Get more information about digital communication capabilities and field bus systems for water and wastewater analytics.
At Hach® you will find information about the broad range of sensors and controller for process automation and the seamless integration into Process Control and Asset Management Systems.
Hach goes beyond the universally popular 0/4-20mA signal to provide the widest digital communication capability in the world of continuous sensors and controllers for water and wastewater analysis. These sensors help with secure and efficient operation of treatment plants. They can be integrated easily into common Process Control and SCADA systems.
Furthermore you will find information about the broad range of sensors and controller for process automation and the integration into Process Logic Control (PLC) and Asset Management Systems.
The following digital bus-systems are available:
