The webinar provides an overview of the fundamentals of digital instrumentation, focusing on the complete signal chain from transducer to data acquisition.

It explains the role of electrical conditioning, analog-to-digital conversion, and microcontroller-based digital processing in ensuring accuracy and stability of measurements.

Particular attention is given to digital data transmission, with an emphasis on wired communication, physical layers, and protocol design. 

The RS485 physical layer and the Modbus RTU protocol are described as robust and widely adopted solutions for industrial and geotechnical monitoring. Practical aspects such as termination resistance, grounding, and network topology are discussed to highlight their impact on system reliability.

The presentation also introduces Sisgeo’s digital instruments, detailing factory configuration, diagnostics, and automatic logger integration.
