Transcription

1 Product Specifications 871C Series Contacting Conductivity and esistivity Sensors and ccessories PSS 6-3C2 The 871C 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. pplication 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 a Model 870ITC Intelligent Transmitter or a Model 875C Intelligent nalyzer. INTODUCTION The 871C Series Sensors measure the conductivity or resistivity of a solution. These sensors, together with an 870ITC Intelligent Electrochemical Transmitter or an 875C Intelligent Electrochemical nalyzer, 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. PPLICTION FLEXIILITY 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. NUMEOUS MTEIL SELECTIONS The 0.1 cm -1 cell factor sensors are concentric cylinders constructed with titanium or Monel electrodes. Titanium is highly corrosion resistant and is compatible with most fluids except acidic fluorides. For applications involving acidic fluorides, Monel electrodes are recommended. The 10 cm -1 cell factor sensors use graphite electrodes. choice of insulator materials and process connection materials permits chemical compatibility and ensures measurement integrity at elevated temperatures and pressures.

2 Page 2 QULITY ND UNIFOMITY 871C sensors are manufactured under strict guidelines of quality and uniformity. ll 0.1 cm -1 sensors are built and tested to be within 1% of their nominal cell factor. ctual cell factors are stamped on the sensor housing or cable. choice of cell factor determination and certification is available. Ultrapure water resistivity applications benefit from the - 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 870ITC Transmitter or 875C nalyzer, and you have a fully calibrated measurement system. PT1000 TD FO CCUTE TEMPETUE COMPENSTION ll 871C sensors incorporate a 1000 Ω, 3-wire TD integral temperature transducer whose signal is used by the transmitter for temperature compensation and measurement. The 0.1 cm -1 sensors offer a choice of accuracy associated with this device. The - cell factor selection utilizes a standard Class, 1000 Ω TD. This TD meets DIN requirements for Class accuracy; ±[ (T)] (where T = temperature in C). This selection can be used for conductivity and noncritical resistivity measurements. The - Cell factor selection utilizes a Class, 1000 Ω TD. This selection is recommended for all resistivity measurements and is required to obtain optimum system accuracy. This TD meets DIN requirements for Class accuracy; ±[0.15±0.002 (T)] (where T = temperature in C). Optimum positioning of these TDs within the inner electrode ensure close thermal contact with the process and minimal influence from ambient temperatures. Temperature cell factors (tcf) are determined utilizing NIST traceable techniques and are stamped on each 0.1 cm -1 cell factor sensor housing or cable. ESY TO INSTLL The sliding bore piece design permits installation without twisted cables. large selection of mounting hardware and accessories is offered to meet virtually all process requirements. This includes bushings in varying materials and sizes, flanges, sanitary fittings, flowcells, and ball valve assemblies.

9 SYSTEM CCUCY OF THE 870ITC TNSMITTE O N 875C NLYZE WITH N 871C-2XXXXXX- SENSO FO ESISTIVITY MESUEMENT The 870ITC Intelligent Transmitter or 875C Intelligent nalyzer, along with an 871C-2XXXXXX- Sensor, provide an advanced resistivity measurement system with significantly enhanced performance. The transmitter, or analyzer, and sensor provide exceptional stability and performance during measurement in pure and ultrapure water. Temperature compensated system accuracy has been found to be better than or equal to ±1.06% MS throughout the 20 to 60 C temperature range. ll variables cell factor calibration, design for increased transmitter and sensor accuracy, and calibration procedures have been refined for optimum performance. The premium resistivity sensors are manufactured of materials accepted in industries utilizing ultrapure water. They are available with increased insertion lengths and a larger profile to optimize representative measurement sampling. The 0.1 cm -1 cell factor sensors are manufactured to 1% tolerances and are precalibrated with an ultrapure water calibration factor determined at elevated temperatures to ± cm -1 accuracy. This elevated temperature high-purity water calibration has been determined to be the best method for an accurate cell constant calibration PSS 6-3C2 Page 9 because it reduces the sensitivity to impurities. The cell factor accuracy of 0.101% assumes published data for ultrapure water introduces negligible error. If experimental uncertainty in the published data is considered, the effective cell factor accuracy changes to ±0.270%, thereby impacting the system accuracy stated above. With the increased use of hot deionized water rinsing for wafer washing and other semiconductor applications, comes the need for higher performance temperature-compensated measurement. The combination of an 870ITC Intelligent Transmitter or 875C Intelligent nalyzer, along with an 871C-2XXXXXX- Sensor, meets this highperformance need. Figure 2 shows absolute resistivity vs. temperature curves for a range of water samples with salt to ultrapure water (18.16 MΩ cm). It should be noted that, as the temperature of water with trace impurities increases, the absolute resistivity of that water starts to converge to similar values for the various samples. lso, as the temperature increases, the relationship between resistivity and salt concentration becomes smaller; and calculation of the temperature-compensated value at 25 C becomes more demanding SOLUTE ESISTIVITY M cm* M cm* M cm* 5.00 M cm* 2.00 M cm* 0 *25 C Value TEMPETUE (C ) Figure 2. bsolute esistivity versus Temperature Curves

10 Page 10 SYSTEM CCUCY OF THE 870ITC TNSMITTE O N 875C NLYZE WITH N 871C-2XXXXXX- SENSO FO ESISTIVITY MESUEMENT (Cont.) To improve the temperature corrected resistivity measurement over an extended temperature range, the most important parameter to control is the accuracy of the temperature measurement. The 871C- Sensor incorporates a Class 1000 Ω Pt TD three-wire temperature transducer for temperature measurement optimization. Platinum TDs are known to be mechanically and electrically stable with accurately known thermal curves. In addition to an accurate transducer, highly accurate temperature measurements must also provide lead wire resistance compensation. The 871C Sensor family incorporates a three-wire resistance measurement (instead of a 2-wire) to minimize lead wire effects. The actual temperature calibration (tcf) of each cell s TD is known with an accuracy of ±0.03 C. The 870ITC Intelligent Transmitter and 875C Intelligent nalyzer are the newest members of the family of 870IT/875 Series of high performance intelligent transmitters and analyzers. factory default calibration is available for every measurement range selected and the transmitter has a choice of two pre-engineered resistivity specific temperature compensations available for ultrapure water (based upon published research). The measurement method used to make the absolute resistivity measurement is extremely important to achieve optimum results. The 870ITC and 875C use ac frequency and voltage drive for each to optimize the measurement range chosen. oth instruments have a stated accuracy of 0.1% of full scale chosen to operate and the temperature circuit has an accuracy of ±0.03 C. The two factory calibrations on the sensor (CF and tcf) are easily entered into the calibration menu of the transmitter for a total system calibration. Extended insertion lengths available to optimize representative sampling ohm Class Pt TD with 3-wire lead wire compensation. Specific temperature cell factor determined with 0.03 C accuracy. Driven shield minimizes effects of cable capacitance, thus providing maximum measurement stability. 0.1cm -1 cell factor sensor manufactured to 1% tolerances.
