Air consumption measurement for robots

Requirement
Compressed air is one of the most important types of energy. Even smallest leaks can lead to high costs in the course of time. Compressed air losses in a robot cell with different tools are to be minimised. The compressed air supply consists of two compressed air circuits (6 and 12 bar), which are to be monitored separately. In case of compressed air losses, an error message is to be sent to the maintenance staff.

Implementation
In both compressed air lines, compressed air meters of the type SD8000 are installed. They continuously monitor the compressed air consumption - during production as well as in quiescent condition. There are limit values for both operating states. An error message is generated when the limits are exceeded.

Customer benefits
Not only the energy costs could be reduced by monitoring the compressed air. The purchase of another compressor was no longer necessary and an existing compressor could be switched to standby. Installation and purchase of the compressed air meter is paid off in no time.
