What are Load cells?
A load cell is a force measurement sensor that transforms mechanical energy into electrical energy. Commercial and industrial systems use them for accurate weight management and force calculation. They are essential as they ensure accuracy, efficiency, and safety in the business processing automation and weighing systems. You can find various types of load cells and uses below.
How Does It Work?
Different types of load cell sensors have different working principles and processes. They commonly convert force into an electrical signal. This mechanism varies significantly between hydraulic, pneumatic, and strain gauge load cell types. Generally, a load sensor mechanism used in strain gauge load cell sensors has the following workflow:
- Force Application (Physical force (Pressure, Compression, or Tension) applied to the Load Cell.)
- Strain Gauges Reaction (Load cell material minute deformation, strain gauges are bonded.)
- Electrical Signal Generation (Deformation changes the electrical resistance in the strain gauges.)
- Signal Amplification (Small voltage change transformed to measurable electrical signals.)
- Data Interpretation (Signal calibrated and converted as a weight or force value.)
Types of Load Cells and Uses
From industrial weighing to framework testing, all types of load cells are optimized based on the force direction, precision levels, and environmental conditions. Thus, different load cells cater to different applications. Due to this, it becomes necessary to understand all load cell types.
What are the Types of Load Cells?
The load cells are chiefly divided into 5 types. All types of load cells and uses are specified below. Each of them carries unique features and is used for specific applications.
1. Strain Gauge Load Cell
A strain gauge load cell is a transducer that measures force and transforms it into an electrical signal. This type of load cell is popularly used in modern applications, thanks to its high reliability and accuracy.
It utilizes strain gauges (sensitive to deformation) to detect changes in resistance whenever an external force is applied. These changes are transformed into computable electrical output. This indicates the force magnitude.
Strain Gauge Load Cell USPs:
- Material Deformation Based
- High Accuracy Under Varying Loads
- Popularly used in Weighbridges and Tanks
- Suitable for Static and Dynamic Loads
- Cost-effective and Compact
2. Hydraulic Load Cell
Our load cell types list includes a hydraulic load cell, which is a weight or force sensor. This uses hydraulic pressure to calculate applied loads. It transforms force into pressure change within a limited fluid. This change is measured to discover the applied weight or force.
They are popular for durability, precision, and reliability. This type of load cell is ideal for harsh environments where no electricity is required. It utilizes fluid pressure changes to calculate force.
Hydraulic Load Cell USPs:
- Works without Electricity
- Suitable for Outdoor Areas
- Durable and Resilient
- Less Sensitive than Others
- Non-linear Output (Compared to digital sensors)
3. Pneumatic Load Cell
Our load cell types list includes a pneumatic load cell, a force transducer that utilizes air pressure to measure force or weight. People popularize them for their temperature insensitivity, making them highly suitable for use in clean and secure work surroundings. They measure small weights.
It offers clear, explosion-proof operations appropriate for sensitive environments. It balances an applied force with accurately regulated air pressure, with the final pressure being proportional to the applied force.
Pneumatic Load Cell USPs:
- Highly Secure in Explosive Surroundings
- No Sparking Risk
- Suitable for Food & Pharma Sectors
- Less Accurate than a Strain Gauge
- Requires a Consistent Air Supply
4. Compression Load Cell
Our load cell types list includes compression load cells, transducers that convert weight or force into an electrical signal. They are designed to measure force under compression, common in platform scales and silos. The strain gauges are attached to the body of the load cell.
Under compressive load, the body of these load cells deforms slightly. They measure compressive forces, which are the squash force, applied along a single axis. Most commonly used for measurement & weighing in high-capacity static weight.
Compression Load Cell USPs:
- Downward Force Measured
- Strong Construction
- Ideal for Weighbridges and Tanks
- Handles High Capacity
- Requires Mounting Precision
5. Tension Load Cell
Our load cell types list includes a tension load cell. It is a force sensor developed for measuring tensile forces. These are stretching or pulling forces. These cells are used to measure pulling tension or force in cables, cranes, and hoists.
It transforms the applied tension into an electrical signal. This makes it useful for numerous applications (Industrial Processes, Material Testing, and Structural Monitoring) where the tension measurement is essential.
Tension Load Cell USPs:
- Measures Upward, Pulling Forces
- Suitable for Suspended Weighing
- Used for Material Handling
- Compact with Eye-bolt Ends
- Needs Secure Attachment Points
These are all types of load cells and uses. You can understand and utilize this information while searching for a suitable load cell sensor for your business.
