Being an indispensable core component of power equipment, construction machinery, various working machinery, and industrial automation systems, the calibration of the force transducer is crucial. This paper proposes a continuous force standard machine for calibrating force transducers, which combines the advantages of the common force standard machines and the Kibble balance. The goal of the proposed standard machine is to continuously measure the electromagnetic force and trace the force to Planck constant <em>h</em>. In the proposed design, the standard electromagnetic force of kilonewton magnitude is generated by the permanent magnet and coil system, which can be continuously changed by adjusting the magnitude and direction of the coil current. The electromagnetic force, amplified by the unequal arm balance lever, acts on the calibrated transducer. Herein, the concrete components of the new force standard machine are given, and the feasibility is demonstrated.</div></div>","PeriodicalId":34311,"journal":{"name":"Measurement Sensors","volume":"38 ","pages":"Article 101368"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The acceleration measurement by absolute method is the developing direction of sinusoidal force measurement. Besides, the influence of acceleration distribution of mass block should be taken into consideration. The size, density, and Young's modulus of the mass block affect the acceleration distribution. The study demonstrates that the uniform acceleration distribution in materials like steel and cemented carbide leads to more accurate calibration outcomes, the diameter and height of the mass block have a significant influence on the distribution of acceleration. The vibration frequency of sinusoidal force directly affects the dynamic calibration result of the sensitivity of the force sensor, and the natural frequency of standard devices of sinusoidal force calibration is affected by the mass block dramatically. Therefore, it is suggested that an international standard for dynamic calibration of force transducers based on sinusoidal methods should be formulated to resolve the differences between the relevant technical standards and the requirements of calibration items and methods for force transducers among various countries. Therefore, the unified calculation method and quantity values of dynamic calibration of force transducers according to the sinusoidal method can be achieved.</div></div>","PeriodicalId":34311,"journal":{"name":"Measurement Sensors","volume":"38 ","pages":"Article 101373"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144213196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
