Product Overview

Product Overview

The SLM series ultra-thin tension sensors feature a waterproof, dustproof, and corrosion-resistant design with built-in bearings, allowing for installation with idler or live rollers. The SLM series sensors are compact, making them particularly suitable for space-constrained applications. They can be directly mounted on the equipment's vertical plate or installed on the equipment frame via a shaft mount. Their through-shaft design makes them widely applicable to various winding equipment.

Product Features

Product Features

High output signal response frequency

Good linearity of output signal

Built-in temperature compensation network, minimal temperature drift

It has the same high sensitivity to both high and low tension.

The effective tension detection range is wide, up to 45:1.

Special processes are employed to ensure high bonding strength between the strain gauge and the substrate.

The sensor has a built-in overload protection system with an overload capacity of up to 500%.

Industrialized dustproof and corrosion-resistant process design

Made of special alloys, sturdy and durable

The sensor uses self-aligning ball bearings to eliminate roller deflection and misalignment errors.

Can be installed with idler rollers or live rollers.
