871CR Series Contacting Conductivity and Resistivity Sensors and Accessories
The Schneider Electric® 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.
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.
features
- 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.
- QUALITY AND UNIFORMITY
- 871CR sensors are manufactured under strict guidelines of quality and uniformity. All 0.1 cm-1 sensors are built and tested to be within 1% of their nominal cell factor. Actual cell factors are stamped on the sensor housing or cable. A choice of cell factor determination and certification is available. Ultrapure water resistivity applications benefit from the -R option, ultrapure water cell factor determination. Conductivity measurements and applications requiring USP23/24 compliance can specify the -S option, NIST traceable conductivity calibration and calibration certificate. Simply enter the geometrical cell factor and temperature cell factor into a calibrated 876CR or 870ITCR Transmitter, or 875CR Analyzer, and you have a fully calibrated measurement system.
