Load Cell vs Force Sensor: Definitions

What is a Load Cell?
A load cell helps you find out weight or force. You use it when you want to know how heavy something is. It also tells you how much force is on an object. Many devices need load cells for correct weight readings.
Principle of Operation
A load cell gets voltage from a power source. When you put force on it, it sends a small signal back. This signal shows the weight or force amount. Most load cells have strain gauges inside. The strain gauge changes resistance when you push on it. This gives you a clear and steady reading.
- A load cell checks weight or force on objects.
- You find load cells in electronic scales.
- You use load cells to set up testing machines.
Typical Applications
You see load cells in many places. They are in big weighing systems at factories. You find them in lab testing machines. Truck scales and packaging lines use them too. These tools need exact weight numbers.
What is a Force Sensor?
A force sensor checks force when you press or squeeze something. You use force sensors in robots, machines, and other areas. They help you notice changes in pressure or touch.
FSR Technology Overview
Force Sensing Resistors, or FSRs, are a kind of force sensor. SOUSHINE’s FSRs have a bendy base, a spacer, and a layer that carries electricity. When you press down, the resistance goes down. This change helps you measure force. FSRs give you force readings all the time. You use them to check moving or touch force.
SOUSHINE FSR Features
SOUSHINE’s FSRs come in many shapes and sizes. You can use them in lots of designs. They last long and do not use much power. They work well in hard places. SOUSHINE gives help and can make special ones for you.

|---|---|---|
| Measurement Type | Measures tensile and compressive forces | Used for weighing applications |
| Calibration Units | Calibrated in newtons | Weighs in kilograms |
| Application | Common in robotics and automation | Used in weighing systems |
| Sensing Technology | Uses various technologies | Uses strain gauges |
You can see that load cells and force sensors are for different jobs. You pick load cells for weight. You pick force sensors for touch or moving force.
Key Differences: Load Cell vs Force Sensor
Measurement Type
You should know what you want to measure first. Load cells measure weight or force and make an electrical signal. You use load cells for things that do not move, like weighing items. Force sensors, like SOUSHINE’s FSRs, measure force in different ways. You use force sensors for things that change quickly, like touch or fast pressure.
Here is a table that shows how each device works in different jobs:
| Device Type | Measurement Type | Application Context |
|---|---|---|
| Load Cell | Converts force/weight to electrical signal | Used for weighing in factories, or research needing exact numbers |
| Force Sensor | Measures force/load using various technologies | Used for quick changes or touch in machines |
Load cells are used when you need exact weight. Force sensors are used when you need to sense fast changes or touch. Each one is good for a different job. Knowing these differences helps you choose the right tool.
Accuracy and Precision
Getting correct results is important. Load cells give very accurate and repeatable results. You use them when you need the exact weight or force every time. Force sensors, like SOUSHINE’s FSRs, also give good results, but you must read them carefully. The precision of force sensors can change, so you should check them often.
Here is a table that compares how accurate and precise both devices are:
| Feature | Load Cells | Force Sensing Resistors (FSRs) |
|---|---|---|
| Accuracy | Very accurate and reliable | Needs careful reading of results |
| Precision | Very precise, same result each time | Less precise, results can change |
You use load cells when you want the same answer every time. You use force sensors when you want to sense changes or touch, even if the answer is not always the same. Accuracy is important when picking between load cells and force sensors.
Durability and Environment
Think about where you will use your sensor. Both load cells and force sensors can have problems in tough places. Things like water, chemicals, dust, heat, electromagnetic interference, and shaking can hurt your sensor.
- Water can cause rust or short circuits.
- Chemicals can damage the sensor.
- Dust can block parts and make readings wrong.
