This device converts the physical pressure of a medium (liquid or gas) into a standardized electrical signal. The “Digital” and “G” designation indicates it features a IO-Link communication interface, making it a key component for Industry 4.0 and smart factory applications, in addition to its standard analog output.
Typical Applications
The PE 7003 G 14 is versatile and used across many industries, including:
-
Industrial Automation & Machinery:Â Hydraulic and pneumatic pressure monitoring on machines, presses, and injection molding equipment.
-
Mobile Equipment:Â Monitoring hydraulic systems in construction and agricultural machinery.
-
Process Engineering:Â Monitoring filter clogging, pump pressure, and tank levels (via level calculation).
-
Coolant & Lubrication Systems:Â Ensuring proper pressure in cooling circuits.
