The customer suddenly requested that we take measures to address carbon neutrality as instructed by the parent company. We were conducting routine inspections of the mechanical power meters at multiple factory buildings, but due to a shortage of manpower, we were unable to meet the parent company's required standards. Therefore, we were in need of a systematic approach to power monitoring. In response, we proposed the "LoRa wireless device." For this power monitoring, using the Hakaru Plus power converter (TWPM) allows for complete retrofitting installation at the desired monitoring locations.

In the customer's factory, there are three boiler facilities, and abnormalities are confirmed through daily patrol inspections. However, the locations of the boiler facilities are far away and very difficult to access. The office cannot detect abnormalities, and the patrol inspections are often delayed in noticing them, so there was a request to be aware of and respond to abnormalities as they occur. Therefore, we proposed the "LoRa wireless device," which enables wireless transmission of contact signals. This allows the abnormal signals from the scattered equipment to be checked in the office, eliminating the need for patrol inspections solely to confirm the presence of abnormalities. [Case Overview] ■ Issues - The boiler facilities are located far away and are very difficult to access. - The office cannot detect abnormalities, and patrol inspections are often delayed in noticing them. ■ Request: To be aware of and respond to abnormalities as they occur. ■ Proposal: LoRa wireless device. *For more details, please refer to the PDF document or feel free to contact us.
