型号描述

符合卫生要求的电导率传感器 8221 适合测量溶液中的电导率。由于采用卫生设计和坚固结构，这种电导率传感器适合食品和制药工业，以及生物技术和化学工业。传感器根据四极原理设计而成，能够避免类似于二极单元中所出现的极化效应。在此，需要在整个测量范围确保一个优质的线性化特征。在所有版本中，都会集成安装一个温度探测器 (Pt1000)。

1）4 极技术，适合较宽的测量范围 0.1 S...500 mS/cm
2）适合卫生应用领域的过程接口、材料和表面质量
3）可配合蒸汽消毒和 CIP 清洁用的型号 8221，所有与介质相接触的部件均具 FDA 许可

Type Description

The 8221 Hygienic conductivity sensors areused to determine electrical conductivity insolutions. Due to their hygienic design and the robust layout, these conductivity sensors are suitable for use under demanding conditions in food & beverage, pharmaceutical, biotechnology and the general chemical industry. The sensors are based on the 4-electrode principle which excludes polarization phenomena normally observed with 2-electrode sensors. The engineered design guarantees an excellentlinearity over a wide conductivity range ofmore than 6 decades. An integrated temperature sensor (Pt1000) is astandard feature of all versions.

1）4-electrode technology for extended measuring range 0.1 S...500 mS/cm
2）Process connections, materials, surface finish designed for use in hygienic applications
3）Suitable for steam sterilization, CIP (Clean in place)
