Krohne SMARTPAT COND 1200, 3200 and 5200 conductivity sensors

Krohne has introduced three SMARTPAT sensors for conductive conductivity measurement in liquids: SMARTPAT COND 1200, 3200 and 5200.

SMARTPAT is a series of digital 2-wire loop powered sensors with integrated transmitter technology. SMARTPAT sensors can be connected directly to the process control system via 4–20 mA/HART 7 interface. They can be configured and calibrated offline via PACTware FDT/DTM, on-site with a HART handheld or an optional loop powered operating unit.

Targeted at the water and wastewater industries, the application area for SMARTPAT COND 1200  ranges from process monitoring in water treatment plants (industrial and drinking water), water quality/limit values monitoring and filter monitoring. It has a measuring range for cell constant c=1 of 100 µS/cm to 20 mS/cm.

SMARTPAT COND 3200  is aimed at quality measurements in condensate, cooling water and boiler feed water in power plants. It can also be used for reverse osmosis, monitoring of ion exchangers, deionisation or desalination processes, such as in semiconductor production. It has a measuring range for cell constant c=0.1 of 1–1000 µS/cm, and for  c=0.01, 0.05-10 µS/cm.

SMARTPAT COND 5200 has a measuring range for cell constant c=1 of 10 µS/cm to 15 mS/cm and is designed for use in separation processes (caustic solution/water) or process monitoring in water or wastewater treatment in chemical, petrochemical as well as in the water and wastewater industries.

Each SMARTPAT sensor is specifically designed for its area of application: approvals and certificates range from installation in hazardous areas up to Zone 0 to hygienic areas.
