Bently 3500/25 增强型键相模块

Bently 3500/25是Bently Nevada开发的一款增强型键相模块。它是一个半高、双通道模块，用于将Keyphasor信号传送到3500机架中的监视器模块。在轴上的键相标记与键相传感器对齐时，模块使用磁性拾音器或接近探头检测对齐情况，并将输入信号转换为数字键相信号。

在常规设置中，3500机械保护系统最多可接受四个键相信号，而在配对配置中，最多可接受八个。旋转轴或齿轮的每转一次或每转多个事件的脉冲（称为键相信号）可用于精确检测定时。因此，轴转速和矢量特性（如1X振动幅度和相位）可以通过3500监控模块和外部诊断工具进行测量。

此外，Bently 3500/25 149369-01的主要作用是作为工业自动化系统中的信号转换器，将输入的模拟信号转换为数字信号，或者将数字信号转换为模拟信号。它具有体积小、精度高、稳定性好、线性度优等优点，能够提供准确的测量结果和可靠的控制系统。

在实际应用中，Bently 3500/25可以应用于多个领域。在能源行业，它可以用于监测和保护发电机、涡轮机、发电机组和其他关键旋转设备。在石油和天然气行业，它可以用于监测和保护泵、压缩机、离心机等旋转机械设备。在化工工业，它同样可以应用于监测和保护关键设备，如离心泵、风机、压缩机等。

The Bently 3500/25 is an enhanced bond phase module developed by Bently Nevada. It is a semi-tall, dual-channel module for transmitting Keyphasor signals to monitor modules in 3500 racks. When the key phase marker on the shaft is aligned with the key phase sensor, the module uses a magnetic pickup or proximity probe to detect the alignment and convert the input signal into a digital key trust signal.

The 3500 mechanical protection system accepts up to four key trust numbers in a regular setup, and up to eight in a paired configuration. Pulses of one or more events per revolution of a rotating shaft or gear (called key confidence signals) can be used to accurately detect timing. As a result, shaft speed and vector characteristics such as 1X vibration amplitude and phase can be measured using the 3500 monitoring module and external diagnostic tools.

In addition, the main role of the Bently 3500/25 149369-01 is as a signal converter in industrial automation systems, converting input analog signals to digital signals, or converting digital signals to analog signals. It has the advantages of small size, high precision, good stability, good linearity, and can provide accurate measurement results and reliable control system.

In practical application, the Bently 3500/25 can be applied in multiple fields. In the energy industry, it can be used to monitor and protect generators, turbines, generator sets and other critical rotating equipment. In the oil and gas industry, it can be used to monitor and protect rotating machinery such as pumps, compressors and centrifuges. In the chemical industry, it can also be used to monitor and protect critical equipment, such as centrifugal pumps, fans, compressors, etc.
