Interface Model 9840-400 4-Channel Intelligent Digital Indicator

TheInterface Model 9840-400 4-Channel Intelligent  Digital Indicator represents an elite, calibration-grade indicator engineered to manage four independent strain gauge force vectors concurrently. Designed as the multi-channel evolution of the industry-standard 9840 platform, this instrument brings remarkable internal resolution and reference stability to advanced testing environments. It is highly utilised across the UK for aerospace validation rigs, commercial metrology laboratories, and in-house safety calibration departments where multi-sensor comparison checks require absolute timing synchronicity.

The hardware architecture centres around two interactive 7-inch graphical touch screen displays, providing operators with sharp, simultaneous side-by-side data visualisation across all active ports. A premier mechanical advantage of this 4-channel layout is its capability to handle complex structural cross-compensation; it allows an engineer to monitor a primary vertical force, alongside a secondary redundant reference bridge while concurrently tracking background moments to fully control side-load errors. Fully compliant with IEEE 1451.4 TEDS plug-and-play standards, the 9840-400 reads and applies sensor calibration matrices automatically, dropping system configuration times to mere seconds while maintaining an exceptional non-linearity specification of < ±0.005% Full Scale.
