 Vibration device vibration transmitter CD-21T, SLMCD-21T, SLMCD-21TS, SLMCD-21

. The system is suitable for online monitoring and protection of all large and medium-sized rotating machinery, including steam turbines, water turbines, blowers, motors, water pumps, etc. The system can continuously measure and monitor safety-related shaft vibration, bearing vibration, swing, eccentricity, axial displacement, differential expansion/speed and other process quantities (such as temperature, pressure, load, etc.) and various main mechanical parameters. The monitoring and protection device for rotating machinery is mainly applicable to fields such as electric power, steel, building materials, and chemical industry. Continuous monitoring and measurement of the controller, starting valve, oil motor, thermal expansion, oil level of the fuel tank, temperature, etc., which is convenient for users to analyze and maintain the working conditions of the machine. When the measuring point of the machine exceeds the normal use value, the device will immediately send out an alarm and danger signal, so that your machine can be protected in time to avoid unnecessary economic losses. The protector adopts a high-performance switching power supply and adds a high-low pass filter and an isolation barrier, which greatly improves the anti-interference ability, stable performance, safety and reliability, and high performance-price ratio.
