Applications

Explore the wide range of monitoring solutions the Analog Data Logger enables across geotechnical, structural, environmental and remote process monitoring.

Geotechnical

Structural

Environmental

Remote process

Pore water pressure & level

Piezometer Multi-point piezometer

Connect piezometers and multi-point piezometers from all the major geotechnical sensor manufacturers. Use 1-channel or 5-channel Vibrating Wire data loggers to transmit data from any number of sensor configurations. Water level sensors can be connected through Analog or Digital data loggers.

Soil water tension & moisture

Tensiometer Soil moisture sensor Granular matrix sensor

Assess soil water tension and moisture with a tensiometer and a granular matrix sensor both connected to an Analog data logger. Additionally, measure volumetric water content with a soil moisture sensor connected to a Piconode. You can also connect the Digital date logger to one or a chain of digital tensiometers.

Settlement & heave

Tiltmeter Liquid settlement system Tilt beam

Monitor settlement, heave and building response to tunneling and excavation with a liquid level settlement system connected to the Analog or the Digital data logger. Alternatively, you can use the Tiltmeter attached to a rigid beam and installed in a chain.

Specific weather parameters

Thermistor RH probe Pressure sensor Pyranometer Piconode Weather Kit

Read specific weather parameters like temperature, relative humidity, pressure or radiation through specific analog output sensors with the Analog data logger or the Piconode.

For a connect-and-collect experience, the Piconode Weather Kit offers a compact alternative. Multiple configurations are readily available, including temperature, relative humidity and rain gauge, to stream the right data to your information systems.

Open channel flow & pond level monitoring

V-notch Level sensor Vibrating wire weir

Different sensors compatible with Worldsensing data loggers can monitor flow in open channels and seepage collection ditches. For instance, non-contact level sensors using radar or ultrasonic technology can connect to the Analog data logger. Additionally, a vibrating wire weir monitor and a V-notch can measure flow in an open channel using a Vibrating Wire 1-channel data logger. Some of these sensors are also suitable for monitoring tailings pond levels.

Diesel fuel levels

Level sensor

Monitor diesel fuel levels with a fuel tank level sensor connected to an Analog data logger.

Cross-crack movements

Laser Tiltmeter Crackmeter Wireline extensometer

Detect slope movements by monitoring tension cracks across landslides using a displacement sensor compatible with Worldsensing’s Analog or Vibrating Wire data logger. For situations with large movements anticipated, wireline extensometers, draw wire sensors, or the Laser Tiltmeter can be suitable alternatives.

Loads & movement in beadings and joints

Pressure transducer Crackmeter Extensometer

Monitor the pot bearing pressure and displacement through pressure sensors, extensometers or crackmeters. Control the joint expansions and contractions wirelessly connecting these sensors to Analog, Digital or Vibrating Wire data loggers.

Frequently asked questions

What is the Analog Data Logger?

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

How does it work?

The analog data logger operates by connecting to a specific analog sensor using any of its four different channels. It transmits data via Worldsensing LoRa networks to a CMT Edge for local-access, single-network deployments. Data can also be transmitted via internet from the gateway to CMT Cloud for a multi-project, multi network deployment.

What is the maximum interval at which data can be collected?

Devices can be configured at different reporting periods. The highest possible acquisition rate when using Worldsensing is one sample every 30 seconds, and the lowest is one sample every 24 hours. With such parameters the system can run for a long period, between 7 and 10 years.

What is the communication range for the Analog 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).

What are the maintenance and troubleshooting requirements for the Analog Data Logger? Can it be handled by skilled employees internally?

Maintenance is straightforward and varies by location. With basic training, employees can configure and maintain the devices and gateway via the Worldsensing App. Monthly visual inspections are recommended, especially in active areas. Inspect devices and sensor cables if you notice anomalous or missing readings. Our remote management software reduces manual checks by allowing 24/7 access to network status and sending downtime alerts. Batteries can last up to 10 years, but it’s best to schedule changes based on battery life estimates and data acquisition frequency.

How is the data protected during transmission?

Data protection and privacy are achieved through 128 AES [Advanced Encryption Standard] encryption on multiple levels, for all data being sent from the sensors to the application server and back.

What they say about us

Discover how Worldsensing has made a positive impact, providing reliable solutions and exceptional support.

An important point in the project was the concrete anti-vandalism protection used to guarantee the safety of the equipment. Even with this protection, the system managed to transmit to the gateway more than 2 kilometers away. Read success story

Rodrigo Raposo
Geotechnical Engineer, D.Sc and Consultant, RD&I, 3Geo Tecnologia

In spite of being installed in boreholes with steel covers, or behind the body of the dam with no line of sight to the gateway, the Worldsensing nodes are able to transmit data without the need for repeaters. Read success story

Ludek Novosad
Senior Instrumentation Engineer, Geomonitoring

Worldsensing products are very easy to use. We can connect any type of sensor: strain gauges, extensometers, piezometers… we often install simultaneously with other trades on site, being able to connect to the logger in just a few minutes saves the customer time and money. Read success story


Geomotion Australia

One of the Worldsensing gateways that we first installed has kept on monitoring for years, without any work done on it. I haven’t had to check that gateway since I installed it. This kind of reliability is one of the biggest advantages of this system. Read success story

Rodrigo Vicencio
Chief Operating Officer, Geosinergia

We haven’t had to change the batteries yet. The Worldsensing devices in our project draw very little power and vibrating wire piezometers also require little power compared to other instruments. We expect the solution to easily have a 10-year battery life. Read success story

Vincent Le Borgne
Mining R&D Manager, GEO-Instruments Canada (formerly GKM Consultants)

In the past, we would have done it with cables. It would have been a lot of work for the construction company. It’s not really competitive anymore to use cable systems in geotechnical projects. Read success story
