The vibration velocity sensor SDJ-SG-2H is used in conjunction with a vibration monitor to enable continuous and long-term vibration condition monitoring. Its working principle is based on the primary element that converts mechanical energy into electrical energy. The sensor is fixed inside by two coils, and a magnet in the middle is connected to the housing through a spring. When the equipment vibrates, the magnet moves in the coil, generating an induced electromotive force. This voltage is proportional to the speed of the housing, so it is called a velocity sensor.

The vibration velocity SDJ-SG-2H sensor has the following features and advantages:

1. Small and compact design: The SDJ-SG-2H is small in size and easy to install in a suitable position of any mechanical equipment without burdening the equipment itself.

2. Good sealing performance: The sensor has good sealing performance and can adapt to various harsh working environments, such as high temperature, high humidity, oil pollution, etc.

3. Long life: Due to the use of highly durable materials, the SDJ-SG-2H has a long service life, reducing the frequency and cost of replacement and maintenance.

4. Dual coil structure: SDJ-SG-2H adopts a dual coil structure design, which enables effective signals to be superimposed and interference signals to be attenuated, thereby effectively improving the sensor’s anti-interference ability.

5. High-precision monitoring: SDJ-SG-2H can accurately convert mechanical vibrations into electrical signals, providing reliable data support for vibration analysis.

In practical applications, the vibration velocity sensor SDJ-SG-2H has proven its value in mechanical condition monitoring. For example, in the field of wind power generation, the operating condition monitoring of wind turbines is essential to ensure power generation efficiency and equipment safety. SDJ-SG-2H can monitor the vibration of the turbine in real time, detect abnormalities in time and issue warnings, avoiding possible equipment damage and downtime losses. In the steel industry, vibration monitoring of large equipment such as rolling mills is equally important. The application of SDJ-SG-2H can help operators understand the equipment status in a timely manner and ensure production continuity and product quality.

In summary, the vibration velocity sensor SDJ-SG-2H is a high-precision and high-reliability condition monitoring device. It provides important data support for the health status analysis of mechanical equipment by converting mechanical vibrations into electrical signals. Its small size, good sealing, long service life and double coil structure make it an indispensable monitoring tool in industrial production.
