The purpose and objective of the RRI project is to develop a breakthrough product that enables “real time” measurement of pressure in tools and connection to diagnostic tools, and will allow the measurement of pressures in the range of 0-2 000 bar. At the same time, the advanced electronics of the sensor will also be developed within the framework of the project to enable operation at tool temperatures up to 150 °C and melt temperatures up to 400 °C. At the same time, the product will be highly modularly designed as a building block with integrated electronics, which enables the digitalisation of pressure measurement, and the possibility of using either wireless and/or wired communication with the control and control system of the machine. In this way, the product will be applied in the widest range of modern manufacturing technologies of light metal casting and plastic injection moulding.
