ESMLS09A2 10kg 20kg 50kg 100kg 200kg 500kg Micro load cell sensor for electronic balances

The ESMLS09A2 miniature membrane box-type weighing sensor is a precision force measurement instrument based on the strain principle. It is widely used in key testers, press machine pressure detection, robotic gripper force detection, industrial automation measurement and control, and can also be used for precise weighing in platform scales, electronic balances, packaging scales, and other equipment.

Application Scenarios:
1. Industrial Weighing and Automation
Static weighing equipment such as platform scales, truck scales, and rail scales.
Dynamic force measurement systems such as belt scales and electromechanical scales for real-time material flow monitoring.
2. Extreme Environment Monitoring
Aerospace: Monitoring during liquid oxygen fuel filling processes.
Semiconductor manufacturing: Microforce measurement under cleanliness requirements.
Food and pharmaceutical: Direct contact with media in sterile filling equipment, resistant to high-temperature CIP/SIP cleaning.
3. Special Industry Requirements
Biopharmaceutical: Pressure control in bioreactors.
Energy: Monitoring of pressure vessels in nuclear power plants, radiation-resistant design.

Working Principle

ESMLS09A2 Membrane Box Weighing Sensor elastomer (diaphragm) undergoes elastic deformation under an external force, causing the resistance of the strain gauges pasted on its surface to change accordingly. The measuring circuit converts the resistance change into an electrical signal, which, after amplification, outputs a voltage or current signal proportional to the external force, thereby achieving the conversion from weight to electrical signal.

Product Features

Compact and durable, suitable for harsh environments
1. Fully sealed welded structure
Uses an integrated design of stainless steel diaphragm and housing, with no moving parts, extremely low leakage rate, high protection level, resistant to high-pressure steam cleaning, suitable for food, pharmaceutical, chemical, and other scenarios requiring strict cleanliness.
2. Off-center load resistance and corrosion-resistant design
The off-center load resistance is 10 times higher than that of traditional S-type sensors, reducing the impact of installation errors.
Alloy steel or stainless steel design
3. Miniaturization and integration
Low height, small volume, supports flange installation, suitable for space-constrained integrated scenarios (such as fully electric injection molding machines, belt scales).
Provides standard signal output, facilitating connection with automation systems.
