Applications
Averaging Sensing
Series-parallel wiring arrangements of four (2 x 2), nine
(3 x 3), sixteen (4 x 4), or more sensors provide an
average temperature reading in an area or large duct
when one sensor cannot provide a representative
reading. (See Figure 4.)
A series-parallel arrangement requires the same
number of parallel-connected sensors as there are
series-connected sensors. For example:
• with four sensors, connect two parallel legs with
two sensors in series in each leg
• with nine sensors, connect three parallel legs with
three sensors in series in each leg
Note: All sensors in a series-parallel network must be
of the same sensor type and value. For example, use
all 100 ohm platinum or all 1k ohm nickel sensors.
