RePreS - Redundant pressure monitoring for safety-critical applications
The R&D project involves the development of particularly fail-safe pressure sensors, which are monitored by a connected logic.
This project is funded by the European Regional Development Fund (ERDF).
problem
In many applications, the pressure in liquids and gases is monitored to control the process, but also for personal and plant safety. For this purpose, simple mechanical pressure switches up to complex pressure control systems are currently installed. In order to make machine and systems even more energy-efficient and cost-optimized, there is a need for highly integrated and easily and precisely adjustable devices. In order to meet these requirements, new sensor technologies for use will be tested and created together with an industrial partner.
objective
The basis of the development is given by the use of novel, highly sensitive sensor thin films, which can convert a mechanical strain highly sensitive into a pressure-proportional electrical signal. Pressure ranges up to 500 bar for must be covered. The new pressure sensor solutions are complemented by an adapted electronics and software development. The cooperation project is intended to lay the foundation for the development of modular pressure measuring systems.
approach
Commercially available pressure sensors are usually offered by manufacturers complete with integrated electronics, which on the one hand compensates for temperature-related errors and on the other hand provides a standardized output signal (0 ... 10 V or 4 ... 20 mA). They are also usually equipped with their own housing and an electric plug. As a result, they build quite large and cannot be integrated as desired.
The research and development of thin highly sensitive sensor layers by the research group Sensors and Thin Film Technology at HTW saar and ZeMA offers the opportunity to develop a suitable solution. As a starting point for the implementation, the cooperation partners see the highly sensitive sensor layers based on NiCr and carbon, which have been researched in recent years by the research group Sensors and Thin Film Technology.
