SC202 2-Wire Conductivity/Resistivity Analyzer

Product catalog summary

Overview: The document details the specifications and features of the Yokogawa SC202 two-wire conductivity/resistivity analyzers, designed for precise measurements in industrial environments such as semiconductor and pharmaceutical industries.

Transmission Signal: The SC202 provides a 4-20 mA DC isolated output, selectable for either conductivity or resistivity measurements.

Performance Specifications:

Conductivity: Ranges from 2 µS x K cm^-1 to 200 mS x K cm^-1 with a linearity and repeatability of ±0.5%FS. Lower ranges (1 µS x K cm^-1 to 2 µS x K cm^-1) have an accuracy of ±1%FS.
Resistivity: Ranges from 0.005 kΩ / K cm^-1 to 1 MΩ / K cm^-1 with similar accuracy.
Temperature: Sensors (Pt1000, PB36 NTC, Ni100) provide accuracy within ±0.3°C to ±1°C depending on the sensor type.

Temperature Compensation: Utilizes NaCl tables and matrix compensation with tolerances of ±1°C and ±3°C respectively.

Power Supply: The SC202G model supports up to 40 V DC, while the SC202SJ model supports up to 31.5 V DC.

Input Specifications: Supports two- or four-electrode measurements with cell constants ranging from 0.008 to 50.0 cm^-1.

Measuring Range:

Conductivity: 0 µS/cm to 200 mS x (Cell constant), with overrange up to 1999 mS/cm.
Resistivity: 0.005 kΩ / (Cell constant) to 999 MΩ·cm.
Temperature: Ranges vary by sensor type, with Pt1000 supporting -20 to 250°C.

Display: Features a liquid crystal display with main and message displays, including warning flags and units.

Additional Features:

Line-segment linearized output function for accurate measurement across different concentrations.
Preprogrammed and user-programmable matrices for temperature compensation.
Compliance with USP <645> for pure water monitoring.

Applications: Suitable for ultrapure water requirements in semiconductor and pharmaceutical markets, as well as traditional water quality measurements in power plants and chemical applications.

Specifications: The document outlines specifications for conductivity transmitters, including options for intrinsically safe and non-explosionproof types, and details materials such as stainless steel and carbon steel for components.

Procedures and Certifications: Mentions TIIS Certification, an explosion approval from the Technology Institution of Industrial Safety, specifying that the SC202SJ model is available only in Japan, South Korea, Taiwan, China, and Russia.

Technical Parameters: The resistivity range is specified with a minimum span of 0.001kΩ·cm and a maximum span of 999MΩ·cm, with a maximum of 90% zero suppression.

Materials and Coatings: Components are available in stainless steel and carbon steel, with options for epoxy baked finishes and SUS screws with Teflon coating for salt protection.

Contact Information: Provides contact details for Yokogawa Electric Corporation's headquarters and regional offices globally.

Key Options and Codes: Lists various option codes corresponding to different configurations and features of the transmitters.
