Gefran's wide range of sensors offer the ability to measure the primary process variables: position, pressure, force, temperature and humidity.
For example, the product portfolio for Melt pressure measurements includes:
• mercury filled sensors for measurements up to 400°C
• oil filled sensors (FDA approved) for measurements up to 315°C
• NAK filled sensors (GRAS) for measurements up to 540°C
• non filled sensors (IMPACT series) for measurements up to 350°C
In particular the IN and IE Melt pressure series is:
• robust
• reliable
• modular
• suitable for static and dynamic pressure
Moreover, the TR load cell family is specifically designed for plastic films tension control and a wide range of temperature sensors provides an accurate measurements for the control loop.
The Gefran SieiDrive family is a wide range of Inverters and Servo drives, designed to control with high performances the asynchronous and synchronous motors applied in high end automation processes.
The enhanced features and flexibility of the "ADV200" AC Drive family, make suitable in several parts of the machines as: screw control, dosers, winders and cutters.
• power range from 0.75kW up to 1.5MW
• AC mains supply 3ph 400Vac...690Vac
• Filed Oriented Control in open/closed loop
Main features:
• communication via Modbus, Profibus, GDNet, CANopen and DeviceNet
• integrated PLC under standard IEC 61131-3 (5 programming languages)
• Configuration tool integrating a software oscilloscope with synchronous sampling (buffered) at 250µsec for an easy commissioning
