本特利（Bently Nevada）是一家专注于旋转机械在线状态监测和机械保护的公司，其产品线涵盖了超速保护器、通讯网关、振动传感器以及检测器等多种产品。以下是关于这些产品的详细介绍：

超速保护器：

本特利的超速保护器，如3500/54M机械检测系统，提供高度可靠、快速响应的转速表系统，用于超速保护。该模块可以组合形成冗余双通道或三通道表决系统，提供额外的安全保障。此外，超速保护器还可以与TSI（汽轮机安全监视及保护系统）集成，实现在线监测和预诊断功能，如不平衡、不对中、轴裂痕和轴承损坏等。

通讯网关：

本特利提供的通讯网关，如3500/92，具有广泛的通讯能力。它可以通过以太网TCP/IP和串行（RS232/RS422/RS485）通讯协议将所有框架的监测数据和状态与过程控制和其它自动化系统集成。此外，它还支持与3500框架组态软件和数据采集软件的以太网通讯，并支持多种协议，如Modicon Modbus®、Modbus/TCP以及本特利协议等。

振动传感器：

本特利振动传感器是一种用于测量机器振动强度和频率的设备。它通过采集振动信号并将其转化为电信号，来判断机器的工作情况。这些传感器分为贴片式、夹持式和带底座式三种类型，以适应不同应用场景的安装需求。贴片式适合安装在微小的机器设备上，夹持式适合安装在大型设备上，而带底座式则适合在环境温度变化较大的场景下使用。本特利振动传感器广泛应用于各类机器设备的振动监测中，如汽车、船舶、飞机、机械加工、电力设备、矿山机械和建筑机械等，用于预警及故障诊断，提高设备的可靠性和稳定性。

检测器：

本特利也提供振动检测器产品，如2300/20振动监测器。这种监测器为机器提供连续的振动监测与保护功能，特别适用于风机、压缩机、水泵等机器的振动监测。它广泛应用于发电厂、钢铁厂、化工厂、水处理厂、造纸厂、机械厂、水泥厂等企业行业。

Bently Nevada is a company specializing in online condition monitoring and mechanical protection of rotating machinery. Its product line includes a variety of products such as overspeed protectors, communication gateways, vibration sensors, and detectors. Here is a detailed introduction to these products:

Overspeed protector:

Bentley's overspeed protector, such as the 3500/54M mechanical detection system, provides a highly reliable and responsive tachometer system for overspeed protection. This module can be combined to form a redundant dual channel or three channel voting system, providing additional security guarantees. In addition, the overspeed protector can also be integrated with TSI (Turbine Safety Monitoring and Protection System) to achieve online monitoring and pre diagnosis functions, such as imbalance, misalignment, shaft cracks, and bearing damage.

Communication gateway:

The communication gateway provided by Bentley, such as 3500/92, has a wide range of communication capabilities. It can integrate monitoring data and status of all frameworks with process control and other automation systems through Ethernet TCP/IP and serial (RS232/RS422/RS485) communication protocols. In addition, it also supports Ethernet communication with 3500 rack configuration software and data acquisition software, and supports multiple protocols such as Modicon Modbus ®、 Modbus/TCP and Bentley protocols, etc.

Vibration sensor:

Bentley vibration sensor is a device used to measure the intensity and frequency of machine vibration. It determines the working condition of the machine by collecting vibration signals and converting them into electrical signals. These sensors are divided into three types: SMT, clamp, and base mounted, to meet the installation requirements of different application scenarios. The SMT type is suitable for installation on small machinery, the clamp type is suitable for installation on large equipment, and the base type is suitable for use in scenarios with significant temperature changes in the environment. Bentley vibration sensors are widely used in vibration monitoring of various types of machinery and equipment, such as automobiles, ships, airplanes, mechanical processing, power equipment, mining machinery, and construction machinery, for early warning and fault diagnosis, improving equipment reliability and stability.

Detector:

Bentley also offers vibration detector products, such as 2300/20 vibration monitors. This type of monitor provides continuous vibration monitoring and protection functions for machines, especially suitable for vibration monitoring of machines such as fans, compressors, and water pumps. It is widely used in power plants, steel plants, chemical plants, water treatment plants, paper mills, machinery plants, cement plants and other enterprise industries.
