Key specifications include 2000 kg capacity, 0.05% full-scale accuracy (covering linearity, hysteresis, and repeatability), and a compact footprint that facilitates installation in confined spaces. The combination of a low height and complete sealing ensures stable performance under challenging industrial environments. Users should pair it with a suitable DC excitation supply and a compatible signal conditioner to capture accurate weight data.
ATO Tension And Compression Pancake Load Cell 1000kg/5ton/10ton
This family of pancake, spoke-type load cells covers capacities from 500 kg up to 10 tons, offering strong anti-eccentric performance and a compact, low-profile design. With a sensitivity of 2.0 ± 0.1 mV/V and an accuracy rating of 0.05% F.S. (encompassing linearity, hysteresis, and repeatability), these sensors are well-suited for scales and testing rigs that demand dependable, repeatable readings under tension and compression. DC excitation in the 5–10 V range is typical for operation, and the versatile capacity range makes them adaptable to evolving measurement needs.
Engineering teams should consider load cell mounting geometry, wiring configuration, and connector compatibility when integrating this sensor into existing instrumentation. The spoke-type geometry helps distribute load evenly, reducing the impact of misalignment on measurement quality. For best results, ensure a rigid mounting surface and apply proper calibration procedures to maintain accuracy across temperature fluctuations and repeated use.
ATO 300 kg Tension And Compression Load Cell
The 300 kg ATO spoke-type load cell is a compact pancake-style sensor designed for precise force measurement in tight spaces. Its low-profile form factor, combined with excellent anti-eccentric load performance, makes it suitable for scale platforms and testing rigs where space constraints exist. The sensor offers 0.03% F.S. accuracy (linear, hysteresis, and repeatability) with a sensitivity of 2.0 ± 0.1 mV/V, typically featuring a DC excitation around 10 V. This combination yields reliable, repeatable outputs across a broad operating range, ideal for laboratory and industrial weighing tasks.
Practical considerations include ensuring clean signal connections and selecting a compatible signal conditioner. The pancake design distributes loads efficiently, but correct mounting and alignment are essential to minimize measurement bias. Consider environmental protections if the device will operate in dusty or humid environments, and plan calibration intervals to maintain peak performance.
QILICHUANGAN Mini Bellows Load Cell 0–50 kg
This bellows-type miniature load cell spans 0–50 kg to accommodate precise force measurements in tight spaces. It emphasizes high-precision weighing with an accuracy around 0.2% of full scale, along with strong anti-interference characteristics. Constructed from stainless steel, the device maintains stability across a wide temperature range and challenging environmental conditions. Its compact diameter and flexible mounting options enable use in small-scale weighing setups, force testing rigs, and research prototypes where space is at a premium.
The sensor’s bellows design reduces dead space and improves sealing integrity, which is beneficial in environments with dust or moisture. Calibration should account for sensor temperature sensitivity and any nonlinearity at the lower end of the range. Pairing with a robust signal conditioner ensures signal integrity and accurate digital readouts.
QILICHUANGAN S-Type Load Cell 0–500 KG
The S-type load cell from QILICHUANGAN provides a versatile option for both tension and compression measurements within a 0–500 kg range. It offers high-precision measurement with about 0.2% accuracy, making it suitable for static weighing and dynamic testing scenarios. Dual relay outputs allow automatic switching based on preset thresholds, which can support automation, alarms, or data logging in control systems. The design emphasizes reliable performance with stable readings across a range of operating conditions.
In deployment, ensure proper cabling, appropriate relay configuration, and adequate protection from electromagnetic interference. Temperature fluctuations can influence readings, so consider temperature compensation or enclosure where needed. This sensor is well-suited for scale testing, lab experiments, and process monitoring where compact form and reliable performance matter.
QILICHUANGAN Mini Bellows 0–20 kg
This mini bellows load cell covers 0–20 kg, with a high-precision rating of about 0.2% accuracy. Its stainless steel construction and wide operating temperature range (-20°C to 80°C) support long-term stability in varied environments.

As with other bellows sensors, ensure proper mounting, consider protection from dust and moisture, and select compatible electronics to interpret the output accurately. Periodic calibration is recommended to preserve measurement fidelity across usage cycles and environmental changes.
CALT DYLY-103 Tension And Compression Sensor S Beam
The CALT DYLY-103 is a tension and compression sensor built as an S-beam load cell, offering a 100 kg rating with hermetic sealing. It emphasizes high accuracy and stable performance through sealed construction, making it suitable for applications where fluids or contaminants could affect measurement integrity. This type of load cell is commonly chosen for force testing rigs, small-scale platform scales, and laboratory experiments where a compact, reliable sensor is required.
Design considerations include ensuring secure attachment to load points and selecting a compatible signal conditioner. The hermetically sealed design provides added protection in humid or dusty environments, but it is important to account for calibration drift due to temperature changes. The S-beam geometry supports versatile mounting patterns for various test configurations.
Buying Guide: Key Purchase Considerations And Comparisons
- Capacity vs. application: Choose a sensor whose rated capacity matches your load profile, with a safety margin for peak loads. Pancake (spoke) styles excel on compact platforms; bellows types handle dynamic environments with higher protection needs.
- Accuracy and repeatability: Look for specified full-scale accuracy (e.g., 0.03%–0.05% F.S.) and stable repeatability to minimize calibration drift and measurement bias over time.
- Sensitivity and excitation: Ensure compatible sensitivity (e.g., 2.0 ± 0.1 mV/V) and a suitable excitation voltage (DC 5–10 V or similar) that your instrumentation can supply.
- Environmental protection: IP ratings and stainless-steel construction are critical for dust, moisture, and temperature resilience. Consider hermetic sealing for harsh environments.
- Mounting geometry: Pancake and S-beam designs require proper mounting surfaces and alignment to reduce eccentric loading. Verify thread sizes and mounting hole configurations.
- Signal conditioning: A stable bridge signal requires an appropriate instrumentation amplifier or data acquisition module. Plan for cable length, EMI shielding, and shielding grounds.
- Calibration and drift: Regular calibration checks help maintain accuracy. Evaluate how temperature, humidity, and vibration may affect readings and plan compensation accordingly.
- Maintenance and longevity: Stainless steel, sealed enclosures, and robust wiring reduce maintenance frequency. Consider ease of installation and replacement if needed.
- Cost vs. performance: Balance initial cost with accuracy, capacity, protection features, and expected lifecycle to determine total value over the sensor’s use case.
