871CR CONTACTING CONDUCTIVITY AND RESISTIVITY SENSORS FOXBORO

The Foxboro® brand 871CR Series contacting conductivity and resistivity sensors are suitable for ionic measurements in most clean water applications found in power, semiconductor, pharmaceutical, and other process industries. Application flexibility is enhanced by the choice of insulator materials and numerous mounting hardware accessories. These sensors conform to all applicable European Union Directives when used with Models 876CR and 870ITCR Intelligent Transmitters, or a Model 875CR Intelligent Analyzer.

INTRODUCTION

The 871CR Series Sensors measure the conductivity or resistivity of a solution. These sensors, together with 876CR or 870ITCR Intelligent Electrochemical Transmitter, or an 875CR Intelligent Electrochemical Analyzer, are used in a broad range of applications including critical ultrapure water resistivity measurements found in the semiconductor industry, and conductivity measurements used in power and pharmaceutical water measurements.

APPLICATION FLEXIBILITY

Two cell factors, 0.1 cm-1 and 10 cm-1, are available for ionic measurements. The cell factor used is dictated by the measurement range desired. The sensors are constructed of different materials, standard and extended insertion lengths, and many mounting options. The sliding bore piece design provides easy installation and reduces replacement costs since normally the mounting hardware is permanently installed in the process system.
