Tension amplifiers are electronic devices designed to process and amplify signals from tension sensors with high accuracy and stability. They enhance weak sensor outputs, provide intelligent adjustments such as zero calibration and gain control, and deliver standardized signals (e.g., 0–10V) for easy integration with PLCs, controllers, or display instruments. Widely used in web guiding, printing, packaging, and other tension control systems, tension amplifiers ensure precise, reliable monitoring and control of material tension in industrial processes.
