THERMOCOUPLE_MULTIPLEXER
Under control of logic input, DG509 four-channel differential analog multiplexer connects selected one of four thermocouples to instrumentation amplifier driving digital or other readout. To de- room temperature, but this arrangement will be couple sensors from instrumentation amplifier, sensitive to changes in a mbient temperature.-reference junction at 0'0 can be used as shown. Analog Switches and Their Applications, Sil-Altematively, bucking voltage can be set at iconix, Santa Clara, CA, 1976, p 7-77-7-78.
