Capacitive sensors
Elite series non-contact sensors measure very small displacements of conductive materials with high resolution in precise positioning applications.
Features & benefits
-
0.01 to 10 mm measuring ranges; 1 nm resolution
-
CPL190 and CPL290 capacitive sensors and MM190 meter/signal processing module
-
Differential analog signals to data acquisition system for high signal to noise ratio
-
Odd and even-numbered channels use inverted excitation signals to null ground current flow and eliminate noise and offset in differential measurements
