Low Acoustic Noise Vibration Test Machine Small Shaker for
University
Introduction:
ET series standard vibration table with light weight, small volume,
convenient to move, is widely used in the acceleration sensor
calibration, the tiny parts of resistance to vibration test,
fatigue test and mechanical impedance test. At the same time, the
ET series can also be used for teaching and scientific research and
laboratory.
Vibration test is widely applied in many fields, ranging from
circuit board, airplane, ship, rocket, missile, automobile,
household appliance and other industrial products.
Labtone can offer you the whole vibration and testing proposal, and
provide you with the quality certificates of products according to
national and international standards, including GB, GJB, UL, JIS,
DIN, ISO, BS, MIL, IEC and ASTM standards.

Introduction to vibration controller
The vibration controller is of advanced distribution structure
system, and closed-loop control is achieved by DSP processor. PC is
independent of control loop to ensure real-time and high efficiency
of the control system so as to timely and rapidly respond to any
changes of the test system, and ensure control stability and high
precision. 32-bit floating-point DSP processor with primary
frequency up to 300MHz and 24-bit resolution ADC/DAC are used for
hardware in coordination with high precision floating-point digital
filtering and low noise design technology of hardware circuit. The
dynamic random control range of the controller is more than 90dB
and the signal to noise ratio is more than 100dB.
