Mini Load Cell Bellows Sensor 0-200kg
The Mini Load Cell Force Weight Sensor uses a bellows design and stainless steel housing, offering a wide range of capacities from 20 kg to 2000 kg. With an accuracy specification around 0.3% at its maximum range and an operating temperature span of -20℃ to 80℃, it suits laboratory and industrial setups requiring stable readings across environmental changes. This option is best for compact testing rigs where space is limited but precision remains critical. Consider potential sensitivity to mechanical misalignment, which can affect readings in dynamic setups.
Load Cell Force Sensor 0-100 kg
This 0-100 kg load cell offers 0.1% precision across a broad capacity range, making it versatile for both light-duty tasks and heavier industrial reads. Its rod-type design supports tension and compression, simplifying integration into test benches, machinery monitoring, and custom fixtures. Constructed in stainless steel, it resists corrosion and environmental wear. Best for engineers needing repeatable readings in semi-industrial environments; avoid if you require ultra-lightweight or ultra-miniature sensors.
Load Cell Force Sensor 0-20 kg
This 0-20 kg sensor provides 0.1% precision and a robust rod-type design for both tension and compression. Stainless steel construction ensures corrosion resistance and durability in workshops or outdoor sites. It’s ideal for precise force measurement on small benches or testing rigs that require reliable measurements in a compact form. A limitation is that capacity caps at 20 kg, making it unsuitable for higher-load applications.
Micro Load Cell Bellows Sensor 0-5 kg
The Micro Load Cell uses a bellows-type compression design with 0.02% FS accuracy and a compact footprint. This makes it suitable for space-constrained weighing tasks and precision measurement in limited-space equipment. It offers robust resistance to eccentric loads, which helps maintain accuracy. Best for tight installations; consider its smaller maximum capacity if larger forces may be encountered.
Rice Lake 1000 lb Load Cell
This 1000 lb capacity load cell from Rice Lake is designed for industrial weighing that requires rugged sealing and IP68-rated protection. Its environmentally sealed design supports dirt, dust, and moisture exposure in challenging settings. Best for scale systems, batch weighing, and materials handling. A limitation is its higher capacity and larger size, which may require more substantial mounting provisions and space.
Buying Guide
What to consider when choosing load cell cables and sensors:
- Capacity and range: Match the maximum expected load to prevent overloading and ensure accurate readings.
- Accuracy and tolerance: Look for specified percent accuracy (e.g., 0.1%, 0.2%) relevant to your application’s precision needs.
- Construction: Stainless steel and proper sealing (IP ratings) improve durability in harsh environments.
- Design type: Rod-type (tie-rod) is common for tension and compression; bellows designs offer robustness for certain dynamic loads.
- Cable length and installation: Ensure cables are long enough for your setup and include mounting holes or fixtures as needed.
- Environment: Temperature range and exposure to moisture, dust, or corrosive elements should guide material choice.
How to compare options
- Best for space-constrained benches: Micro and 0-5 kg bellows sensors.
- Best for mid-range tasks: 0-100 kg with rod-type design.
- Best for industrial use: High-capacity units like 1000 lb load cells with IP ratings.
- Best for general lab and test rigs: 0-20 kg and 0-100 kg options with stainless steel construction.
FAQ
- Q: Do these sensors measure both tension and compression? A: Yes, several models feature rod-type designs suitable for both tension and compression.
- Q: What does 0.1% accuracy mean? A: It indicates a very small deviation from true force, improving repeatability in measurements.
- Q: Are these sensors compatible with standard signal interfaces? A: Most feature standard wiring and mounting options; verify your data acquisition system’s input requirements.
- Q: Can I use any load cell outdoors? A: Choose models with stainless steel construction and appropriate IP ratings for environmental exposure.
- Q: How do I choose the right capacity? A: Base the choice on the maximum force you expect to measure plus a safety margin to avoid saturation.
- Q: Do these cables affect accuracy? A: Cable length and shielding can influence readings; use recommended cable lengths and secure connections to minimize noise.
