Compressed air utilization
The networked measuring case
Kaeser Kompressoren - a manufacturer of compressed air products - has connected the first 400 of around 4,000 service cases to the cloud with the help of T-Systems.
The cases contain special measuring devices that the company's technicians use to carry out an analysis of compressed air utilization at the customer's premises in order to optimise the energy consumption of the compressed air system. These cases now report their location at regular intervals. This allows Kaeser to track where the expensive measuring devices are at all times. The company also monitors the battery status via the Cloud of Things dashboard, ensuring that only cases with charged measuring devices are used. Previously, it was sometimes difficult for the company to track the exact location and condition of the cases, as the technicians connect the measuring devices to the machines over a period of at least ten days in order to obtain a detailed picture of the customer's actual compressed air requirements and the utilization of the compressors. Some cases were difficult to find or completely lost. Now, each case reports its current location to the IoT platform. Deutsche Telekom's IoT package includes a cloud platform, sensors, connectivity and security for networking the service cases. Both companies are planning to further expand their IoT service in the future: Individual machines can also be networked with the cloud. The measured values are recorded, evaluated in the cloud and displayed on a dashboard. Together with SAP applications, compressor faults can be detected at an early stage and rectified before failures occur.
