Overview
The Magpowr TSA Tension Sensor Amplifier is a compact, DIN rail-mounted load cell amplifier designed for precision tension measurement and control. The TSA converts input signals from full-bridge or half-bridge tension sensors into standard industrial output signals, providing real-time feedback for automated web tension applications. With selectable 0–10 VDC or 4–20 mADC outputs, the TSA integrates seamlessly with PLCs, drives, and control systems used in printing, converting, packaging, and material handling.
Key Features
- Dual output formats: 0–10 VDC or 4–20 mADC for flexible integration
- 8:1 gain control range for adaptable sensor calibration
- 50% tare adjustment to zero out pre-tension or load offsets
- Internal excitation supply: 10 VDC or 5 VDC for both full-bridge and half-bridge sensors
- Minimal drift and excellent linearity for accurate tension control
- Compact DIN rail enclosure—fits restricted mounting spaces
- UL and CE approved for industrial compliance
