The KDAQ200+ is the first in a new line of products that make it easier
to use analog sensor products with USB interfaces. The KDAQ200+ has
two high resolution differential AD inputs along with a thermocouple input for
reading the sensors and allowing the user to compensate for thermal effects on
the transducers. However, what puts the plus in the KDAQ200+ is
how it uses the USB power to derive a clean programmable +/-5V to +/-24V supply
voltage that can be used to power legacy sensor systems. Using the KDAQ200+ and
the supplied software, engineers can quickly connect up sensor systems and
begin logging data immediately. The KDAQ200+ essentially "USB
enables" analog transducer systems such that the power supply, data
acquisition, and logging functions are in a clean integrated package.
This allows engineers to use battery powered laptops and notebooks directly
with analog transducers with no need for external supplies to power
them. Because the supply can supply a bipolar voltage it can work
with many legacy transducers. The additional thermocouple input also
allows the user to evaluate and deal with environmental effects. There are
many USB data loggers and acquisition systems on the market. What makes
this product different is that it also acts as a programmable bipolar power
supply completely powered by the USB port. This allows an analog
transducer to truly become "USB enabled" where the unit is powered by the USB
port and data collected over the USB port. With notebook PC's becoming
ubiquitous it makes it easy and low cost to set up for data logging.
