電導(dǎo)率是一個(gè)重要的材料屬性,不僅對(duì)金屬傳導(dǎo)電流的能力,也對(duì)其成分、微觀結(jié)構(gòu)和機(jī)械性能提供信息。使SIGMASCOPE® SMP350可以簡(jiǎn)單快速并精確地測(cè)定電導(dǎo)率。SIGMASCOPE® SMP350 根據(jù)渦流相位法DIN EN 2004-1 和 ASTM E 1004 測(cè)量電導(dǎo)率。 這種方法允許無(wú)接觸測(cè)量,即使隔著油漆或者厚達(dá)500μm的塑料涂層,這種方法也幾乎不受表面粗糙度的影響。
Probe FS40HF探頭:
Probe FS40HF探頭根據(jù)DIN EN 2004-1和ASTM E 1004來(lái)測(cè)量非磁性金屬的電導(dǎo)率。由于集成了溫度傳感器,所有探頭都適合進(jìn)行溫度校正的測(cè)量,并自動(dòng)顯示標(biāo)準(zhǔn)化為20°的電導(dǎo)率值 C(68°F)。 所有探頭均在高頻下工作,因此只能在低材料深度下進(jìn)行測(cè)量。 使用的測(cè)量方法可以進(jìn)行無(wú)接觸測(cè)量,也可以在非導(dǎo)電面漆(如漆面或塑料蓋)下進(jìn)行測(cè)量。
