Wireless Data Acquisition

TEDIASENS SENSOR NODE external - SN-X

wireless synchronous data acquisition for external sensors
synchronous vibration via WLAN
pressure, temperature, rotation speed, acceleration measurement

Wireless synchronous data acquisition network for external sensors:
TEDIASENS SN-X is used to simultaneously sample up to 3 physical signals such as vibration and acceleration. The sensors are connected by means of BNC, LEMO, ... connectors and can be supplied with IEPE (ICP) excitation. The inputs can be coupled AC or DC and input range can be programmed to ± 1 V resp. ± 10 V. With a dynamic of 24bit, a signal to noise ratio of -109,5dB (RMS, broadband) and a maximum sampling rate of 13 kHz TEDIASENS SN-X can solve multiple measurement tasks without cable and minimal setup effort.
