Frequently asked questions

What is the VIbrating Wire data acquisition?

The vibrating wire is a wireless data acquisition IoT device that collects data from vibrating wire signals and transmits them using long-range, low power radio communications

How does it work?

The data logger operates by connecting to one or more vibrating wire sensors. It transmits data via Worldsensing LoRa networks to a CMT Edge for local-access, single-network deployments. Data can also be transmitted via the internet from the gateway to CMT Cloud for a multi-project, multi network deployment.

What kind of sensors can I connect to the Vibrating Wire data logger?

The Vibrating Wire data logger can be connected to all vibrating wire sensors in the market . The data logger can read sensors working on the 0 to 3000 hz frequencies, which covers most all the geotechnical vibrating wire sensors available in the market.

How many sensors can I connect to the data logger?

The Vibrating Data logger comes in a 5-channel and 1-channel version so you can accommodate the necessary number of sensors, one per each channel.

If the device is battery operated, how long should I expect the batteries to last?

Loadsensing data loggers can have a battery lifespan of more than 25 years. The battery life will depend mainly on the reporting period selected, which periodicity in which data is reported from the data logger. Reporting periods range from 30s to 24 hours.

Is there an option to process data into engineering units?

Yes. Raw data sent from the node to CMT Cloud or CMT Edge can be processed using engineering formulas to get the appropriate magnitudes for data analysis.

What is the communication range for the data logger?

The radio range of any of Loadsensing devices varies depending on the environment. In open sight, the range can reach up to 15 km (9.3 mi), while in a city street it is up to 4 km (2.5 mi). When placed in a manhole in a city street, the range is up to 2 km (1.2 mi), and in a tunnel, it extends up to 4 km (2.5 mi).

Is the data logger surge-protected?

Yes, the data logger complies with IEC61000-4-5, Class 2, If higher class protection is required, external surge protection devices must be installed.

Would these data loggers work well when installed in manholes?

VW loggers have IP68 rating while ensuring a proper installation. Il installation best practices are followed, there is no problem no installed these loggers in manholes.
