型號描述
符合衛(wèi)生要求的電導(dǎo)率傳感器 8221 適合測量溶液中的電導(dǎo)率。由于采用衛(wèi)生設(shè)計(jì)和堅(jiān)固結(jié)構(gòu)，這種電導(dǎo)率傳感器適合食品和制藥工業(yè)，以及生物技術(shù)和化學(xué)工業(yè)。傳感器根據(jù)四極原理設(shè)計(jì)而成，能夠避免類似于二極單元中所出現(xiàn)的極化效應(yīng)。在此，需要在整個測量范圍確保一個優(yōu)質(zhì)的線性化特征。在所有版本中，都會集成安裝一個溫度探測器 (Pt1000)。
1）4 極技術(shù)，適合較寬的測量范圍 0.1 ?S...500 mS/cm
2）適合衛(wèi)生應(yīng)用領(lǐng)域的過程接口、材料和表面質(zhì)量
3）可配合蒸汽消毒和 CIP 清潔用的型號 8221，所有與介質(zhì)相接觸的部件均具 FDA 許可
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)
