An SDI-12 interface provides connection points for smart sensors that operate according to the SDI-12 standard (Serial Digital Interface at 1200 baud). One or more SDI-12 sensors can be connected to a measurement or data acquisition system via plug-in terminals.
Features of the SDI-12 Standard
SDI-12 is a serial digital protocol designed specifically for low-power sensors with relatively low data rates, such as those used in environmental and process measurements. Multiple sensors share a common data line, through which they can be addressed and transmit measured values or status information to the host device.
Practical Application in Delphin
In Delphin measurement and data acquisition systems, SDI-12 interfaces with plug-in terminals are used to directly integrate compatible smart sensors. The measured values are then scaled, stored, and visualized within the device or the associated software, and used for analysis or monitoring tasks.
