Wireless, synchronous Live Measurement Data Transmission with IEPE Connection
TEDIASENS SN-X is a three-channel radio node suitable for connecting sensors supplied by the radio node to IEPE. It can thus be connected to any three sensors (for example for 3D acceleration measurement, pressure measurement, temperature or transmission measurement). The sensors can be connected to the sensor nodes via BNC connectors and can be fed in accordance with IEPE. Similarly, the inputs can be coupled either AC or DC. The input voltage range can be programmed to ± 1V or ± 10V. With a dynamic range of 24 bits and an SNR of – 109.5 dB RMS and a maximum sampling rate of 13 kHz, avoiding cables can solve a multitude of measuring tasks without a great deal of installation work. Applications for SN-X radio nodes are: Wireless synchronous detection of vibration, oscillation, acceleration, speed, pressure, temperature and acoustic signals.
TEDIASENS SN-XSensor nodes of type SN-X (sensor node) provide 3 BNC sockets for connection of external sensors. The SN-X are identical to SN-I radio nodes, except for:
