Wireless, synchronous Live Measurement Data Transmission
TEDIASENS systems provide a WLAN-based live measurement data transmission via wireless access point to a PC. If several TEDIASENS radio nodes are in use at the same time, they can be operated as a wireless sensor network with high bandwidth and synchronicity of the data recording. Thanks to synchronous data recording, TEDIASENS is virtually a cable replacement. The systems are used in portable service applications such as machine diagnostics as well as field and object measurements. TEDIASENS is designed to meet the high demands of vibration measurement and acceleration measurement with industrial accelerometers. Speed, displacement, pressure, flow sensors or rotary encoder sensors and light barriers can also be transmitted synchronously by TEDIASENS. The power supply of the sensor nodes takes place via an integrated battery. This is industry 4.0 to go!

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:
