Overview

Speed monitoring device, equipped with vibration speed sensor, can measure the amplitude of bearing vibration of various rotating machinery, and monitor the vertical and horizontal vibration of rotating machinery. It is particularly suitable for machines with ball bearings, where the vibration of bearings can be transmitted to the casing for continuous measurement and protection of rotating machinery. Special attention should be paid to the installation of sensors to avoid reducing the amplitude of the sensor, changing the frequency effect, or generating signals that cannot represent the true vibration of the machine. This monitoring device is particularly suitable for situations where a large number of vibration points need to be measured, such as motors, compressors, fans, and centrifugal machines.

Main functions:

Monitoring and protection of the rotational speed of rotating machinery such as steam turbines, coal mills, fans, reducers, water pumps, centrifuges, balancing machines, and air compressors.

Function Description:

The measured value and alarm set value can be displayed separately on the LED digital tube.

When the alarm setting value is exceeded, the alarm indicator light will turn on, and at the same time, a switch signal will be output on the rear panel to protect the monitored equipment. The alarm setting delay can be adjusted within the range of 1-60 seconds to prevent false alarms caused by on-site interference..
