LOGGING-NODE – Wireless long-term Measurement Data Acquisition OEM

LOGGING-NODE systems are designed exclusively for the OEM market. LOGGING-NODE measurement systems are used for wireless long-term measurement data acquisition and are created, depending on the LOGGING-NODE type, with internal or external sensors for different measurement quantities and according to customer specifications. The system concept is selected so that measurement data can be monitored and recorded continuously or periodically over several years, if desired. Selected measurement data, alarms or preprocessed signal characteristics are transmitted by radio to a gateway, which provides the data accordingly. Compared to wired condition monitoring systems, the LOGGING-NODE systems offer numerous advantages: Easy to retrofit; Self-sufficient operation; Extremely small design; Minimal energy consumption; Operation with and without gateway possible; Customized design of the LOGGING-NODE system; Industry 4.0 to go for the machine/object to be monitored.
