The Premier Solution for Wireless Overhead Weighing and Process Control Applications

The MSI-9300 crane scale combines an integrated weight display with advanced wireless data processing capability providing versatile solutions in overhead industrial weighing applications. The MSI-9300 merges MSI’s advanced CellScale™ technology with world-renowned crane scale designs providing local and remote control capabilities along with connectivity with plant information systems.

This model features industrial-grade, shock-mounted electronics, watertight packaging with large ultra-bright displays readable at distances up to 50 feet (15m). Integrated CellScale technology offers the ability to effectively monitor and control single or multiple crane scales from multiple locations throughout plant operations. Wireless, real-time transmission of weight and product information can be processed through a system-configured network of CellScale components from distances up to 1000feet (300m) with standard antennas. Operating range can be further increased with optional antennas configured with other networked CellScale components.

Both fixed and handheld digital weight indicators are available in addition to RF modems for wireless connectivity with peripheral computers and scoreboards. Optional 802.11b/g Ethernet connectivity is also supported for adaptation and integration with existing plant information systems. 

The MSI-9300 is available in a standard range of capacities, up to 50 tons. Larger and application specific designs are available for capacities over 50 tons. Additional options and configurations are also available for mill and foundry over high temperature ladle installations.
