Chemical assembly and petroleum refineries will usually apply computers for logging and absolute testing the abounding temperatures associated with a process, about calculation in the hundreds. For such cases a cardinal of thermocouple leads will be brought to a accepted advertence block (a ample block of copper) absolute the additional thermocouple of anniversary circuit. The temperature of the block is in about-face abstinent by a thermistor. Simple computations are acclimated to actuate the temperature at anniversary abstinent location.
