Transmisión inalámbrica y sincrónica de datos de medición en vivo
Los sistemas TEDIASENS ofrecen una transmisión de datos de medición en directo basados en WLAN por radio a través de un punto de acceso a un PC. Si se utilizan varios nodos de radio TEDIASENS simultáneamente, pueden funcionar como una red de sensores inalámbricos con gran ancho de banda y registro de datos síncronos. La grabación de datos sincrónica hace de TEDIASENS un sustituto del cable, por así decirlo. Los sistemas se utilizan en aplicaciones de servicios móviles como el diagnóstico de máquinas y las mediciones de campo y de objetos. TEDIASENS está diseñado para las altas exigencias de las mediciones de vibración y aceleración con acelerómetros industriales. Los sensores de velocidad, desplazamiento, presión y flujo o los codificadores y barreras de luz pueden ser escaneados sincronizadamente con TEDIASENS. Los nodos del sensor se alimentan de una batería integrada. ¡Industria 4.0 para ir!

TEDIASENS-LN Series (Logging-Node)In addition to the TEDIASENS systems, which are used for synchronous live measurement data acquisition and are often used for short measurement times with online evaluation, ELOVIS develops customized LOGGING-NODE systems for long-term condition monitoring of machines or systems with radio connection. Depending on the type, LOGGING-NODE measurement systems are created with internal and external sensors for different measuring quantities. The measured data can be continuously or periodically monitored and recorded over several years. Selected measurement data, alarms or preprocessed signal characteristics are transmitted by radio to a gateway, which provides the data to the network. Compared to wired condition monitoring systems, the LOGGING-NODE systems offer the following advantages:
