Description
Key Features
- Directly connect to the strain gauge transducer (bridge voltage: DC only)
- Isolated 2 channel input
- Max. rated voltage to ground: 30 V rms or 60 V DC
- High 16-bit A/D resolution
- Use in combination with the MEMORY HiCORDER series (MR6000, MR8847A, MR8827, etc.)
- Meet application demands in the civil engineering, bridge building and machine tool, and automotive design fields
Supports strain gauge type transducers
Measurement example:
A torque sensor (strain-gage-type transducer) is connected to the Strain Unit U8969 to measure torque.
FFT analysis is performed on the measured torque signal to analyze the frequency components.
