随着科技进步的发展,称重设备越来越趋向自动化技术和智能化。因为很多客户没有适当选择和使用电子天平,促使电子天平与具体规定不符,影响正常检验工作中,并导致浪费。本文融合电子天平的技术特性,对电子天平的选择及使用规定做简单介绍。

FA系列电子天平

准确度规定

选择电子天平,首先需从相对天平的分度值是不是合乎称重的准确度规定考虑。

在选择电子天平的分度值时,应参照生产厂家得出的检定分度值e,而不是具体分度值d。

现阶段国家计量检定技术规范要求,分辨天平是不是达标,是以检定分度值来衡量,容许偏差范围是(0.5~1.5)e。有刻度、有辅助设备的天平(如电子天平),检定分度值由生产厂家依据准确度级别表和下列标准选定:d < e ≤ 10d

尤其留意的是,现阶段销售市场上很多电子秤根据电子天平规范开展生产e=2d或e=5d甚至e=10d,并不符合我国计量检定技术规范电子秤e=d的规定,选购时更应了解清晰。

秤量规定

选择电子天平也要看天平的量程是不是考虑秤量规定,一般取常见大荷载再加20%上下保险指数即可。量程并并不是越大越好,由于同样精度的天平,量程越大,对天平传感器和辅助机器设备的规定越高,且价格也越贵。
