ESMLS08A steel wire ropes side-pressure type tension sensor for 1~20t
Working Principle
The ESMLS08A tension sensor is based on the principle of gravitational equivalence and the resistive strain effect. By applying a small force in the direction of the measured tension, called lateral pressure, perpendicular to the tension direction to form a planar angle, the principle of gravitational equivalence is used to equate the two into directly measurable tension. The lateral pressure causes the strain gauge in the sensor to undergo strain deformation, and the change in the strain gauge's resistance is measured through a bridge circuit to obtain the tension data.
Product Features
1. Clamp-style installation, no need to cut the wire rope
Directly clamped onto the outside of the wire rope, without damaging the original structure; easy to install, remove, and maintain.
2. Wide applicability, compatible with various rope diameters
Can fit commonly used wire ropes with diameters of Φ6–Φ36mm, with a capacity range of 0.5t–20t, suitable for cranes, winches, cableways, and other scenarios.
3. Double-hole shear beam design, high precision and excellent stability
Strong resistance to eccentric loads and lateral forces, with superior nonlinearity, hysteresis, and repeatability; minimal long-term drift.
4. Accurate measurement in static or slow-moving states
Designed specifically for static and low-speed tension monitoring of wire ropes, providing stable force measurements and reliable data.
5. Fully sealed structure, high protection level
Fully sealed and epoxy-filled, corrosion-proof, waterproof, dust-proof; rated IP65 and above, suitable for harsh industrial environments.
6. Standard signal output, easy integration with control systems
Equipped with standard mV/V signal; can be paired with amplifiers to output 4–20mA / 0–10V / RS485, facilitating connection to PLCs, displays, and alarm systems.
7. Robust structure, strong overload capacity
Constructed from alloy steel or stainless steel; safe overload capacity up to 150% FS, impact-resistant, and highly durable.
8. Specialized application, top choice for safety protection
Mainly used for cranes, tower cranes, winches, hoists, wire rope tension monitoring, and overload protection, ensuring safe equipment operation.
