MLV-8振動傳感器/航振牌

MLV-8 Vibration Velocity Sensor

1．概述

MLV-8振動傳感器/航振牌主要安裝在各種旋轉(zhuǎn)機械裝置的軸承蓋上（如汽輪機、壓縮機、風機和泵等）。它是由運動線圈切割磁力線而輸出電壓的電磁式傳感器，因此具有工作時不需要供給電源、安裝容易等特點。

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.
