描述
本特利内华达1900/65A通用设备监测器
这款监测器是一款经济高效且灵活的解决方案，可将持续监测扩展到不太关键但仍然必不可少的机械设备。
1900/65A监测器的主要特点：
输入：
四个传感器输入：可配置为支持2线和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通道组合的“正常”、“警报”和“危险”状态。这些状态可用于警报或自动关机。
四路4-20 mA记录仪输出：提供模拟输出信号，用于趋势分析以及与其他控制系统（例如DCS、PLC）集成。
专用缓冲输出：提供每个传感器输入的原始信号，用于外部分析。
信号处理：每个通道可连续计算多个变量（例如峰值/均方根振动、位置、速度、温度），并具有独立的积分和滤波控制。
报警：具有两级报警：警报和危险，并可配置设定值。
通信：
以太网(Modbus TCP)：用于与DCS、PLC、SCADA系统或本特利内华达的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：通过以太网连接下载到监测仪的用户友好型软件进行配置。配置存储在非易失性存储器中。
电源输入：通常为18至36 VDC。可提供外部电源，用于110/220 VAC转换。
物理设计：紧凑坚固，适用于工业环境。可采用DIN导轨安装或隔板安装。
167699-020（显示模块）
167699-020（通常称为167699-02）是1900/65A通用设备监视器的可选显示模块。
功能：该模块提供本地显示屏和键盘，允许用户：
直接在机器上查看通道信息和监控变量。
进行细微的配置更改。
灵活性：该显示器可直接安装在1900/65A监视器模块上，或通过单根电缆连接，最远可连接到75米（250英尺）远的地方，从而提供灵活的安装。
特点：通常采用背光彩色LCD显示屏，并带有用于导航的软键。
典型应用：
本特利内华达1900/65A系统非常适合各种“辅助设备”和重要机械监控，包括：
泵、电机、鼓风机和风扇
冷却塔风扇
小型往复式压缩机
离心机
粉碎机
小型水轮机
Bently Nevada 1900/65A General Purpose Equipment Monitor
This monitor is a cost-effective and flexible solution for extending continuous monitoring to less critical but still essential machinery.
Key Features of the 1900/65A Monitor:
Inputs:
Four Transducer Inputs:Configurable to support 2-and 3-wire accelerometers,velocity sensors,or proximity sensors 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”statuses of any channel or combination of channels.These can be used for alarms or automatic shutdowns.
Four 4-20 mA Recorder Outputs:Provides analog output signals for trending and integration with other control systems(e.g.,DCS,PLC).
Dedicated Buffered Output:Provides the raw signal from each transducer input for external analysis.
Signal Processing:Capable of continuous calculation of multiple variables per channel(e.g.,peak/RMS vibration,position,speed,temperature),with independent integration and filter control.
Alarming:Features two levels of alarms:Alert and Danger,with configurable setpoints.
Communications:
Ethernet(Modbus TCP):For digital communication with DCS,PLCs,SCADA systems,or Bently Nevada’s System 1 software.
RS-232/RS-485 Serial Port:Software-configurable for Modbus RTU communication.
Configuration:Configured via user-friendly software downloaded to the monitor through the Ethernet connection.Configuration is stored in non-volatile memory.
Power Input:Typically operates on 18 to 36 VDC.An external power supply is available for 110/220 VAC conversion.
Physical Design:Compact and rugged,suitable for industrial environments.Can be DIN-rail mounted or bulkhead mounted.
The 167699-020(Display Module)
The 167699-020(often seen as 167699-02)is the optional Display Module for the 1900/65A General Purpose Equipment Monitor.
Function:This module provides a local display and keypad,allowing users to:
View channel information and monitor variables directly at the machine.
Make minor configuration changes.
Flexibility:The display can be mounted directly onto the 1900/65A monitor module or up to 75 meters(250 feet)away,connected via a single cable,offering flexibility in installation.
Features:Often a backlit color LCD with soft keys for navigation.
