Space Temperature Averaging

Space temperature averaging is accomplished by wiring a number of remote sensors in a series/parallel circuit.

Using the BAYSENS016* or BAYSENS017*, at least four sensors are required to accomplish space temperature averaging. Example #1 illustrates two series circuits with two sensors in each circiut wired in parallel. The square of any number of remote sensors is required. Example #2 illustrates three sensors squared in a series/parallel circuit. Using BAYSENS032*, two sensors are required to accomplish space temperature averaging. Example #3 illustrates the circuit required for this senor. Table 4 lists the temperature versus resistance coefficient for all sensing.
