[?]: Smoothing analog inputs

Post by venix » Wed May 28, 2008 9:26 am

Hello dear friends!

I have a problem with 2 analog signals that came from 2 analog inputs.
The values that provides are dancing around a value.
This is not right for me because on a specified value i have two conditions that are enabling shuttle.

I serched in Siemens forum but with no use!

Best Regards!

input analogy stabiled?
what input this?4-20 0-5 pt100?
it`s security???? :evil: correct your post within information
dancing around a value
without this information my council for you - turn off music :D

I establish the input analogy.

I have 2 sensors.
One of them is a PT 100 wich is connected to an measuring amplifier that provides 0-10 V at output
and the other one is a pressure traductor wich is connected at another measuring amplifier wich also is providing 0 - 10 V at output.
The pressure traductor is simulated by one current calibrator(4-20 mA).

I measured with a multimeter the output from the measuring amplifiers,
the value is constant but this is not so important because I see just the rms value.
A better solution is to use an oscilloscope but now I don't have one

About the "dancing" (I turned the music off but with no result ) what I want to tell you is the that the value is fluctuating near a value.
