BENTLY 1900/65A通用设备监测器
这是一款灵活且经济高效的系统，旨在将持续机械监测扩展到关键资产之外。它通过提供早期故障检测和保护，帮助用户实施基于状态的维护策略。
1900/65A的核心功能：
输入：
四个传感器输入：可配置为2线或3线加速度计、速度传感器或接近传感器，用于振动和位置测量。
四个温度输入：支持各种热电偶类型（E、J、K、T）以及2线或3线RTD。
转速通道：测量转速范围为100至100,000 RPM。
输出：
六个继电器输出：用户可配置任意通道或组合的“正常”、“警报”和“危险”警报。这些警报可以触发外部警报或自动关机。
四路4-20 mA记录仪输出：提供模拟输出，用于将趋势数据传送至DCS、PLC或其他控制系统。
专用缓冲输出：提供每个传感器通道的原始信号输出，以便使用便携式诊断工具进行外部分析。
信号处理：通过独立的积分和滤波器控制，连续计算每个通道的多个变量，包括用于轴承和齿轮箱故障检测的包络等高级选项。
报警：提供两级报警：警报和危险，并带有用户可编程的设定值。
通信：
以太网(Modbus TCP)：用于与控制系统（DCS、PLC、SCADA）或本特利内华达System 1软件进行数字通信。
RS-232/RS-485串行端口：可通过软件配置，用于Modbus RTU通信。
配置：通过PC上的直观软件进行配置，设置存储在非易失性存储器中。
坚固耐用的设计：专为承受恶劣的工业环境而设计，具有广泛的工作温度范围和坚固的结构。它可以采用DIN导轨或隔板安装。
1900/65A-01-02-01-00-000配置明细
后缀“01-02-01-00-000”指定了此特定设备选择的选项：
01（第一栏-电源选项）：18至36 VDC电源输入。（注意：可选的外部电源可用于110-220 VAC转换，但此设备配置为直流电源）。
02（第二栏-显示选项）：远程显示。这意味着显示器附带一个显示模块，该模块可以与主显示器模块分开安装，并通过电缆连接（通常距离最远75米/250英尺）。这提供了安装灵活性。
01（第三栏-安装选项）：DIN导轨安装。这表示监控模块设计为可夹在控制柜内的标准DIN导轨上。
00（第四字段-认证选项）：无特定机构认证。这意味着它没有特定的认证，例如ATEX、CSA或UL防爆等级（尽管它可能仍然符合一般工业标准）。
00（第五字段-通信选项）：无Modbus通信。此配置意味着它缺少用于与其他系统进行数字通信的集成Modbus网关。数据通常通过4-20 mA输出或缓冲输出访问。
000（第六字段-特殊选项/版本）：通常表示没有特殊选项或标准版本。
BENTLY 1900/65A General Purpose Equipment Monitor
This is a flexible and cost-effective system designed to extend continuous machinery monitoring beyond just critical assets.It helps users implement condition-based maintenance strategies by providing early fault detection and protection.
Core Capabilities of the 1900/65A:
Inputs:
Four Transducer Inputs:Configurable for 2-or 3-wire accelerometers,velocity sensors,or proximity sensors,allowing for vibration and position measurements.
Four Temperature Inputs:Supports various thermocouple types(E,J,K,T)and 2-or 3-wire RTDs.
Speed Channel:Measures speed from 100 to 100,000 RPM.
Outputs:
Six Relay Outputs:User-configurable for”OK,””Alert,”and”Danger”alarms for any channel or combination.These can trigger external alarms or automatic shutdowns.
Four 4-20 mA Recorder Outputs:Provides analog output for trending data to a DCS,PLC,or other control systems.
Dedicated Buffered Output:Offers raw signal output from each transducer channel for external analysis using portable diagnostic tools.
Signal Processing:Continuously calculates multiple variables per channel with independent integration and filter control,including advanced options like enveloping for bearing and gearbox fault detection.
Alarming:Features two levels of alarms:Alert and Danger,with user-programmable setpoints.
Communication:
Ethernet(Modbus TCP):For digital communication with control systems(DCS,PLC,SCADA)or Bently Nevada’s System 1 software.
RS-232/RS-485 Serial Port:Software-configurable for Modbus RTU communication.
Configuration:Configured via intuitive software on a PC,with settings stored in non-volatile memory.
Rugged Design:Built to withstand harsh industrial environments,with a wide operating temperature range and robust construction.It can be DIN-rail or bulkhead mounted.
Breakdown of 1900/65A-01-02-01-00-000 Configuration
The suffix”01-02-01-00-000″specifies the options chosen for this particular unit:
01(First field-Power Option):18 to 36 VDC power input.(Note:An optional external supply is available for 110-220 VAC conversion,but this unit is configured for DC).
02(Second field-Display Option):Remote Display.This means the monitor comes with a display module that can be mounted separately from the main monitor module,connected via a cable(typically up to 75 meters/250 feet away).This offers installation flexibility.
01(Third field-Mounting Option):DIN-rail mount.This indicates the monitor module is designed to clip onto a standard DIN rail within a control cabinet.
00(Fourth field-Approvals Option):No specific agency approvals.This means it does not come with specific certifications like ATEX,CSA,or UL explosion-proof ratings(though it may still meet general industrial standards).
00(Fifth field-Communications Option):No Modbus communications.This configuration means it lacks the integrated Modbus gateway for digital communication with other systems.Data would typically be accessed via the 4-20 mA outputs or the buffered outputs.
000(Sixth field-Special Options/Revision):Usually indicates no special options or a standard revision.
