U-507 Sonic belt tension meter: 
 Tension :0.01-99900N 
 Frequency range :10-5000Hz 
 1, through the analog signal processing, can be measured under different conditions, the vibration waveform, and can read out the waveform cycle, the number of frequencies by the processing cycle, the conversion value of the tension 
 2, the automatic removal of noise, noise interference 
 3, large-screen LCD, can display the tension value and frequency value, unit value and standard tension measurement, display unit mass, belt width, belt length, choose one of three display 
 4, the background lighting design, can use the site to determine whether the use of background light 
 5, the microphone sensitivity to low frequency increases, the measurement can be used for large-scale conveyor
