ACCORDING TO PUBLISHED SPECS, THE ACCUMEASURE 500 RACK INDIVIDUALLY CAN ACCEPT PROBES WITH RANGES UP TO 15 MILLIMETERS COMPARED TO MICROSENSE 4810 3U EUROCARD FOR RACK MOUNTING WHICH ONLY ACCEPTS PROBES UP TO JUST 1.5 MILLIMETERS. ALTHOUGH THE MICROSENSE HAS BETTER RESOLUTION IT TRADES OFF LINEARITY (10X WORSE THAN MTI AS 500 RACK) FOR RESOLUTION.
According to published specs, the Accumeasure 500 capacitance displacement sensor rack’s individual Amplifiers can accept probes with ranges up to 15 millimeters compared to Microsense 4810 3U Eurocard for rack mounting which only accepts probes up to just +/- 2mm.
