990-04-70-01-00 本特利振动变送器
990振动变送器主要用于主要用于离心式空气压缩机或小的泵,马达,提供4至20 mA比例振动信号作为他们的机械控制系统的输入。此外还用于离心式空气压缩机的原始设备制造商(OEM)或小型泵,电机或风机,他们希望提供简单的4至20 mA比例振动信号作为其机械控制系统的输入。变送器是一个2线环路供电设备,可接受来自我们的3300 NSv *接近探头及其匹配的延长电缆(5米和7米系统长度选件)的输入。变送器将信号调节为适当的峰峰值振幅工程单位,并将该值作为4至20 mA比例的工业标准信号,作为机械保护报警和逻辑出现的控制系统的输入1。
990变送器具有以下显着特点:
集成Proximitor *传感器不需要外部设备
非隔离的“PROX OUT”和“COM”端子以及一个同轴连接器,为诊断2提供动态振动和间隙电压信号输出。
变送器标签下的非交互式零点和量程电位器支持回路调整。
测试输入引脚,用于快速验证回路信号输出,使用函数发生器作为输入。
上电抑制电路消除了线路电压瞬变引起的信号错误。
不正常/信号失效电路可防止由于接近探针故障或连接松动导致的高输出或错误报警。
选择DIN导轨夹或舱壁安装螺钉作为标准选件,可简化安装。
高湿度(高达100%冷凝)环境的盆栽结构。
与3300 NSv接近探头的兼容性允许传感器安装在离心式空气压缩机的典型离心式空气压缩机的最小间隙范围内。
