Test system of temperature sensor

The invention discloses a test system of a temperature sensor. The test system comprises a computer, a thermoelectric couple and thermal resistance tester, and a temperature sensor test platform, wherein the computer is connected with the thermoelectric couple and the thermal resistance tester through a serial port line; the temperature sensor test platform comprises a plurality of sample fixture sockets, a plurality of ohm gauge measuring openings, a self-setting control key, a computer serial port and an ohm gauge communication serial port; the sample fixture sockets, the ohm gauge measuring openings, the self-setting control key and the ohm gauge communication serial port are respectively connected with the computer through serial port lines; the temperature sensor test platform works according to the following steps of: (1) powering on and detecting; (2) setting; (3) measuring; and (4) matching. According to the test system disclosed by the invention, a multi-position automatic switchover measurement of the samples is realized and the whole switchover and measurement process is automatic, so that the work efficiency is improved, the production cost is reduced and a test result is visual and precise.
