The Yokogawa 701270 is a two-channel strain input module (NDIS) engineered for high-precision strain gauge measurements within Yokogawa’s ScopeCorder data acquisition platform. It integrates with compatible NDIS bridge heads—such as the 701955 and 701956—to deliver accurate static and dynamic strain analysis across industrial and laboratory environments.

– Key Features
• Dual-channel configuration for simultaneous multi-point strain monitoring
• Electronic auto-balance reduces setup time and improves measurement stability
• Three selectable excitation voltages accommodate varied gauge impedance and sensitivity requirements
• 16-bit resolution provides granular data acquisition for transient and fatigue analysis
• Wide frequency response from 0.01 Hz to 200 kHz supports quasi-static and dynamic testing
• NDIS connector ensures compatibility with standardized instrumentation ecosystems
– Typical Applications
Strain measurement in materials testing, structural health monitoring, mechanical component evaluation, and load cell integration within high-speed data acquisition workflows.
– Compatibility & Integration
The 701270 module integrates directly into Yokogawa DL350, DL850 series, DL950, and SL1000 data acquisition systems. Operation requires a compatible NDIS bridge head (701955 or 701956) for signal conditioning and gauge excitation.
