8200-201 数字超速跳闸设备 感应原动机速度

【产品详情】

ProTech 203 数字超速跳闸设备，通过三个磁性拾音器 （MPU） 感应原动机速度。伍德沃德型号 8200-202

ProTech 203超速保护系列有三种不同的电源版本。8200-202 型是通电跳闸型号的 120 Vac/dc 输入版本。该伍德沃德模块是一款坚固可靠的数字超速跳闸设备，采用三分之二的硬件投票方法。8200-202 的三个独立速度感应单元使用磁性拾音器 （MPU） 每 5 ms 对速度进行一次采样，然后执行单独的速度计算。

除了这种硬件投票方法的可靠性外，8200-202 型的多单元设计还允许对每个单元进行单独测试。当一个速度感应单元正在测试时，另外两个单元保持在线并处于控制状态。此功能部分是通过内置频率发生器实现的。

此超速保护设备上的三个单元中的每一个都有自己的电源、触摸板和 LCD 显示屏。前面板具有指示系统运行错误的 LED。

8200-202 型应安装在可以保持 –25 至 +60 °C（–13 至 +140 °F）工作温度范围的位置;防止阳光直射、冷凝和高振动;并且通风充足。

【英文介绍】

The ProTech 203 digital overspeed trip device senses the prime mover speed via three magnetic pickups (MPUs). Woodward model 8200-202

The ProTech 203 overspeed protection series is available in three different power supply versions. Model 8200-202 is a 120 Vac/dc input version of the power trip model. The Woodward module is a robust and reliable digital overspeed trip device with a two-thirds hardware voting method. The 8200-202's three independent speed sensing units use magnetic pickups (MPUs) to sample the speed every 5 ms and then perform individual speed calculations.

In addition to the reliability of this hardware voting method, the multi-cell design of the Model 8200-202 also allows each cell to be tested individually. While one speed sensing unit is being tested, the other two units remain online and in control. This function is partly achieved through a built-in frequency generator.

Each of the three units on this overspeed protection device has its own power supply, touchpad, and LCD display. The front panel has leds that indicate that the system is operating incorrectly.

Model 8200-202 shall be installed in a position where the operating temperature range of -25 to +60 °C (-13 to +140 °F) can be maintained; Protection from direct sunlight, condensation and high vibration; And there's plenty of ventilation.
