The digital vibration check meter can measure vibration speed, acceleration and displacement. It has an acceleration measurement range of 0.1~199.9m/s2 peak. The vibration tester uses a piezoelectric accelerometer to convert the vibration signal into an electrical signal and analyze the input signal.

Q1: What is a vibration meter?
A1: Vibration meter is used to directly indicate the peak, peak-to-peak, mean value or root mean square value of vibration quantity such as displacement, velocity, acceleration and derivative of acceleration. The main parts of this vibration tester are integral differential circuit, amplifier circuit, voltage detector and meter head. The integral and differential circuit is used to complete the integral and differential operation between the above vibration quantities. Generally, the integral and differential operational amplifier can be used, and the low-pass filter and high-pass filter can be used respectively to complete the integral and differential operation. However, attention should be paid to their application frequency range when using such instruments for calculation. The vibration meter allows one to obtain only the total intensity of the vibration (the vibration level) and no other information.
Q2: How does a vibration meter work?
A2: Mechanical vibration is generally measured by electrical measurement. The basic principle of vibration meter is to convert mechanical quantity into electric quantity through vibration sensor, and then measure and analyze the electric quantity, so as to obtain various parameter values of the measured mechanical vibration quantity. In the field vibration test of turbine generator set, the vibration sensor commonly used in vibration tester has three types, they are eddy current non-contact displacement sensor to measure the relative vibration of rotating shaft, inertia speed sensor and voltage acceleration sensor to measure the vibration of bearing seat and foundation, cylinder structure and so on. In addition, in order to measure the absolute vibration of a rotating shaft, a composite sensor consisting of an eddy current non-contact displacement sensor and an inertial velocity sensor is often used.
Q3: What does a vibration meter do?
A3: The vibration meter can easily measure the vibration parameters such as vibration, acceleration and velocity. The vibration tester can also be used to reliably and quantitatively evaluate the vibrations of rotating and reciprocating machines. It is widely used in mechanical design and manufacture, military, electric power, equipment management, transportation and environmental protection departments etc. The vibration meter provides these fields great convenience for on-line inspection and monitoring of machine equipment faults and aging signals, product quality control, vibration test measurement and vibration control.
Tips for using portable vibration meter
- Don't dismantle the casing of the vibration meter.
- Don't use the handheld vibration meter in an environment with explosive gas, steam and damp environment.
- When the measurement is carried out near the rotating part of the machine, operate carefully to avoid being pulled into the machine.
- Please use a dry cloth to wipe the instrument case at the time of cleaning. Don't use corrosive detergents.
- Please take out the battery if the portable vibration meter is not in use for a long time or the storage temperature is higher than 50℃ to avoid corrosion to the vibration tester due to battery leakage.
