Meteorological Station with Remote Access
Svoboda, Josef ; Číž, Radim (referee) ; Sysel, Petr (advisor)
This thesis discusses design and realization of air temperature, pressure and relative humidity measuring device, transmission of measured data over internet and their presentation on a web site. First chapter introduces reader into principles of measuring air temperature, pressure and relative humidity and various types of sensors used for measuring . Next, the conception of designed system is described. Designed system must accomplish tasks from reading raw data from the sensor up to thein graphical presentation to the internet user. Second and third chapter describes hardware and software design of air temperature, pressure and relative humidity measuring unit. In next part one can find description of software used to transmit measured data over internet and software for generating web pages which are shown to users. The work is revieved in the final part of this thesis.

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.

IO/Link interface implementation to pressure sensors
Pešl, Jiří ; Novotný, Radovan (referee) ; Kadlec, Jaroslav (advisor)
This thesis is concerned with the measurement of physical quantities. Thesis describes sensors in general terms and requirements, which delivers latest trends in the field of automation. The main theme of this thesis is sensors for meassuring pressure, and their connection to the automation chain. In the next part thesis describes the design of the converter for connecting SMART sensors for pressure measuring, that use HART communication protocol, to the automation systems managed by a communication protocol IO-link. First will be described in detail various communication standards by their ISO OSI model, and on this theoretical basis will be based design of converter between communication protocol HART and communication protocol IO-Link. The last part will be Designed software for this converter.

Oscillometric blood pressure measurement
Brabencová, Klára ; Harabiš, Vratislav (referee) ; Slávik, Vladimír (advisor)
The aim of my work is to propose a meter of blood pressure with oscillometric method using LabView software. To determine systolic and diastolic blood pressure is used detect the maximum oscillation of the envelope signal. The maximum oscillation corresponding to a mean arterial pressure and this value is then calculate systolic and diastolic pressure. In the programming environment of LabVIEW is the signal from the pressure sensor and cuff over the LabPro processed and are calculated limits of arterial pressure.

Analysis of intracranial pressure
Procházka, Ondřej ; Kolářová, Jana (referee) ; Kozumplík, Jiří (advisor)
The aim of my bachelor’s work is the literature review about problematic of measurement and evaluation of intracranial pressure. I describe physical principle of intracranial pressure, anatomy of cerebral ventricle and different accesses and placement of measuring instruments in intracranial place. Moreover I describe evaluation of clinical data at standard way and explain analysis in frequency and time domain by program MATLAB. I make a script for analysis ICP data. It calculates main ICP, amplitude and latency of waves, RAP index and shows spectrum of amplitude.

Integration of flow and pressure sensors into the compressed air plant subsystem
Rýznar, Jan ; Baštán, Ondřej (referee) ; Fiedler, Petr (advisor)
The work deals with the design of the project solution 1007 - Měření průtoku vzduchu. The subject of the project is the integration of flow and pressure sensors on compressed air distribution in the paper industry. The solution uses decentralized peripherals together with a programmable logic controller communicating with each other via the Profinet network. Operating software for programmable logic controller and decentralized peripherals and HMI panel is parth of the project. As well as drawing documentation including solutions for powering individual components.

Pressure Sensing Using Ltcc Technology
Somer, Jakub
This paper deal with the design, manufacturing and measurement of optical pressure sensors produced using Low Temperature Co-fired Ceramic technology. There is brief overview of measurement methods used for pressure sensor interrogation. Benefits and problems regarding measurement methods are discussed. Pressure transducers are based on the change of the light spectrum reflected from the Fiber Bragg Grating integrated in the sensor. Low Temperature Co-fired Ceramic structure with membrane was used for the forming of a pressure transducer. Samples of fiber optic sensors are calibrated using reference pressure measurement and characteristics of the sensors are measured. Pressure sensors for different pressure ranges were measured and tested.
