Design of indirect sensing of gas valve throttle position
Burian, Jaroslav ; Jankovský, Jaroslav (referee) ; Otáhal, Alexandr (advisor)
This thesis deals with the design of a circuit for measuring the throttle position of the PX52 valve from Resideo. The theoretical part discusses the methods whose principle can be used to determine the position of the throttle valve controlled by a stepper motor. Subsequently, the communication protocols that can be chosen between in the design are described. Methods for measuring the mutual properties of the coils were also described. In the practical part, a PCB was created to verify both methods. Furthermore, a program for testing both methods is described in the paper. These methods are compared with each other for different coil variants. Finally, the method is selected and the program is modified for the measurements.

Analytical workplace for gas valves
Skočík, Pavel ; Havránek, Zdeněk (referee) ; Klusáček, Stanislav (advisor)
This work deals with the measurement of parameters of different types of gas control valves, of a assembling measuring workplace and development of a program for a complex control system consisting of the Siemens acquisition boards and software resources LabVIEW. The program stores the values of inlet and outlet pressure, flow, time or modulation current into a text file. The timing and number of samples can be changed. Outlet pressure versus time or modulation current is displayed on the monitor chart.

Production of gas valves on the automatic line
Pešl, Milan ; Rumíšek, Pavel (referee) ; Štroner, Marek (advisor)
This thesis deals with the evaluation of manufacturing gas valves on the automatic line and the design of CCTV systems to detect errors at assembly in Honeywell Czech Republic Ltd. The aim of this thesis is mutual comparison of the respective proposed options of the camera system, their optimal selection, and the evaluation of detected errors of the line by using Pareto Charts. An integral part of this work is a brief description of the automatic line for gas valves and the history of Honeywell Company.
