TheME2655Cisadigitalpaneldisplayorpanelmount.It ismainlyintendedforthemeasurement of signals and the conditioning of sensors in the context ofprocess controls. It can provide an analog output that can be used by anacquisitionsystemoraPLC,transmitinRS232andhasdigitalinputsandoutputs(TOR).TheME2655C isavailable inmultiplerangesadaptedtothedifferentelectricaland physical quantities (force, torque, weighing, pressure, displacement,inclination ...). The sensor's sensitivity and measuring range information aresufficientforquickcommissioning. 3.1Frontpanel
