Vishay adds web interface to Model G4 weighing instruments
August 30, 2009 — Vishay Intertechnology announced that G4 advanced process control instruments have been enhanced to include remote access via web interface. This makes possible setup, maintenance, diagnostic tests, software updates, and other activities using a standard web browser.

The remote access feature enables plant maintenance engineers (or Vishay engineers, if allowed) to access G4 instruments anywhere in the world and set them up, monitor them, and run diagnostics tests. Weighing signals such as mV/V and actual weight can be monitored. This gives users an easy platform to operate, monitor, and maintain the instrument. Embedded security tools protect the system from erroneous or malicious access to ensure system and data integrity.

G4 instruments have four base mounting options: DIN rail, panel, desktop, and harsh environment. The G4-RM DIN rail mount model has up to six weighing/force measurement channels per unit. It is IP20-rated and operates with a power supply of 24 VDC. The G4-PM panel mount, G4-DT desktop, and G4-HE harsh environment models have up to eight weighing/force measurement channels per unit. They are IP65-rated and can be configured for either 24 VDC or 115/230 VAC operation.

All G4 models feature flexible configuration, synchronized sampling of all channels, a fast update rate of up to 800 updates per second, integrated and flexible digital I/O, easy parameter backup and restoration via USB port or internal memory, and communication via Ethernet, Profibus, DeviceNet, Modbus, USB, RS485, RS232, and Modbus/TCP.

Applications include process weighing and control, force measurement, web tension measurement and control, automation, force vector calculations, high dynamic force measurement, and high speed batching/blending systems.
