Vibration measurer
Mechanical failure stethoscope MS-120
Specification and model：MS-120
Product application：it is mainly used in engine and other machinery. It can quickly detect the mechanical noise from diesel engine, cylinder and automobile, and accurately find out the location of mechanical fault.
*Through the sensitive piezoelectric vibration sensor, it can receive weak audio signal and amplify the signal according to the need, and judge whether the signal is in the normal audio range and its direction.
*The purpose of the design is to quickly measure the sound and noise beyond the tolerance range with low cost.
*It can quickly measure the following mechanical noise, such as piston, worn gear and bearing, damaged valve, faulty water pump, gasket and so on. At the same time, it can also track and locate the noise on the automobile instrument.
