Controladores e Indicadores de Processo Single Loop
Os instrumentos de controle empregados na indústria de processos (química, siderúrgica, papel etc.) têm sua própria terminologia. Os termos utilizados definem as características próprias de medida e controle dos diversos instrumentos: indicadores, registradores, controladores, transmissores e válvulas de controle. A terminologia empregada é unificada entre os fabricantes, os usuários e os organismos que intervêm direta ou indiretamente no campo da instrumentação industrial.

Modbus TCP and its Client-Server model and MQTT and its Publish-Subscribe model
The Modbus TCP protocol has been used for years in automation applications. However, with the advent of concepts such as Industry 4.0, IoT and wireless devices, new necessities - that make difficult to use the Client-Server model – have arrived. What are the possible alternatives? Written by our Project Coordinator Fabio Coelho de Souza, this article brings us some ideas.

The HART Communication Protocol
Communication with machinery and control and measuring instruments is the basis of industrial automation. The simplest, most robust and oldest communication technique implemented is a current loop with a normal range of 4 mA to 20 mA. However, the obvious disadvantage is that a single loop allows only one-way communication from a sensor to an actuator. Developed in the mid-1980s, the HART ™ (Highway Addressable Remote Transducer) protocol allows two-way communication of additional information - in addition to the normal process variables - between intelligent field devices.

Approval of calibration certificates and Permissible Error Limits - a process approach
It is not uncommon to find in the Quality or the Instrumentation environment those who are concerned with the calibration certificate or with a calibration certificate that is expiring on a certain date, always focusing on to be approved on some evaluation or audit. But does the calibration certificate alone guarantee the reliability of the process?

Efficient and secure industrial remote access using AirGate-3G router and VPN infrastructure
Remote access to electronics and machines around the globe is gaining importance quickly - both in industry and other areas related to it. Experts point out that remote control and monitoring are some of the most important mechanisms for increasing productivity and reducing costs, raising the interest of companies to implement them. The need for information about industrial machines is of the utmost importance so that company managers can become aware of the current scenario of their factory and take action quickly. The ability to use the Internet to access the installed machines greatly reduces maintenance costs, optimizing the monitoring processes and eliminating the need for large displacements to verify problems, allowing control of remote industrial plants without any frontiers.

Remote Monitoring in Photovoltaic Solar Generation
A photovoltaic solar generation facility is intended to generate electric power from photovoltaic cells. The correct design sizing shall assure the supply of 100% of the power demanded by the installation where the plant will be implemented, so that the electricity bill of the prosumer (consumer-generator) is reduced next to zero, allowing maximum return on the investment. To achieve this goal, limitations such as the physical space and climate conditions need to be observed to assure maximum efficiency of the application.

Temperature measurement applications using temperature transmitters
Temperature is one of the most common parameters measured across the industry. It is essential to measure, control and monitor temperature to ensure quality, safety and correct operation on various processes. Different variables have to be considered when developing a temperature measurement system such as non-linearity, accuracy and stability to ensure a reliable temperature measurement. Variables like maintenance and wiring costs must be taken into account to make the system as cost-effective as possible.
