Hi Nicola,
First you have to have in mind that FieldPoint is a line of distributed I/O modules, a I/O module is not a sensor, but a device that acquires a signal from a sensor.
Having that in mind the FieldPoint I/O module to be used will depend on the sensor that you choose to measure vibration. There are several sensors to measure vibration and therefore they vary on the type of output signal they provide. Some accelerometers will provide a "duty-cycle output signal" as you can see in the following page :
http://webs.cs.berkeley.edu/tos/hardware/design/data_sheets/adxl202lcc.pdf
Some other accelerometers will provide voltage or even current as an output, so really the FieldPoint I/O module that you will choose will depend on which type of sen
sor you use.
The modules that I believe will match some of the sensors in the market for vibration include :
[c]FP-AI-110, [c]FP-AI-111, [c]FP-AI-100 for analog output sensors.
[c]FP-CTR-50x for frequency output sensors...
However have in mind that even if you find a frequency output sensor for vibration, you still have to check if the sensor matches the [c]FP-CTR-50x as far as two important factors :
- Sinking or sourcing
- Threshold
I hope it helps
Best Regards
Andre Oliveira
