SDJ-3NA Shaft Vibration Monitoring and Protection Instrument
High-precision dual-channel vibration monitoring transmitter for industrial protection systems
SDJ-3NA Shaft Vibration Monitoring and Protection Instrument | High-precision Dual-channel Vibration Monitoring Transmitter 0
System Overview
The SDJ-3NA shaft vibration monitoring and protection instrument (intelligent type) receives vibration signals from two independent 3800XL eddy current sensor sources. The amplitude values of both signals are continuously displayed on the LED digital display with decimal point precision. This protection system features high-pass and low-pass filters with isolation barriers, significantly enhancing anti-interference capability. Available in panel-mounted and wall-mounted versions, it is primarily designed for applications in power generation, steel production, building materials, and chemical industries.
