Product overview

Cautus Logger 3, CL3, is a further development of the CL1 logger and a new generation of smart IoT data logger.

CL3 has been developed based on our long experience and use of sensors in geomonitoring. CL3 is designed for easy installation, long battery life and integration with Cautus Web. With CL3, you have a complete solution for logging and secure transfer of data to the Cautus Web cloud solution. The logger comes with an internal battery and a robust IP66 enclosure.


The CL3 has very low power consumption and is equipped with an internal battery that provides a theoretical lifetime of over 10 years. The internal battery also makes the logger incredibly compact, external dimensions are 150x130x90 mm. The logger comes with a mounting bracket.

Due to the logger's compact size, robust casing and long battery life, the logger will be particularly suitable in places where space is limited, there is no access to an external power source, difficult access or difficult access for servicing.

The logger has the option of connecting up to three sensors, with either 4-20mA or vibrating wire (VW) sensor technology. Measurement data is sent using NB-IoT or LTE technology. CL3 has 2-way communication with the cloud solution Cautus Web. Measurement data is presented in Cautus Web.

The logger is particularly well suited to projects with Cautus Geos' preload pressure and water level sensors. With a built-in barometer, it will be able to correct data from sensors that measure absolute pressure.
