HAPL-CAL Calibration-Grade Load Cells (Imperial)

The HAPL-CAL Calibration-Grade Load Cells represent one of the highest-performing force measurement solutions available for laboratories and metrology professionals who demand uncompromising accuracy. Engineered for precision verification and traceable force measurement, this sensor is ideally suited for calibration environments where repeatability and confidence in data are essential.

Designed to function as a reference load cell for ASTM E4 calibrations, the HAPL-CAL provides the measurement stability required to validate the performance of universal testing machines and other force-generating systems. Its advanced strain gauge architecture delivers exceptional linearity, minimal hysteresis, and outstanding long-term reliability — critical characteristics when establishing or maintaining calibration compliance.

A defining feature of the HAPL-CAL is its integrated calibration adapter, which enhances both versatility and ease of use. The adapter includes precision-machined imperial threads for tensile calibration, allowing seamless attachment to calibration frames and force verification systems. For compression applications, the built-in radius dome promotes uniform load distribution across the sensor, helping reduce off-axis loading effects that could otherwise influence measurement accuracy.

Constructed from high-strength materials and manufactured to tight tolerances, the HAPL-CAL is capable of maintaining performance under demanding calibration cycles while preserving measurement integrity. Whether utilized in accredited calibration labs, aerospace testing facilities, advanced manufacturing environments, or research institutions, this load cell supports rigorous quality programs and helps ensure testing equipment performs exactly as intended.
