- Features
[Supports fluorine liquids]
Supports fluorine liquids with excellent electrical insulation.
Fluids with low global warming potential are also supported.[Flow rate adjustment needle type added]
Fine adjustment is possible with the manual valve.[ATEX Directive added support]
Explosion-proof performance:Ⅱ 3G Ex ec ⅡC T4 Gc[Selectable output]
It can be switched among flow rate, temperature switch output, analog output and IO-Link communication (option).
It also supports switching between PNP and NPN.[Fluid temperature measuring function]
All models feature a fluid temperature measurement function as standard.
It can handle cold water to hot water of up to 95°C without the provision of a temperature sensor, improving the management level.[Wide flow rate range]
The detection range of the flow rate lower limit is expanded to support a wide flow range.[Flow rate adjustment mechanism]
The flow rate can be adjusted using the manual cock (option).[IO-Link]
IO-Link communication (option) enables remote control from the host as well as data collection.
