Working principles, characteristics and symbols of sensors: limit switches, reed contacts, proximity sensors with the discrete output (inductive, capacitive, and photoelectric), the discrete pressure sensor. Relay types, construction, operation method, and work objectives. Delay relays.
Functional control and contact schemes. Implementation of the relay control in the pneumatic automation: depending on positions, delay, pressure requirements and different logical conditions.

Provide knowledge about the production of the compressed air, productivity management of compressors, compressed air distribution and preparation, pneumatic actuators, determination of the dimensions of pneumatic cylinders and about pneumatic and pneumatic control components used in the standard plan.

The graduate is familiar with the classification and structure of pneumatic systems, the properties of air, production requirements for of the compressed air, construction and operation principles of pneumatic components and the description of the control process.
The graduate is able to compile control projects, pneumatic and electrical diagrams, select needed components, install them and follow safety requirements.

Lectures, tests, practical works.

The course ends with the final account. Positively executed test and the practical work are the prerequisites of the accounting. Test consists written questions within the framework of the lecture material. The final grade will turn out from the average grades of the test and the practical work.
