Wireless Data Transmission and Wireless Vibration Measurement

Synchronous wireless data transfer via wireless network, wireless measurement of vibration and oscillation.

When troubleshooting complex objects (machines, buildings, structures, …), the measurement of vibrations, speeds, temperatures, pressures or other measured variables must often be carried out quickly and easily at different measuring points simultaneously. Laying sensor cables is the most time-consuming part of the measurement campaign and can take longer than the measurement itself in many cases. In some measuring applications, however, cables may interfere with the measurement, or cables can only be laid after the machine has been switched off due to moving machine parts. If the measuring point itself moves or rotates, sensors with cables cannot be used. … ELOVIS TEDIASENS sensor nodes type SN-I (Sensor-Node-Internal) are equipped with a 3-axis accelerometer, a rechargeable battery and a radio module. The radio nodes without integrated accelerometer are called SN-X (Sensor-Node-Extermal) and have instead 3 BNC sockets for the connection of various commercially available sensors. Both radio nodes are small and powerful. The radio nodes can transmit measurements over 9 hours in continuous operation. Typical radio distances are 20m to 100m. Up to 40 radio nodes, each with 3 channels can be operated simultaneously.
