This paper describes the design, implementation and test results of a battery-operated wireless airflow sensor for use in mining applications. The sensor uses ultrasonic transducers for flow estimation and the ISA100 standard for wireless communication. The work demonstrates the feasibility of the s...

Denne rapporten beskriver resultatene som er oppnådd i SUP prosjektet. Tekniske utførelse har vært gjort av SINTEF Digital, mens Enfo har bidratt med systemdesign, integrasjon og test. Prosjektet har levert et ferdig utviklet frekvensrele som er testet og CE-godkjent av Nemko. Det er klart for komme...

This report investigates the technological basis for low power, low bitrate, medium range, wireless transmission of environmental sensor data. This is a typical 'Internet of Things' (IoT) application, and most of our findings are therefore generally applicable to the wider IoT field. The report star...

SAMMENDRAG: Økt digitalisering, automatisering og elektrifisering Fremtidens transportsektor vil kjennetegnes av økt digitalisering, automatisering og elektrifisering. I denne rapporten redegjør vi for generelle teknologitrender og teknologitrender som er forventet å ha spesifikk betydning for t...

Wireless communication is an important part of everyday life, but has until recently been considered too unreliable for use in industrial processes. In particular, there has been reluctance to accept wireless systems as part of safety critical operations. This report considers the pros and cons of w...

Approximately 70% of South African mines are classified as fiery, where methane gas potentially could cause explosions. The number of flammable gas reports and accidents are increasing steadily for both gold and platinum mines. However, there is less awareness of the hazards of methane in hard rock ...

Wireless communication is already used in process automation for process monitoring. The next stage of implementation of wireless technology in industrial applications is for process control. The need for wireless networked control systems has evolved because of the necessity for extensibility, mobi...
