Monitoring hydraulic systems remotely

Third Quarter 2005 Hydraulic systems & components

The prevention of breakdowns, planning of maintenance activities, measurement of machine performance and the determination of operating trends - are all possible with Bosch Rexroth's concept called Trended.

Available from Hytec, the central data administration service is structured to specifically cater for recording system variables that influence the operating lifespan of components or system performance over an extended period. Using a data acquisition system sourcing the primary data from a machine via various sensors, a GSM network then carries regular updates to a base station for processing. Through a web-based user interface, users can thus access and monitor hydraulic systems no matter where they are located through a secure link. The system can be set to only capture abnormal information into the database if the user so chooses.

Apart from the advantages mentioned above, this system allows for operating costs to be optimised and gives users 24/7 access to a process from anywhere in the world. Typical examples of remote monitoring possibilities include oil temperatures, filter element condition, oil contamination levels, oil level, case pressure, suction pressure and operating time. While its focus is primarily on hydraulic systems, the variables for tracking overall machine performance can easily be added to the service. The system also allows for alarms to be generated when a customer defined condition is met.

Bosch Rexroth is confident that the obvious advantages in terms of breakdown prevention, predictive maintenance, production optimisation and remote monitoring and planning will see Trended establishing itself in factories around the world. The picture shows how users can access and monitor hydraulic systems no matter where they are located through a secure link to a web-based user interface.
