Bently Nevada 991-06-70-01-CN

Brand:Bently Nevada

Model: 991-06-70-01-CN

Status: New/Used

The 991 Thrust Transmitter is intended primarily for the original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans who prefer to provide a simple 4 to 20 mA proportional axial displacement (thrust) signal as the input to their machinery control system. The transmitter is a 2-wire, loop-powered device that accepts input from our 3300 NSv proximity probe and its matching extension cable (available in 5 m and 7 m system length options). The transmitter conditions the signal into appropriate engineering units proportional to the shaft’s axial position1, and provides it as a 4 to 20 mA industry-standard signal for input to the control system where machinery protection alarming and logic occurs2.

991 Thrust Transmitter

Description

The 991 transmitter provides the following notable features:

1) Integrated Proximitor Sensor requires no external unit

2) Non-isolated "PROX OUT " and "COM" terminals plus a coaxial connector provide a dynamic vibration and gap voltage signal output for diagnostics3.

3) Non-interacting zero and span potentiometers under the Transmitter label supports loop adjustment.

4) Test Input pin allows quick verification of loop signal output, using a variable DC voltage source as the input.

5) A Power-up Inhibit circuit eliminates signal errors due to line voltage transients.

6) A Not OK/Signal Defeat circuit prevents high outputs or false alarms due to a faulty proximity probe or loose connection.

7) Choice of DIN-rail clips or bulkhead mounting screws as standard options simplifies mounting.

8) Potted construction for high humidity (up to 100% condensing) environments.

9) Compatibility with 3300 NSv proximity probe allows transducer installation in small areas with minimal clearance, typical of centrifugal air compressors.

991推力变送器
描述
991推力变送器主要适用于离心式空气压缩机或小型泵、电机或风扇的原始设备制造商（OEM），他们更喜欢提供简单的4至20mA比例轴向位移（推力）信号作为其机械控制系统的输入。变送器是一个2线、回路供电的设备，可接受我们3300 NSv接近探头及其匹配的延长电缆（有5米和7米系统长度选项）的输入。变送器将信号调节为与轴的轴向位置成比例的适当工程单位1，并将其作为4至20mA的行业标准信号提供给发生机械保护报警和逻辑的控制系统2。
991发射机具有以下显著特点：
1）集成前置器传感器不需要外部单元
2）非隔离的“PROX OUT”和“COM”端子加上同轴连接器为诊断提供动态振动和间隙电压信号输出3。
3）变送器标签下的非交互式零点和量程电位计支持回路调整。
4）测试输入引脚允许使用可变直流电压源作为输入快速验证回路信号输出。
5）加电抑制电路消除了由于线路电压瞬变引起的信号错误。
6） Not OK/Signal Defeat电路可防止因接近探头故障或连接松动而导致的高输出或误报。
7）选择DIN导轨夹或舱壁安装螺钉作为标准选项简化了安装。
8）适用于高湿度（高达100%冷凝）环境的盆栽结构。
9）与3300 NSv接近式探头的兼容性允许传感器安装在间隙最小的小区域，这是离心空气的典型特征压缩机。
