ESMTS550A 50kg Sheet Steel Micro Load Cell Sensor for Hook Scales and Luggage Scales
Working Principle
When an object is placed on a sensor, gravity causes the elastomer of the sensor to undergo slight elastic deformation. The strain gauges attached to the elastomer also deform accordingly, resulting in a change in their resistance. The strain gauges are usually connected in a Wheatstone bridge circuit, and the change in resistance causes the bridge to become unbalanced, thereby outputting a faint voltage signal proportional to the gravity applied. This signal is then processed through amplification, filtering, and A/D conversion, ultimately converting it into a display of the object's weight.
Product Features
1. High precision and high sensitivity: Capable of detecting minute weight changes, with an accuracy of one ten-thousandth or even higher, and the output signal has a highly linear relationship with the applied load, ensuring measurement accuracy.
2. Good stability: Exhibits minimal drift over long-term use, good repeatability, and can maintain stable performance under different environmental conditions.
3. Fast response speed: Excellent dynamic response performance, suitable for dynamic weighing (such as belt scales and checkweighers) and rapid weighing scenarios.
4. Robust structure and strong durability: Typically made of stainless steel or alloy steel, with good overload, impact, and fatigue resistance, suitable for harsh industrial environments.
5. Standardized output signal: Common output is in millivolts (mV), making it easy to integrate with displays and data acquisition systems.
APPLICATION SCENARIOS
1. Industrial Production and Manufacturing: Used for material measurement and batching, lifting and hoisting safety, production line inspection, material testing equipment, etc.
2. Commercial Trade and Logistics: Used for electronic scales and platform scales, logistics package weighing, supermarket checkout scales, etc.
3. Medical and Healthcare Field: Used for body scales, pet scales, weight monitoring in medical equipment, etc.
4. Scientific Research and Experiments: Used for precision weighing in laboratories, material mechanical property testing, etc.
