Advantages of SDI-12
2.0 Advantages of SDI-12
A serial-digital interface is a logical choice for interfacing
microprocessor-based sensors with a data recorder. This has advantages
for sensors and data recorders.
- Unique and complex self calibration algorithms can be done
in microprocessor-based sensors.
- Sensors can be interchanged without reprogramming the data
recorder with calibration or other information.
- Power is supplied to sensors through the interface.
- Hybrid circuit and surface mount technologies make it practical
to include the power supply regulator, a microprocessor, and other
needed circuitry in small sensor packages.
- Sensors can use low cost EEPROMs (electrically erasable programmable
read only memory) for calibration coefficients and other information
instead of internal trimming operations.
- The use of a standard serial interface eliminates significant
complexity in the design of data recorders.
- Data recorders can be designed and produced independently
of future sensor development.
- SDI-12 data recorders interface with a variety of sensors.
- SDI-12 sensors interface with a variety of data recorders.
- Personnel trained in SDI-12 will have skills to work with
a variety of SDI-12 data recorders and SDI-12 sensors.
