Front line evolution in fluid condition monitoring with CME-AU2000

HYDAC’s CM Expert provides a complete fluid condition monitoring package solution for hydraulic and lubrication systems.

The latest version, the CME-AU2000, collects and stores reliable data to offer constant monitoring of fluid health and system integrity; and offers a range of connectivity and accessibility options including expanded I/Os, SCADA integration and SMS/email alarming.

This is achieved through a combination of a range of smart fluid sensors, a central data collection system, Edge computing, and MindSphere© data analytics.

In terms of fluid health parameters, every CME-AU 2000 offers the base capability of monitoring the following parameters:

• Solid particle contamination cleanliness class (ISO 4406)
• Water saturation (%)
• Dielectric constant
• Temperature

System connectivity spans levels

System connectivity options include Level 1, 2 and 3.

Level 1

Level 1, focused on oil analysis, has been designed as a base module to allow integration of condition monitoring easily into the system.

Level 1 includes the following:

• Local accessibility
• Ethernet connectivity
• Wi-Fi monitoring
• On board monitoring and data storage
• Possible integration to SCADA systems

Level 2

Level 2 comes with a central data collection system that monitors itself, automatically interprets data and points out corrective action before problems arise.

Level 2 includes the following:

• All Level 1 features
• Larger IO capacity
• Cloud accessibility
• 3G/4G/Wi-Fi capable (onboard modem/router)
• Local configuration with any device with an internet browser and Wi-Fi
• Data storage via Siemens Mindsphere cloud online portal
• Customisable dashboard
• Active alarming via SMS and emails

Level 3

• Any custom solution which can include all Level 2 features tailored specifically for customer requirements
• Potential to integrate PLC for automated functions, control, and larger IO requirements

HYDAC’s oil condition monitoring Level 1 unit also enables the client to leverage on the Level 2 solution. This means that if a customer has 10 machines in one factory, they don’t need 10 Level 2 units.

The customer can have nine Level 1s, which are cheaper, and bridge them together to one master Level 2 or Level 3 unit depending on the desired outcome.

Level 3 gives a programmable logic controller (PLC) at a local level to allow added control.

For systems requiring condition monitoring of parameters unrelated to fluid health, an Internet of Things (IoT) box is available as a standalone system to monitor and report any data inputs.

For example, HYDAC has applied this technology to monitor driver behaviour on board mining vehicles.

“In effect the CME-AU2000 enables the user to accurately monitor system health in real time and receive early warning signals of potential issues and thus gain the ability to make critically time-sensitive decisions to manually intervene or automate processes to perform maintenance to avoid costly unplanned breakdowns,” concludes HYDAC Engineer Robert Huang.
