ATO 2000kg Low Profile Pancake Load Cell
Capacity is 2000 kg with a sensitivity of 2.0±0.1 mV/V and an accuracy of 0.05% F.S. The low-profile, flat design delivers high strength and symmetry, making it ideal for platform scales, truck scales, or rail weighbridges where space is at a premium. The IP67 protection plus an all-sealed structure supports harsh environments. Best for: heavy-duty applications with little clearance. Caution: ensure mounting surfaces are precisely aligned to maintain low eccentric loading.
Mini Load Cell Bellows Type 2000 kg
This bellows-style load cell covers a broad range up to 2000 kg with high precision. It offers accuracy of 0.2% of full scale, suitable for weighing and force measurements requiring tight tolerances. The sensor is built from stainless steel and performs reliably from -20°C to 80°C, which supports challenging environments. Best for: high-accuracy tasks in compact spaces. Caution: selection should consider long-term stability under temperature fluctuation.
ATO 1000 kg Pancake Tension/Compression
Capacity options range from 500 kg to 10 ton, with a pancake, low-profile design and strong anti-eccentric performance. This sensor features 0.05% F.S accuracy, sensitivity of 2.0±0.1 mV/V, and a DC bridge voltage of 5–10V. Best for: scalable industrial weighing where higher loads are needed without height increase. Limitation: higher-capacity units may require more stringent mounting to preserve linearity.
ATO 300 kg Spoke Pancake Load Cell
The 300 kg spoke-type load cell, also known as a pancake load cell, emphasizes anti-eccentric load performance and a low profile. With 0.03% F.S accuracy and 2.0±0.1 mV/V sensitivity, it suits precise tension and compression measurements. Best for: tight-space projects needing precise, compact sensors. Caution: ensure mounting hardware matches the spoke design to avoid misalignment.
ATO 1000 kg Pancake Load Cell, Dual-use
Offers high capacity and precision with 0.05% F.S and sensitivity of 2.0±0.1 mV/V. Known as a pancake load cell, the flat design ensures good symmetry and durability, suitable for platform scales, truck scales, rail weighbridges, and warehouse material level control. Best for: versatile industrial weighing requiring reliability across multiple applications. Caution: verify voltage compatibility (DC 5–10V) for your system.
Buying Guide
What capacity do you really need?
- For platform and truck scales, higher capacities like 1000–2000 kg provide flexibility for mixed payloads.
- For small-space projects, 300–1000 kg options can minimize installation height while preserving accuracy.
Why choose a pancake vs. bellows vs. spoke type?
- Pancake (low-profile) sensors are ideal when vertical clearance is limited and symmetry matters for even loading.
- Bellows sensors accommodate broader ranges and can be robust in environmental extremes.
- Spoke-type pancake sensors offer good anti-eccentric performance in compact designs.
How important is accuracy and temperature range?
- Look for classifications like 0.03%–0.05% F.S for tight precision in industrial scales.
- Temperature ranges such as -20°C to 80°C indicate suitability for varied environments.
Electrical and mounting considerations
- Ensure bridge voltage (DC) compatibility and proper excitation (5–10V or 10V) for the unit you select.
- Verify mounting hole patterns and height to prevent eccentric loading and ensure consistent performance.
FAQ
- What is a low-profile load cell? It is a rugged sensor with a flat, compact design that minimizes height while maintaining accuracy for weighing systems.
- Which load cell is best for a platform scale? A pancake-style low-profile load cell with high sensitivity and 0.05% F.S accuracy is typically best for platform scales.
- Can these sensors operate in cold or hot environments? Some models specify broad temperature ranges (for example -20°C to 80°C), but always match the sensor to your environment.
- Do all low-profile load cells require the same excitation voltage? No. Some models use 5–10V DC, others up to 10V; check the exact specification for your chosen unit.
- What about anti-eccentric performance? Spoke and pancake designs usually emphasize good anti-eccentric load performance, which improves precision under uneven loading.
- How do I choose between 1000 kg and 2000 kg options? Consider the maximum possible load, potential future payloads, and the available installation space to avoid overbuilding or undersizing the sensor.
