KROHNE Introduces 2-Wire Loop Powered Operating Device

With SMARTMAC 200 W, KROHNE introduces a 2-wire loop powered operating device with HART 7 communication to the SMARTPAT series. The target industries for SMARTMAC include all industries that use SMARTPAT sensors or accessories: the chemical, petrochemical, pharmaceutical and food & beverage sectors as well as power plants, semiconductor and water/wastewater applications.

SMARTPAT is a series of process analytical technology, its highlight are the process analysis sensors with integrated transmitter technology: each sensor is directly connected to the process control system via 4…20 mA/HART without the use of an external transmitter. Nevertheless, there is still a demand for a convenient operating device on site. Therefore, SMARTMAC 200 W was developed as an optional 2-wire loop-powered operating device.

With SMARTMAC 200 W, SMARTPAT sensors can be read, calibrated and configured “online” at the measuring point. It features HART 7 communication and shows clear and configurable diagnostics according to NAMUR NE 107. With the replacement function, the connected SMARTPAT sensor can easily be exchanged as all sensor settings can be copied for the new sensor, including 4…20 mA parameter and TAG identification.

For convenient use, SMARTMAC 200 W features English, German, French, Spanish and Italian as operating languages. The die-cast aluminum housing (identical to IFC 100 W and MAC 100 W signal converters) offers ingress protection rating IP66/ IP67 (acc. to NEMA 4/4X).
