Invensys Eurotherm is launching the piccolo P304i Melt Pressure Indicator and P304c Controller. Monitoring and control of the pressure in plastics manufacture leads to higher-quality end product with lower scrap, and can prevent damage to machinery caused by overpressure conditions. This addition to Eurotherm's range of products offers versatile options with advanced features and a wide range of hardware options that make them suitable for all types of plastic processing.
This new, innovative Melt Pressure Indicator and Controller is suitable for extrusion and injection moulding in plastics processing, as Tim Linnell, Product Portfolio Manager at Invensys Eurotherm explains: "Compatible with industry standard probes and strain gauges including Dynisco, the P304 uses automatic standard shunt calibration procedures making it ideal for new installations and retrofit. It has been designed to monitor and automate the pressure of molten plastic being forced through a die or into a mould. Usually a screen is used to filter out impurities, and as these build up on the screen, the pressure needed to push plastic through increases. If not carefully monitored and controlled, this pressure can cause damage to equipment.
"P304 combines the most advanced features for management of melt pressure of any instrument in its class with simplicity of use and a high-speed 50ms cycle time so that rapid changes in pressure can be monitored and dealt with."
Key features aimed at improving operational efficiency include:
The P304 is the latest from Eurotherm's piccolo range which has been designed for plastics and small furnace applications and provides advanced precision PID control in an easy-to-use and cost-effective format. Plastics extrusion applications benefit from specialised algorithms designed to optimise use of water, fan or oil cooling, and the fast-reacting overshoot-free control assures continuous high-quality production without waste. The units are quick to commission and apply with industry standard connections to sensors and actuators and a quick code-guided configuration.
Tim concludes: "Continuing a thread of Eurotherm product innovation that spans 50 years, 2014 will see an ambitious product release schedule. Our philosophy is to package advanced control and automation algorithms in cost effective ways so that our industrial customers benefit from the latest advances but with products that are easy to use and apply."
