ultra-trak750向您展示以下预警信号：
机械故障
阀门泄漏
流动中断
通过检测超声波振幅的变化进行电弧放电
怎么运行的：
ultra-trak750可感应操作设备产生的高频辐射。可以在120分贝的宽动态范围内设置基线阈值。一旦设置好ultra-trak750，就会监测40分贝范围内超声波振幅的变化。ultra-trak750可以与其他设备连接，以提供警报或跟踪潜在问题。在某些情况下，ultra-trak750可用于增加声级，例如警告阀门泄漏或轴承故障的发生。幅度下降可用于发出线路流量中断或机器停机报警。
ultra-trak750可以在安装后立即防止意外停机和产品损失。ultra-trak750被动监测操作设备产生的超声波。由于其4-20 ma电流输出和纯解调输出，它可以方便地连接到报警或记录仪进行数据记录。
坚固耐用的ultra-trak750采用不锈钢制成，具有防水和防尘功能，这意味着它可以在一些具挑战性的环境中进行外部安装。结合120 db的极宽动态范围和灵敏度调节; 该传感器可满足您苛刻的传感需求。
ue ultra-trak750功能：
1.用于分析的解调输出
2.动态范围：120 db
3.感应范围40 db：一旦设置了声级，就有40 db的监听范围。
4.峰值频率响应：40 khz
5.外部数据记录或录音的输出。
