The experimental measurement systems arevery useful in engineering education because the studentscan use and verify their previous knowledge aboutsensors and transducers, signal conditioning and dataprocessing. This paper presents two electronicmeasurement systems which enable the computerizedstudy of the optical encoder and force sensor, respectively.The first sensor studying procedure performs theunderstanding and checking of the rotary incrementalencoder working modes and methods for resolutionimprovement, displacement and velocity measurement,and motion sense discrimination. The second sensorstudying procedure supposes the assignation of themeasurement points, plotting the transfer characteristicand computing some parameters (zero error, differentialsensitivity, relative sensitivity) of the strain gaugetransducer; the measured mass of the tested object canalso be displayed. Each electronic measurement systemcontains signal conditioning circuits, data acquisitionboard (organized around a microcontroller) and an IBMPCcompatible computer; the data acquisition board isserial connected to computer. A friendly user interfaceenables each computerized sensor study. The paper alsoincludes many experimental results. |
