Common polar net type multi-point thermocouple

Abstract

The invention discloses a common polar net type multi-point thermocouple in the technical field of thermocouples. The common polar net type multi-point thermocouple comprises a first thermocouple; thenegative pole of the first thermocouple is connected with the positive pole of each of a second thermocouple, a fifth thermocouple, a sixth thermocouple, a ninth thermocouple, a tenth thermocouple, athirteenth thermocouple and a fourteenth thermocouple. The common polar net type multi-point thermocouple is reasonable in design and high in practicability; the multiple thermocouples are connectedthrough a common polar net, so that a lot of materials are saved and the production cost is reduced; 16 points of measure can be obtained through 8 wiring terminals, so that a space of 24 wiring terminals can be saved when compared with the quantity of wiring terminals used in a traditional condition that 16 points of measure need 32 wiring terminals; and each corner of a temperature measurement field can be covered so that the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of thermocouples, in particular to a shared polar net type multi-point thermocouple. Background technique [0002] Thermocouple is equivalent to a kind of thermometer, which is mainly used in temperature monitoring and control in industrial production process. Since the birth of my country's first thermocouple in the 1960s, dozens of thermocouples have been developed successively. With the passage of time, technological innovation has improved, and a batch of multi-point thermocouples have been produced. This kind of multi-point thermocouple can be used for industrial Objects or positions in production are monitored at multiple points, but the current multi-point thermocouples need to use multiple thermocouples for assembly. Due to the defects of the wiring method, a large amount of thermocouples and wires are wasted, the production cost is high, and it is difficult for the measurement The temperature field c...
