High precision ESMZL-2 10N 20N 50N micro tension sensor for textile yarn

The ESMZL-2 is a clamping-type micro tension sensor, specifically designed for monitoring the tension of ultra-fine wires. Its size is only comparable to a coin (Φ20~25mm × 30~40mm), and its compact design allows it to fit into various narrow installation spaces, offering a cost-performance ratio far superior to similar imported products. The sensor operates on the principle of resistive strain and achieves high-precision measurement through a Wheatstone bridge, with an accuracy of ±0.1%~±0.5%FS. It can accurately capture small tension fluctuations at the 0.1N level and is suitable for detecting fine wires with diameters ranging from 0.02mm to 2mm.

Its core advantage is its clamping, non-destructive installation, which requires no cutting of the wire and can be quickly fixed within 5 minutes. The single-side, single-roller design allows dynamic tension measurement simply by threading the wire around it. The product range covers multiple specifications from 0-5N to 0-50N, with a standard output of 1.5~2.0mV/V. Optional built-in amplified signals of 0-5V, 0-10V, or 4-20mA are available as needed, and it supports a standard DC 5~12V power supply.

The sensor features an aluminum alloy housing with an IP65 protection rating, capable of stable operation in industrial environments from -20°C to 80°C. It is widely used for tension monitoring of ultra-fine metal wires, optical fibers, yarns, sutures, and other products, and is suitable for applications in electronics processing, fiber optic communications, textiles, medical devices, and scientific research, providing reliable support for precise tension control.
