Smartpat conductivity ­sensors for water ­applications

December 2015 Sensors & Transducers

Extending its portfolio of process analysis sensors and systems, Krohne has introduced three new Smartpat sensors for conductivity measurement in liquids: Smartpat Cond 1200, 3200 and 5200.

Introduced in 2013, Smartpat is a series of digital 2-wire loop powered sensors with integrated transmitter technology. Using a VP cable, any Smartpat sensor can be connected directly to the process control system via 4-20 mA/HART 7 interface. This offers advantages in both handling and costs of a measuring point. An additional transmitter on site is no longer necessary, Smartpat sensors can be configured and calibrated offline via PACTware FDT/DTM, or onsite 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 (measuring range for cell constant c=1: 100 μS/cm – 20 mS/cm) ranges from process monitoring/control in water treatment plants (industrial and drinking water), water quality/limit values monitoring, to filter monitoring.

Smartpat Cond 3200 (measuring range for cell constants c=0.1: 1 – 1000 μS/cm, c=0.01: 0.05 – 10 μS/cm) is aimed at quality measurement in condensate, cooling water, boiler feed water in power plants. Also, it can be used for reverse osmosis, monitoring of ion exchangers, deionisation or desalination processes, e.g. in semiconductor production.

Smartpat Cond 5200 (measuring range for cell constant c=1: 10 μS/cm – 15 mS/cm) is designed for use e.g. in separation processes (caustic solution/water) or process monitoring in water or wastewater treatment in chemical, petrochemical as well as in 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. Along with the sensor family, KROHNE offers a large portfolio of accessories, including loop powered indicators, USB interface cables, junction boxes, operating units, standard solutions and mounting assemblies.
