The measurement of specific conductivity in aqueous
solutions is becoming increasingly important for the determination
of impurities in water or the concentration measurement of
dissolved chemicals. The accuracy of the measurement is strongly
influenced by temperature variations, polarisation effects at the
surface of the contacting electrodes, cable capacitances, etc.
Yokogawa provides sensors for pure water systems, general
applications with a 2-electrode design and applications involving
high concentrations of chemicals with a 4-electrode design.
To install conductivity sensors in a permanent or semi-permanent
location, Yokogama offers wide a range of flow and immersion
fittings. A high degree of standardisation simplifies mounting,
servicing and removal or replacement of the sensors.
Included are flow fittings and subassemblies for
in-line or direct mounting of conductivity sensors in piping
systems.
The immersion fittings are designed for tanks, open vessels or
drains. PVC and stainless steel construction materials suit most
process conditions, regarding chemical resistance, pressure and
temperature specifications.
The fiitings of stainless steel might be used in sanitary
applications.
FEATURES
- Wide range of sensors to suit most process conditions.
- High precision of the cell constant (Field calibration not
necessary).
- Sensors for ultra-pure water applications.
- Built-in resistance thermometers Pt 1000 for automatic
temperature compensation.
- Optional material certificate 3.1 B according to EN-10-24
(DIN50049) for stainless steel sensors.
- Optional quality inspection certificate.
