Vishay Systems G4 Process Control Instruments Feature Synchronized Sampling, Up to 800 Updates Per Second, and Integrated, Flexible Digital I/O
G4 Has Four Base Mounting Options: DIN Rail, Panel, Desktop, and Harsh-Environment
MALVERN, PENNSYLVANIA September 13, 2006 Vishay Intertechnology, Inc. (NYSE:VSH) announces the introduction of the Vishay Systems G4 family of advanced process control instruments. 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. The G4 modular structure enables the user to tailor its performance according to the application, and is available in four versions DIN rail, panel, desktop, and harsh-environment providing easy installation in any type of environment. All units support high update rate (up to 800 updates per second), high sample rate (up to 20 kHz), synchronized multiple measurement channels (up to eight), true vector calculation, integrated digital inputs and outputs, and modern user interface.
The G4 is compatible with a wide variety of industrial communication interfaces: Profibus, DeviceNet, Modbus TCP, Ethernet, USB, RS485, and RS232. Software upgrades can be downloaded from the web or can be transferred to G4 units via a standard USB port connection. Custom software designed to customer requirements is available upon request. All versions meet CE (industrial), UL and OIML requirements. Detailed specifications for model G4-RM (DIN-rail mount) can be found at www.vishay.com/doc?12208. Detailed specifications for models G4-PM (panel mount), G4-DT (desktop), and G4-HE (harsh-environment enclosure) can be found at www.vishay.com/doc?12207.
Model G4-RM (DIN-Rail Mount)
The G4-RM (DIN-Rail Mount) model has up to six weighing / force measurement channels per unit. G4-RM instruments accommodate up to three different, easily installed modules for advanced performance, additional functional channels, custom applications, or repair. This provides customers with a highly flexible, upgradeable, single instrument system capable of weighing up to six independent vessels or scales. For web tension applications, up to six zones (rolls) can be monitored simultaneously. The unit is controlled via the local service and control panel. The display is 2 x 16 character LCD with backlighting, and the keyboard has four membrane keys.
Models G4-PM (Panel Mount), G4-DT (Desktop), G4-HE (Harsh-Environment Enclosure)
The G4-PM (panel mount), G4-DT (desktop), and G4-HE (harsh-environment enclosure) models have up to eight weighing / force measurement channels per unit. Features include graphic user interface (color LCD display with backlight), and data entry through a touch screen and / or functional keypad. G4-PM, G4-DT, and G4-HE instruments accommodate up to seven different, easily installed modules for advanced performance, additional functional channels, custom applications, or repair. This provides customers with a highly flexible, upgradeable, single instrument system capable of weighing up to eight independent vessels or scales.
A 5.7-inch color touch screen facilitates operation and simplifies parameter changes. The screen displays up to four weighing / force channels simultaneously, allowing the user full control of multiple process vessels. The screen provides good visibility of the process and easy navigation through parameter menus and settings.
The G4-PM and G4-DT have an aluminum housing and plastic panel. The G4-HE has a stainless steel housing and plastic panel. All versions meet the environmental conditions of the food, pharmaceutical, and chemical industry. The display is color TFT LCD with backlighting, and the keyboard has 34 membrane keys. Units can be configured for either 24-volt DC or 115 / 230-volt AC operation. The units are rated IP65, and have CE (Industrial) and OIML certifications.
