There are a couple of values that you will need to look up that are specific to the particular sensor that you bought. These are the "a" and "b" values in the manual, but are typically called alpha and beta by the manufacturer. Most of the PT100's that I looked at were typically linear with respect to the temperature (ie; beta =0). There is an Omega catalogue from Dr. that I used to order the PT100 that I was using. I will drop this off in the control's room. I've marked the page of the sensor that I ordered (1PT100K2515, Class B Tolerance) and the page with its specifications (for what it's worth, it may be helpful to see what to look for using your sensor). Since I only had a small number of the PT1000 sensors left; I could only give you 15. I confirm that, the way the adapters are made for the ELMB, those sensors connect with 4-wire are supposed to be Pt100, the ones connected with 2-wire Pt1000. The way the ELMBs are now equipped is that on each 34pin 3M connector the 1st 4 channels are for 2 4-wire sensors, the other 12 channels for 2-wire sensors. You will use 6 connectors (=14 sensors) on each side (1 per SM), leaving 2 spare connectors per side. In this configuration you would need for all EMC 24 4-wire sensors (=Pt100) and 144 2-wire sensors (=Pt1000) http://lhcb-vd.web.cern.ch/lhcb-vd/ECS/ElmbUserGuide.pdf Manual that Robbie had mentioned: http://atlas.web.cern.ch/Atlas/GROUPS/DAQTRIG/DCS/ELMB/DIST/ElmbUserGuide.pdf Good list of sources according to Lionel: http://atlas.web.cern.ch/Atlas/GROUPS/DAQTRIG/DCS/ELMB/DIST/ELMBdoc.html some other weblinks that may be of some importance. http://www.maxim-ic.com/appnotes.cfm/appnote_number/345 http://www.uoguelph.ca/!antoon/gadgets/sccs.htm http://en.wikipedia.org/wiki/Bridge_circuit
