MLV/S-9一體化低頻振動(dòng)速度傳感器

MLV/S-9 Vibration Velocity Sensor

1．概述

MLV/S-9一體化低頻振動(dòng)速度傳感器主要安裝在各種旋轉(zhuǎn)機(jī)械裝置的軸承蓋上（如汽輪機(jī)、壓縮機(jī)、風(fēng)機(jī)和泵等）。它是由運(yùn)動(dòng)線圈切割磁力線而輸出電壓的電磁式傳感器，因此具有工作時(shí)不需要供給電源、安裝容易等特點(diǎn)。

1. Overview

The PR-1020 vibration sensor is mainly installed on the bearing housings of various rotating machinery (such as steam turbines, compressors, fans, pumps, etc.). As an electromagnetic sensor that outputs voltage by moving coils cutting magnetic lines, it features no external power supply required for operation and easy installation.When connected with a vibration severity monitor, it can measure various parameters such as displacement and velocity.
