A weighing pan is the platform component of a precision balance where samples are placed for mass measurement in laboratory and industrial applications.

技术定义与适配语境
典型 称量盘 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

The weighing pan is a critical component of precision balances and analytical balances, serving as the sample placement surface for mass determination. It is designed to provide stable, vibration-damped support for materials while maintaining minimal interference with measurement accuracy. Typically constructed from corrosion-resistant materials, it interfaces directly with the balance's load cell or electromagnetic force restoration mechanism through a suspension system that isolates environmental disturbances.

定义
The weighing pan is a critical component of precision balances and analytical balances, serving as the sample placement surface for mass determination. It is designed to provide stable, vibration-damped support for materials while maintaining minimal interference with measurement accuracy. Typically constructed from corrosion-resistant materials, it interfaces directly with the balance's load cell or electromagnetic force restoration mechanism through a suspension system that isolates environmental disturbances.
工作原理
The weighing pan functions as the primary contact point for samples, transferring gravitational force through a mechanical linkage (often a parallelogram suspension system) to the balance's transducer. This force is converted into an electrical signal proportional to mass. Modern designs incorporate static dissipation, magnetic damping, and temperature compensation to maintain measurement integrity.
材料
Stainless steel (304 or 316 grade)aluminum alloy (anodized)glassor advanced polymers (PTFE-coated). Anti-static coatings and passivated surfaces are common for corrosion resistance and contamination prevention.

常见问题

How often should a weighing pan be calibrated?

Weighing pans themselves don't require calibration, but the complete balance system should be verified daily with certified weights and undergo formal calibration annually per ISO/IEC 17025 requirements.

Can different material weighing pans affect measurement accuracy?

Yes, material choice impacts thermal conductivity, magnetic properties, and electrostatic characteristics. Stainless steel provides optimal stability for most applications, while specialized materials address specific needs like chemical resistance or reduced magnetism.
