MMF M72B3 信号调节器（3通道，1 m/s² - 10 ^ 7 m /s²，无显示，适配器）

The M72 Series Signal Conditioners are intended for connection of piezoelectric acceleration,

force or pressure transducers. The input is suitable for sensors with charge output as well as for
IEPE compatible transducers and microphones.
The M72 enables optimal adjustment of the sensor signal to existing measuring equipment or
PC-based data acquisition systems. The Signal Conditioners provide the following functions:
• Adaptation of the sensor signal and sensor supply
• Amplification
• High- and low-pass filtering (for example anti-aliasing filter)
• Integration of the sensor signal, for instance, to measure velocity or displacement.
The instruments all have a robust aluminum housing making them suitable for work in the laboratory
as well as under field conditions
