RSSK Evaluation Results
The kit can be utilized to evaluate t he measureme nts
of thermocoup les, RTD, and strain gau ges, which
are typical sensors in industrial equip ment .
Our evaluatio n of K-ty pe thermocou ple s using the
RSSK shows that the measu red tempe rature error is
within ±0.6°C unde r environme nts betwe en -40°C
and 85°C and the ef fective resolu tion is 19.4 bit,
which means temperat ure dev iation is equivalent to
0.0015°C at rms value.
The measured tempe ratu re error, which is within the
sensor error, validates t he evaluat ion boa rd as a
reference design.
Our evaluation of load cell using the RSSK shows
that the measured weight error is within
±0.005%max.span and the effective resolution is
21.0 bit, which means weight deviation is equivalen t
to 4.8mg at rms value.
The measured weigh t error, which is within the
weight toleran ce, val idates t he evaluat ion boa rd as a
reference design.
Refer to applicat ion note s for more deta ils of each
sensor measurement evaluation.
