The TR 3-roller tension meter, designed for wires and strips, is made of alloy steel and features IP65-rated dustproof and waterproof protection. It supports a measuring capacity ranging from 0.1 kg to 50 kg.

It adopts a 3-roller structure, with selectable roller materials such as hard-anodized aluminum alloy, chrome-plated alloy steel, plastic, or ceramic, providing high measurement accuracy. The compact design allows easy installation and offers excellent stability. It outputs a linear voltage signal of 1.5 mV/V, which can be connected to a transmitter for 0–10 V or 4–20 mA output. The sensor is suitable for various optical fibers, yarns, and chemical fibers. Ideal for tension measurement, it is widely used in electronics, chemical, textile, paper, machinery, and industrial automation measurement and control applications.
