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 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. Ta bl e 5 lists the temperature versus resistance coefficient for all sensing.
