Rosemount罗斯蒙特3051TG3A2B21AB4M5K5TK电导率与电阻率互为倒数关系。即导电率＝1/电阻率电阻率：是用来表示各种物质电阻特性的物理量。某种材料制成的长1米、横截面积是1平方毫米的导线的电阻，叫做这种材料的电阻率。国际单位制中，电阻率的单位是欧姆·米，常用单位是欧姆·平方毫米/米。电阻率的计算公式为：ρ=RS/Lρ为电阻率——单位Ω·mS为横截面积——单位㎡R为电阻值——单位ΩL为导线的长度——单位m电导率是物体传导电流的能力。电导率测量仪的测量原理是将两块平行的极板，放到被测溶液中，在极板的两端加上一定的电势（通常为正弦波电压），然后测量极板间流过的电流。根据欧姆定律，电导率(G)--电阻(R)的倒数，是由电压和电流决定的。电导率的基本单位是西门子（S），原来被称为姆欧，取电阻单位欧姆倒数之意。因为电导池的几何形状影响电导率值，标准的测量中用单位电导率S/cm来表示，以补偿各种电极尺寸造成的差别。单位电导率（C）简单的说是所测电导率（G）与电导池常数(L/A)的乘积.这里的L为两块极板之间的液柱长度，A为极板的面积。=ρl=l/σ(1)定义或解释电阻率的倒数为电导率。σ=1/ρ(2)单位:在国际单位制中,电导率的单位是西门子/米。(3)说明电导率的物理意义是表示物质导电的性能。电导率越大则导电性能越强,反之越小。1756-M241756-L55M121756-L55M131756-L55M141756-L55M161756-L55M221756-L55M231756-L55M241785-L11B1785-L20B1785-L20C151785-L20E1785-L26B1785-L30B1785-L40B1785-L40C1785-L40C151785-L40E1785-L40L1785-L46B1785-L46C151785-L60B1785-L60L1785-L80B1785-L80C1785-L80C151785-L80E1785-L86B1747-L5141747-L5331747-L5421747-L5431747-L5511747-L5521747-L5531747-L553P1756-L11756-L1M11756-L1M21756-L1M31756-L551756-DNB1756-IB161756-IB16D1756-IB16I1756-IB321756-IC161756-IH16I1756-IM16I1756-IN161756-IV161756-OB16D1756-OB16E1756-OB16I1756-OB321756-OB81756-OB8EI1756-OC81756-ON81756-OV16E1756-OW16I1756-OX8I1756-IF161756-IF6I1756-IF81756-IR6I1756-IT6I1756-OF41756-OF6CI1756-OF6VI1756-OF81756-HSC1756-CNB1756-CNBR1756-ENBT1756-DHRIO1756-DNB1756-L611756-L61S1756-L621756-L62S1756-L631756-L63S1756-L63XT1756-L641756-L651756-L731756-L751756-L551756-L551756-L55M121756-L55M131756-L55M141756-L55M161756-L55M221756-L55M231756-L55M241756-L60M03SE1756-L611756-L61S1756-L621756-L62S1756-L631756-L63S1756-L641756-LSP1756-M121756-M131756-M141756-M161756-M221756-M231756-M241756-IF161756-IF4FXOF2F1756-IF6CIS1756-IF6I1756-IR6I1756-IT6I1756-IT6I21756-OF6CI1756-OF6VI1756-OF81756-OF8H1756-CFM1756-HYD021756-PLS1756-M02AE1756-M02AS1756-M08SE1756-M16SE1756-CN21756-CN2R1756-CNBR1756-EN2T1756-ENBT1756-EWEB1756-DHRIO1756-PBR21756-SYNCH1756-STRT41756-PAR21756-EN2TR1756-CN2R1756-CNBR1756-M02AE1756-M02AS1756-M08SE1756-M16SE1756-RM1756sc-CTR81756sc-IF8H1756sc-IF8u1756sc-OF8H1756-L561756-L571756-L581756-L591756-L601756-L611756-L621756-L631756-L641756-L651756-L661756-L62S1756-L631756-L641756-L651756-LSP1785-L60L1785-L40L1785-L80E1785-L86B1785-L80C151785-L80B1785-L60B1785-L46C151785-L40E1785-L46B1785-L40C151785-L40B1785-L30B1785-L26B1785-L20E1785-L20C151785-L20B1785-BCM1785-BEM1785-L11B1785-KA1785-CHBM1785-KE1785-KA31785-ENET1785-KA5P1785-M1001785-ME641785-ME321785-ME161785-TAM1785-TBM1785-TAS1785-TBS1785-TR10B51785-ACC5LA1785-ACC5LB1771-LC3B1771-QDC1771-IFMS1771-L***B1771-DR1771-QI1771-ES1771-QA1771-DE1771-TCMR1771-LC5B1771-NBVC1771-NBV11771-NBTC1771-NBSC1771-NBRC1771-NOV1771-QB1771-NT21771-NOC1771-NIS1771-NR1771-KF1771-KE1771-IXHR1771-NIVR1771-IL1771-NT11771-NIVT1771-TCM1771-IXE1771-NIV1771-NIV11771-CFM1771-SPI1771-VHSC1771-IR1771-DB1771-PT41771-M31771-DA1771-PM)
