The aim of the course is that the student, through concrete examples and work with sensors and complete measuring chains, adopts and masters the basic concepts of measuring non-electrical quantities in mechanical engineering using computer technology and gaining practical experience in virtual instrumentation (measuring instruments based on computers) and digital data acquisition.

Upon successful completion of this course, the student should be able to: ● Assemble and apply electrical measuring chains to measure a wide range of physical quantities (temperature, pressure, force, torque, flow, position, speed, acceleration, vibration, ..) ● Select the appropriate components and assemble a computer-based measuring system through the concept of virtual instruments. ● Uses LabVIEW graphical development environment to create simple measurement applications ● Develops and implements computer-based measurement systems for a variety of industrial measurements.

1. Introduction to measurement techniques; 2. Measurement of non-electrical quantities in mechanical engineering (General information on sensors, sensors of position, speed, acceleration, force, torque, pressure, mass, temperature, flow, associated signal conditioning systems); 3. Digital measurement techniques (time domain and signal discretization, required sampling rate, quantization, A/D and D/A conversion, digital counters, filtering); 4. Architecture and basic principles of operation of computers for data acquisition (DAQS);

Introduction to Virtual Instrumentation (VI) and Labview Programming Environment; Data flow in VI; Troubleshooting and debugging of virtual instruments; Implementation of virtual instruments; File writing and reading techniques; File formats; Development of modular applications, Labview programming techniques; Use of Acquisition Hardware Resources in Labview; Introduction to sensors and complete measuring chains through practical examples and tasks;
