Features
The compact type 528 pressure transmitter is based upon the well proven ceramic technology developed by Huba Control over 20 years ago. Huba Control offers with the Type 528 a universally applicable pressure transmitter with IO-Link communication technology. IO-Link is a standardized, digital point-to-point connection that allows the user to easily wire the unit and access a wide range of specific device and process data. IO-Link offers numerous possibilities for device diagnostics, allowing the status of the pressure transmitter to be continuously monitored. This makes the 528 IO-Link the ideal pressure transmitter for your Industry 4.0 application.
• Compact, rugged construction
• Communication via IO-Link 1.1 (Smart Sensor Profile ED2)
• Sensor diagnosis function
• High flexibility of process connections
