MY66E Wireless Vibration Sensor

MY66E Wireless Monitoring and Analysis System

1. Overview

The MY66E wireless vibration temperature transmitter is a newly developed product by our company. It can monitor the vertical and horizontal vibration and temperature of rotating equipment in real time for a long time. The data is transmitted to a PC, and through the analysis center, it accurately determines common faults such as unbalanced rotating machinery, loose structure, and misalignment. And it is equipped with domestic and foreign GB/T6075.3-2001 (vibration intensity) status recognition, which can analyze, predict, and actively upload equipment status.
