DATA LOGGER FOR CRACKMETER

Follow the evolution of cracks with our radio extensometer crack gauge

The advantages of the LGS31 data logger for crack gauges

POTENTIOMETRIC SENSOR INTERFACING
Data logger for extensometer, crackmeter or any potentiometric sensor
WIRELESS COMMUNICATING SENSOR
Ideal for deploying an outdoor wireless sensor network
DATA SECURITY
All your measurements are stored in the data logger then transmitted by radio to a PC or to the Newsteo Cloud

1 Choose the sensor that's right for you. Connect it to the recorder
2 The recorder transmits the recorded data by radio to the receiver: a PC equipped with the RF Monitor software or a Newsteo Gateway which downloads the measurements to a web application.
3 In the event of an anomaly, a notification is sent
4 You find all your data in the form of curves, graphs... and can export them whenever you want.
