3500/50 133388-02 转速计监测模块4 通道

3500/50 转速表模块是一个两通道模块，它可接收来自涡流传感器或磁传感器（除非另外注明）的信号，可确定轴的转速、转子的加速度或转子的方向。它将这些测量量与用户可编程的报警点进行比较，当超过报警点时发出报警。

3500/50转速表模块可使用3500 框架组态软件进行编程，可将它组态成下列四种不同类型：  

1.   转速监测，设置点报警和速度带报警  

2.   转速监测，设置点报警和零转速指示 

3.   转速监测，设置点报警和转子加速度报警  

4.   转速监测，设置点报警和反转指示  

3500/50 可被组态成向3500框架背板提供键相位信号，供其它监测器使用，因此不必再在框架内安装键相位模块。3500/50还有一个峰值保持功能；它可以存储机器曾达到的最高转速、最高反转速度或反转的数量（取决于所选择的通道类型）。这些峰值可由使用者复位。  

应用说明  

•  本特利转速表模块不单独使用或作为某一部件用于转速控制或超速保护系统。  •  

本特利转速表模块不为转速控制或超速保护系统提供保护冗余和响应转速。   •  

模拟量比例输出只用于数据收集、图表记录或显示。另外，转速的警告设置点只是用于通知目的。  

•  磁传感器不使用反转选项，因为这些传感器在低转速时不能为检测电路提供清晰边沿，这将引起 

错误的反转指示。  

•  磁传感器不推荐使用零转速选项，因为这些传感器在低转速时不能为检测电路提供清晰边沿。

The 3500/50 tachometer module is a two-channel module that receives signals from eddy current sensors or magnetic sensors (unless otherwise noted) to determine the speed of the shaft, the acceleration of the rotor or the direction of the rotor. It compares these measurements with a user-programmable alarm point and sends an alarm when the point is exceeded.

The 3500/50 tachometer module can be programmed using the 3500 Frame configuration software, which can be configured into the following four different types:

1. Speed monitoring, setting point alarm and speed belt alarm

2. Speed monitoring, setting point alarm and zero speed indication

3. Speed monitoring, setting point alarm and rotor acceleration alarm

4. Speed monitoring, setting point alarm and reverse indication

The 3500/50 can be configured to provide a key phase signal to the 3500 frame backplane for use by other monitors, eliminating the need to install a key phase module in the frame. The 3500/50 also has a peak-holding function; It can store the highest RPM the machine has ever achieved, the highest reverse speed, or the number of reversals (depending on the channel type chosen). These peaks can be reset by the user. 

Application description

• Bentley tachometer modules are not used alone or as part of a speed control or overspeed protection system. •

Bentley tachometer modules do not provide protection redundancy and responsive speed for speed control or overspeed protection systems. •

Analog proportional output is used only for data collection, chart recording or display. In addition, the speed warning setting point is for notification purposes only. 

• Magnetic sensors do not use the reverse option because these sensors do not provide clear edges for the detection circuit at low RPM, which will cause

Incorrect inversion indication. 

• The zero speed option is not recommended for magnetic sensors because these sensors do not provide clear edges for the detection circuit at low speeds.
