级别的系统， 从单一模块到双重电源，再到完全的TMR (三重模块冗余)组态。TMR组态方式有三个相同的监测器通道（或可选的传感器），采用3选2规则和专用继电器实现相互表决。这一特点使3500可以用于在任何情况下都不允许因电子故障或人为错误引起的电源、监测器通道或传感器发生误跳机或漏跳机的安全仪表系统中。
即使以非冗余方式应用，3500也是我们曾经提供的最可靠的系统，包含了多种自身监测功能，能够识别监测器模块以及与之相连的传感器的故障，通过相应的错误代码发布和确认故障， 并且当故障危及系统的正确运行时自动禁止通道运行。
