本特利（Bently Nevada）是一家專注于旋轉(zhuǎn)機械在線狀態(tài)監(jiān)測和機械保護的公司，其產(chǎn)品線涵蓋了超速保護器、通訊網(wǎng)關(guān)、振動傳感器以及檢測器等多種產(chǎn)品。以下是關(guān)于這些產(chǎn)品的詳細介紹：

超速保護器：

本特利的超速保護器，如3500/54M機械檢測系統(tǒng)，提供高度可靠、快速響應(yīng)的轉(zhuǎn)速表系統(tǒng)，用于超速保護。該模塊可以組合形成冗余雙通道或三通道表決系統(tǒng)，提供額外的安全保障。此外，超速保護器還可以與TSI（汽輪機安全監(jiān)視及保護系統(tǒng)）集成，實現(xiàn)在線監(jiān)測和預(yù)診斷功能，如不平衡、不對中、軸裂痕和軸承損壞等。

通訊網(wǎng)關(guān)：

本特利提供的通訊網(wǎng)關(guān)，如3500/92，具有廣泛的通訊能力。它可以通過以太網(wǎng)TCP/IP和串行（RS232/RS422/RS485）通訊協(xié)議將所有框架的監(jiān)測數(shù)據(jù)和狀態(tài)與過程控制和其它自動化系統(tǒng)集成。此外，它還支持與3500框架組態(tài)軟件和數(shù)據(jù)采集軟件的以太網(wǎng)通訊，并支持多種協(xié)議，如Modicon Modbus?、Modbus/TCP以及本特利協(xié)議等。

振動傳感器：

本特利振動傳感器是一種用于測量機器振動強度和頻率的設(shè)備。它通過采集振動信號并將其轉(zhuǎn)化為電信號，來判斷機器的工作情況。這些傳感器分為貼片式、夾持式和帶底座式三種類型，以適應(yīng)不同應(yīng)用場景的安裝需求。貼片式適合安裝在微小的機器設(shè)備上，夾持式適合安裝在大型設(shè)備上，而帶底座式則適合在環(huán)境溫度變化較大的場景下使用。本特利振動傳感器廣泛應(yīng)用于各類機器設(shè)備的振動監(jiān)測中，如汽車、船舶、飛機、機械加工、電力設(shè)備、礦山機械和建筑機械等，用于預(yù)警及故障診斷，提高設(shè)備的可靠性和穩(wěn)定性。

檢測器：

本特利也提供振動檢測器產(chǎn)品，如2300/20振動監(jiān)測器。這種監(jiān)測器為機器提供連續(xù)的振動監(jiān)測與保護功能，特別適用于風(fēng)機、壓縮機、水泵等機器的振動監(jiān)測。它廣泛應(yīng)用于發(fā)電廠、鋼鐵廠、化工廠、水處理廠、造紙廠、機械廠、水泥廠等企業(yè)行業(yè)。

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.
