Description

Technical Field

[0002] A total of 10 sensors are installed in the transmission chain vibration monitoring module, including 5 low-frequency sensors, 4 full-frequency sensors, and 1 speed sensor. The vibration monitoring collector is used to continuously and high-speed collect and calculate the acceleration signal of the acceleration sensor and push it to the vibration monitoring server at the station end.

[0003] When installing the speed sensor, it is necessary to meet the following requirements: the center of the speed sensor coincides with the center of each circular hole to be measured, and the center point of the speed sensor and the center point of each circular hole to be measured are on the same arc line. The end of the sensor is kept at a distance of 3mm to 5mm from the end face of the object to be measured. After the adjustment is completed, tighten the speed sensor. When the installation position is relatively narrow, it is easy to cause the distance between the end of the sensor and the end face of the object to be measured to be less than 3mm to 5mm, or even difficult to install, affecting the accuracy of the measurement.
