BENETECH GT633B Handheld Motor Probe Vibration Tester 1. Vibration testing is an important means to achieve equipment status and fault diagnosis. The use of handheld vibration meters improves production safety, quality and efficiency. 2. This instrument uses a piezoelectric acceleration sensor to convert vibration signals into electrical signals. By processing and analyzing the input signal, it displays the acceleration, velocity and displacement value of the vibration. It is widely used in machinery manufacturing, electricity, metallurgy, automobiles and other fields. 3. Sensor: piezoelectric ceramic accelerometer (shear type) 4.
