Working Principle:
This transducer acts as an intelligent signal conditioner. It excites the connected load cell, reads the minute resistance changes caused by mechanical strain, and converts this to a proportional voltage. Internal microprocessors apply calibration constants and temperature compensation before outputting a highly accurate, noise-free tension signal to the control system.
Installation Requirements:
- Mounting Orientation: Install in a location protected from direct mechanical impact and excessive ambient heat.
- Cable Routing: Keep signal cables separated from motor drive cables and high-voltage power lines.
- Configuration: Set DIP switches or software parameters to match the connected load cell sensitivity and desired output range.
Usage Precautions:
- Order Code Verification: Always verify the complete order code (3BSE050090R20) when replacing a unit to ensure parameter compatibility.
- Load Cell Matching: Ensure the connected load cell impedance and sensitivity match the transducer’s input specifications.
- Safety: Disconnect power before making any wiring changes to prevent short circuits.
