IEPE vibration sensor synchronous signal acquisition card /icp synchronous data network acquisition module

One 、ICP Is a built-in microelectronic amplifier recognition PCB Terminology of piezoelectric sensors .(ICP yes PCB Group,Inc. The registered trademark of ) It is powered by the constant current signal conditioner , The result is easy to operate , Low impedance two-wire system , Pictured 5 Shown .

 

Besides being easy to use and simple to operate ,ICP The sensor also has many advantages over the traditional charge output sensor , Include ：

1) Fixed voltage sensitivity , It has nothing to do with cable length or capacitance .

2.) Low output impedance (<100 ohm ) Allow signals to be transmitted through long cables through harsh environments , Almost no loss of signal quality .

3.) The two-wire system can accommodate standard low-cost coaxial cables or other two conductor cables .

4.) High-quality , The voltage output is compatible with the standard reading , Recording or collecting instruments .

5.) The intrinsic sensor self-test function is realized by monitoring the output bias voltage of the sensor .

6.) Low cost per channel , Because the sensor only needs a low-cost constant current signal regulator .

7.) Reduce system maintenance .

8.) Direction operation of readout and data acquisition instruments , It contains information for PCB Of ICP The power supply of the sensor .
