He suggested a cap, you went further and suggested R-C filter.
That might have been productive and interesting to read. No copy 
in your sent-folder?

So if I ask a favour I cant question the suggestions?

Aluminium housing.

>If your spec is "no" noise,

With none, I meant not so much noise that the signal itself 
drowns in it 200-fold. Less than 5mV noise is ok, and can be suppressed
to even lower levels. Perhaps with a cap or an R-C filter... =)

For now I have another solution in place. Talked to the sales rep. today and
they are looking into it. He said the noise nor jumps is normal by any means

and will get back to me after he has talked to the manufacturer.
