Yokogawa Conductivity Sensor SC8SG

General Specifications: 

Cable with pin terminals (applicable to FLXA21,SC202G and SC202SJ)

Cable with M3 ring terminals (applicable to SC450G,)

Cable with fork terminals (applicable to SC202G and SC202口/TB)

Cable with M4 ring terminals (applicable to FLXA21)

Object of measurement: Conductivity of liquids

Measuring Principle:  2-electrode system or 4-electrode system

Cell Constants:  0.01 cm-1   or 10 cm-1 (for two-electrode system)

                              10 cm-1   (for four-electrode system)

Temperature Range: 0˚ to 100˚C (130˚C maximum only for 0.01 cm-1   cell constant detectors, excluding those with polypropylene chambers)

Pressure:  1000 kPa max. (500 kPa maxi- mum for detectors with polypropy- lene chambers)

Flow rate of Sample Solution: No particular limitation applies, although a value of less than 20 l/ min. is recommended for flow- through detectors.

(Note) No limitation appliesto flow rate (flow velocity) as far as measurement is concerned. Take care, however, when usingflow-through detectors. Electrodes or the inner wallsof a liquid chamber may wear put drastically at higher flow speeds if a measured solution contains slurry. Air bubblesshould not be mixedin the sample solutions to obtain correct measured values.
