DYMH-103 10kg Mini Load Cell
The DYMH-103 10kg Mini Tension and Compression Load Cell from CALT targets compact installations where space is at a premium. It supports a 0-10 kg range with high accuracy and good stability. Its stainless steel construction enhances durability in demanding environments, while a sensitivity specification of 1.0-1.5 mV/V supports precise readings when paired with compatible amplifiers or readouts.
DYMH-103 300kg Mini Load Cell
Designed for space-limited setups yet capable of handling higher loads, this 0-300 kg version from CALT maintains compact form without sacrificing stability or accuracy. With stainless steel construction and a similar 1.0-1.5 mV/V sensitivity, it provides reliable force measurements in test rigs, squeeze tests, or automated inspection lines where footprint constraints exist.
QILICHUANGAN Load Cell With Indicator
This compression load cell with an integrated indicator provides easy-to-read results via a five-digit LED display and a peak-hold feature to capture maximum force values. The bellows-style sensor and precision readouts support stable long-term monitoring in industrial weighing, quality control, and peak-force testing applications where a standalone indicator is preferred.
DEFY 1K S-Type Load Cell
The DEFY 1K S-Type Load Cell from KELI offers a classic S-shaped configuration with 1000 lb (approximately 454 kg) capacity and high sensitivity, suitable for material testing, automation, and general force measurement. Its low-deflection design helps maintain accuracy under repetitive loading, with robust materials intended for industrial environments.
ATO 500kg Pancake Load Cell
ATO’s 500 kg pancake-style load cell is a compact, low-height option with a sealed structure, making it suitable for precision weighing and force measurement in constrained spaces. It delivers an accuracy specification of 0.05% F.S., with a high-precision strain gauge setup designed to minimize error from non-axial loads or minor misalignment, which is important in quality control and automation projects.
Buying Guide
Choosing the right low force load cell involves balancing range, sensitivity, and environmental resilience. Key considerations include:
- Application range: For tiny testing rigs, 0-10 kg to 0-100 kg models minimize size while preserving accuracy. For heavier but still compact applications, 0-300 kg or up to 500 kg options are common.
- Output and compatibility: Sensitivity values like 1.0-1.5 mV/V require appropriate signal conditioning, amplifiers, or data acquisition systems to maximize resolution and calibrate for linearity.
- Material and durability: Stainless steel versions offer corrosion resistance and stability in harsh environments; bellows designs improve anti-bias performance in dynamic scenarios.
- Form factor: Pancake and S-Type designs provide compact profiles and easy mounting; consider height and footprint relative to mounting surfaces.
- Seal and protection: Sealed or IP-rated builds help in damp or dusty environments, reducing long-term drift and maintenance needs.
- Calibration and repeatability: Look for low deflection and rigorous F.S. accuracy specifications to ensure consistent readings across cycles.
In practice, a combination of a small-capacity cell (for primary measurements) paired with a higher-capacity sensor (for overload protection or testing of heavier loads) can offer a versatile, scalable setup. For users prioritizing space, pancake-style or inline compact cells paired with a suitable signal conditioner tend to yield the best balance of form factor and data quality.
