RS8109 Low Frequency Vibration Speed Sensor

The RS8109 low-frequency vibration velocity sensor is a new type of sensor developed and produced by our company. It has strong universality and can be installed vertically or horizontally. It also has high waterproof performance (up to IP68 protection level) The RS8109 low-frequency vibration sensor is a seismic vibration velocity sensor that uses a low-frequency extension correction circuit to reduce the natural frequency of its output characteristics to 1/20 to 1/40 of the original, which can reach 0.5Hz or lower. The RS8109 low-frequency vibration sensor is suitable for vibration monitoring of large hydroelectric generators and low-speed rotating machinery, machine tool accuracy testing, earthquake monitoring and geological exploration, vibration analysis of high-rise buildings and structures, dynamic deformation and vibration testing of roadbeds and bridges, and can be used in security and other fields.
