Description

A kind of split type thermometric special electric thermo-couple

Technical field

This utility model relates to area of thermocouples, a kind of split type thermometric special electric thermo-couple.

Background technology

Traditional thermocouple be two thermometric silks are wrapped in same armouring body in become one structure formula, during use, One end welding of integrative-structure, when welding ends produces the temperature difference with the other end, will produce electromotive force, its electromotive force size in loop Proportional with the temperature difference, it is converted into temperature value according to Seebeck coefficient by the amplification of secondary meter signal and shows, reach thermometric Purpose, crucial one is one end welding here, and technology is required the highest by this mode, and solder technology can affect use not, and Expanding with heat and contract with cold for a long time and wear and tear, pad has disconnection danger

The most traditional thermocouple inner core overstriking, thermal response time is oversize, it is impossible to complete thermometric, inner core at short notice Carefully, thermal response time is much of that, and abrasion is too big, and the life-span is the shortest.

Utility model content the purpose of this utility model is to provide a kind of split type thermometric special electric thermo-couple, existing to solve Problem with the presence of technology.

In order to achieve the above object, the technical scheme that this utility model is used is:

A kind of split type thermometric special electric thermo-couple, includes the thermometric inner core of two different metal materials, it is characterised in that: Be respectively coated by a floor height temperature stainless steel tube oversheath outside two thermometric inner cores, high temperature stainless steel pipe oversheath and thermometric inner core it Between be also filled with mineral insulation magnesia powder；The two ends of two thermometric inner cores are stretched out outside high temperature stainless steel pipe oversheath respectively；Institute Stating stretching out of two thermometric inner cores and form the fixing silk tooth of connection on head end respectively, corresponding protects outside two high temperature stainless steel pipes The fixing silk tooth of connection is formed the most respectively on the head end of set；Described two thermometric inner cores wherein stretch out formation at end on one Thermometric rectifies pole, and the end of an other thermometric inner core stretches out formation thermometric end negative pole.

Scheme of the present utility model is that two thermometric inner cores are made two independent armourings, namely every armourings respectively An interior only thermometric inner core, but inner core is different material, in use, respectively by the inner core thermometric end of two armourings and gold Belonging to contact, the other end is connected into secondary meter displays temperature by compensating wire, does not has pad, forms loop by metallic conduction Electromotive force.

This utility model is applicable to measure metal solid surface temperature, automatically controls thermometric for assembly line work.

The beneficial effects of the utility model are:

1, temperature sensing material directly contacts with metal inside surface because contact point is little, thermal response time short can moment anti- Answer temperature；

2, service life is long, because two metal thermometric silks of old-fashioned thermocouple are in same armouring body, the most frequently Expand with heat and contract with cold and wear and tear, pad have disconnection danger；

3, traditional thermocouple inner core overstriking, thermal response time is oversize, it is impossible to complete thermometric at short notice, and inner core is thin, Thermal response time is much of that, and abrasion is too big, and the life-span is the shortest, and this utility model can integrate both advantages.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Shown in Figure 1, a kind of split type thermometric special electric thermo-couple, include the thermometric inner core of two different metal materials 1 and 2, it is respectively coated by a floor height temperature stainless steel tube oversheath 3 and 4 outside two thermometric inner cores 1 and 2, has protected outside high temperature stainless steel pipe It is also filled with mineral insulation magnesia powder 5 and 6 between set and thermometric inner core；Height is stretched out at the two ends of two thermometric inner cores 1 and 2 respectively Outside temperature stainless steel tube oversheath 3 and 4；Stretching out of described two thermometric inner cores 1 and 2 forms the fixing silk tooth of connection respectively on head end 7, corresponding forms the fixing silk tooth 8 of connection on the head end of two high temperature stainless steel pipe oversheaths 3 and 4 the most respectively；Described two Wherein the stretching out formation thermometric at end on one and rectify pole 9 of root thermometric inner core 1 and 2, the end of an other thermometric inner core is stretched Go out to be formed thermometric end negative pole 10.

In use, respectively the thermometric end 9 of two thermometric inner cores 1 with 2 is contacted with metal with 10, and the other end is by compensating Wire connects into secondary meter displays temperature, does not has pad, forms loop electromotive force by metallic conduction.
