TRLS-9 ultra-low frequency vibration sensor is an inertial sensor.

The ultra-low frequency vibration sensor uses the principle of magnetoelectric induction to convert the vibration signal into voltage signal. At the same time, a set of low frequency expansion circuit is used to reduce the natural frequency of the mechanical structure of the sensor, so that its initial frequency can be selected from 0.05Hz to 0.7hz. The sensor has the characteristics of anti vibration, shock resistance and good low frequency output characteristics.

Application Introduction:

  TRLS-9 ultra-low frequency vibration sensor is applicable to the vibration monitoring of large-scale hydro generator units and low-speed rotating machinery, as well as the long-term and periodic testing fields such as machine tool accuracy testing, seismic monitoring geological exploration, structural vibration analysis, bridge, dam and subgrade vibration testing.

Main performance indexes:
