Type SM40F Side Pressure Load Cell

The sensor is made of alloy steel or stainless steel and has a unique press-type structure. The working principle is that the wire rope is fixed on the sensor through the U-shaped bolt (or press block + bolt) and the two ends of the groove, when the wire rope is subjected to tension, the force is applied to the sensor through the guide rotation. It is suitable for measuring and controlling the tension of wire rope. It is mainly used in lifting equipment such as electric hoist, material hoist and wire rope hoist.

Dimensions:（In mm. 1mm=0.03937 inches）

Structure and materials
Material: Usually made of alloy steel or stainless steel, it has good corrosion resistance and high strength, and can work stably in harsh environments.
Side pressure design: The sensor adopts a side pressure structure, which enables it to accurately sense the force transmitted by the wire rope without directly bearing the tension.

Working principle
Force transmission: The wire rope is fixed to the sensor by U-bolts or pressure blocks. When the wire rope is subjected to tension, the force is transmitted to the sensor through the guide wheel, activating the internal measuring element (such as strain gauge) to convert the mechanical force into an electrical signal.
Signal output: The generated electrical signal can be output in analog or digital mode, which is convenient for connecting to the control system for real-time monitoring and adjustment.

Main functions
Tension monitoring: Real-time monitoring of the tension of the wire rope to ensure that it is within the safe range and prevent overload.
Data feedback: Provide accurate tension data to help operators make decisions and optimize lifting operations.

Application areas
Electric hoist: Used to monitor the tension of the wire rope during lifting to ensure safety.
Material hoist: Ensure that the appropriate tension is maintained during lifting operations to avoid accidents.
Lifting equipment: widely used in various lifting machinery, such as cranes, lifting platforms, etc.

Advantages and characteristics
High precision: can provide accurate tension measurement and improve operation safety.
Durability: sturdy design, adaptable to a variety of harsh working environments, long service life.
Easy to install and maintain: simple structure, easy to integrate into existing systems, easy to maintain.
