Opis:
One of the most frequently measured quantity is temperature, which is also one of the most important physical quantities. Temperature has influence on the almost all states and processes in the nature as well as in technique. A wide range of temperature sensors is currently available on the market. They use different measurement principles and exist in many designs. According to the location of the sensing element in the measured environment, they are divided into two main groups: contact and non-contact. Further, we can divide the temperature sensors according to the physical principle on which they work. The article deals with the analysis and comparison of selected Arduino-compatible contact temperature sensors. The temperature measurement of machine functional nodes and its diagnostics are part of maintenance and engineering diagnostics. At present, NC and CNC machine diagnostics are an important trend in machine condition monitoring and machine status prediction to maintain production quality. Machine status monitoring allows reducing of machine service costs as well as maintaining the high production quality.

Opis:
The theoretical aspects of a new type of piezo-resistive pressure sensors for environments with rapidly changing temperatures are presented. The idea is that the sensor has two identical diaphragms which have different coefficients of linear thermal expansion. Therefore, when measuring pressure in environments with variable temperature, the diaphragms will have different deflection. This difference can be used to make appropriate correction of the sensor output signal and, thus, to increase accuracy of measurement. Since physical principles of sensors operation enable fast correction of the output signal, the sensor can be used in environments with rapidly changing temperature, which is its essential advantage. The paper presents practical implementation of the proposed theoretical aspects and the results of testing the developed sensor.

Opis:
Environmental evaluation arises as an innovative procedure to carry out preventive conservation of Cultural Heritage items. Parameters contributing to the proper conservation of such items can be monitored and assessed. Chemical sensors with optical response synthesised by the sol-gel method are useful for a complete and accurate environmental evaluation. Physical-chemical mechanisms of decay and degradation of materials can be predicted from the sensors response, which will favour the decisions on the adequate procedures to avoid damage. Sol-gel sensors prepared and applied in the present work are reversible, reusable and regenerable. Their optical response provides a change of colour vs. the parameters to which they are sensitive. Both temperature and environmental acidity have been monitored in several selected chambers of the Palace Museum of Wilanów (Warsaw, Poland). The optical response of sensors was recorded by visible spectrophotometry from June 2010 to December 2010. The results inform on the environmental conservation conditions, both indoor and outdoor the Palace. Main innovation of the research carried out concerns the evaluation of the environmental acidity as an essential parameter to be taken into account for the proper conservation that can not be measured by conventional methods.

Opis:
An article herein considers the development of a fiber-optic sensor system, based on fiber Bragg gratings. Presently, fiber-optic sensors has become world-widely known amongst sensor technologies, used for monitoring engineering and construction structures. The work is linked with developing the system from fiber-optic sensors on the basis of fiber optic gratings, its characteristics, deformation behavior and temperature, acting at fiber Bragg grating by means of computer modeling. The research is focused at the analysis of characteristics and deformation and temperature behavior of fiber-optic Bragg sensor. Fiber-optic Bragg sensor with tilted grating is used for measuring deformation of the object, the strength of which is changed, dependent on the applied force, as well, for measuring and detecting any temperature deviations, influencing at fiber Bragg grating, which might bring to fire and accidents. In the research, simulation modeling there was made in the MATLAB (Simulink) software.

Opis:
Sensitive MEMS-based thermal flow sensors are the best choice for monitoring the patient’s respiration prompt diagnosis of breath disturbances. In this paper, open space micro-calorimetric flow sensors are investigated as precise monitoring tools. The differential energy balance equation, including convection and conduction terms, is derived for thermal analysis of the considered sensor. The temperature-dependent thermal conductivity of the thin silicon-oxide membrane layer is considered in the energy balance equation. The derived thermal non-linear differential equation is solved using a well-known analytical method, and a finite-element numerical solution is used for the confirmation. Results show that the presented analytical model offers a precise tool for evaluating these sensors. The effects of flow and thin membrane film parameters on thermo-resistive micro-calorimetric flow sensors’ performance and sensitivity are evaluated. The optimization has been performed at different flow velocities using a genetic algorithm method to determine the optimum configuration of the considered flow sensor. The geometrical parameters are selected as a decision variable in the optimization procedure. In the final step, using optimization results and curve-fitting, the expressions for the optimum decision variables have been derived. The sensor’s optimum configuration is achieved analytically based on flow velocity with the analytical terms for optimum decision variables.

Opis:
Przedmiotem pracy była analiza nowo wdrożonego systemu sterowania i wizualizacji w obiekcie szklarniowym o powierzchni 0,5 ha. W opisywanym obiekcie system sterowania oparty jest na sterownikach PLC firmy Siemens S-5 oraz S-7 (ang. Programmable Logic Controller). Każdy ze sterowników wyposażony jest w układy wejściowe i wyjściowe do podłączania standardowych, fizycznych sygnałów automatyki. Przejrzysta i ergonomiczna wizualizacja połączona z możliwością wprowadzania zmian w pracy urządzeń wykonawczych z poziomu operatorskiego oraz zdalne sterowanie poprzez łącza internetowe procesem produkcji jest obecnie jednym z elementów nowoczesnego zarządzania, opartego na optymalizacji kosztowej procesu.

Opis:
Purpose: of the article is to develop a digital portable gas temperature meter in the range of -50…+600°C. To measure the temperature of dusty gas flows in the air pollution sources with the least significant digit of the digital device 1°C. Design/methodology/approach: The microprocessor measuring unit, probe and software is proposed. It leads to build a high-precision temperature meter based on a thin film sensor HM220 type "pt100". Findings: The calculation of the electrical schematic diagram parameters for signal conditioning of the sensor relative to the input range of the analog-to-digital converter. The experimental measuring unit and the probe of the gas temperature meter are assembled. The principle of the gas temperature meter calibration with the help of a precision resistance box MSR-60M is considered. The experimental gas temperature meter has a total standard uncertainty determined by type B for a maximum value of the measurement range of 1.94°C. The error of the sensor "pt100" makes the largest contribution to the total standard uncertainty, so the error increases in proportion to the value of the measured temperature. Research limitations/implications: On the basis of the proposed design of gas temperature meter it is possible to construct devices with various lengths of probes. Practical implications: The proposed meter is designed for environmental laboratories that measure the velocity, flow and sampling of dust and gas emissions from sources of air pollution. Originality/value: The device design differs due to the use of thermostable wire made of constantan as extending conductors of the temperature sensor, which is included in the unbalanced Wheatstone bridge. This solution allows the use of unipolar power supply 3.3 V for both analog and digital part of the meter. Temperature meter based on a thin film resistance thermometer is characterized by relative ease of manufacture, low material consumption, cost and high reliability.
