Thermoelectric metal sorter |
摘要 |
A metal sorter including a pair of electrically conductive probes of identical metallic composition are placed in contact with a metallic specimen. A thermoelectric heat pump is positioned between the two probes to produce a temperature difference therebetween, a temperature sensing device senses the temperature difference and provides an electric signal to control the electric power supplied to the heat pump. A detection device provides an electric signal indicative of the potential difference between the probes.
