Product Description

SDJ-3B/3L Multi-function Vibration Monitoring and Protection Instrument

The SDJ-3B and SDJ-3L vibration monitoring and protection devices are advanced multi-functional instruments designed for rotating machinery vibration monitoring. These devices utilize two independent SG-2 type velocity sensor signals to continuously display amplitude or velocity values on LED digital displays for each channel.

System Overview

Available in both panel-mounted and wall-mounted versions, these monitoring and protection devices are primarily suitable for critical applications in power generation, steel production, building materials, and chemical industries.
