Abstract
The utility model discloses an armored thermocouple with the function of outputting multiple singles in the same measuring point, which comprises a housing. A conducting wire group in the housing comprises a positive wire and a negative wire; a thermocouple hot end is arranged at the joint between the positive wire and the negative wire which are close to the temperature-measuring position; filleris arranged in the housing; and more than two conducting wire groups are arranged in the housing. Through the adoption of the scheme, in the armored thermocouple with the function of outputting multiple singles in the same measuring point, since the more than two conducting wire groups are packaged in the housing, that is, more than two thermocouple hot ends are provided, multiple signals are output in the same measuring point; and meanwhile, the utility model has the advantages of convenient installation and use, small volume, pressure resistance, vibration resistance, more than 50m length,separation of multi-path output singles, and strong anti-interference performance.
Description
Technical field
The utility model relates to a kind of thermopair, and a kind of armoured thermocouple with the many signal outputs of measuring point of more specifically saying so belongs to the temperature instrument Instrument technology field.
Background technology
Thermopair is the temperature measuring device of making according to Seebeck effect, promptly utilizes the homogeneous conductor of two kinds of heterogeneities to form the loop, when there is the temperature difference in two ends, produces the principle of thermoelectrical potential.Because it has simple structure, the Applicable temperature scope is wide, measuring accuracy is high, easy to use, bear heat, characteristics such as the physical shock ability is strong and response speed is fast, become one of industrial the most frequently used detector unit.
Along with science and technology development, the thermometric in some places requires the while multichannel to export to a plurality of systems at the temperature signal of same point for measuring temperature, to satisfy indication on the spot, far shows, long-range and computer automation is controlled, and warning of security against fire command centre and supervision etc. need.Existing often use a few Zhi Danzhi armoured thermocouples simultaneously with what measuring point obtained a plurality of temperature signals, a few Zhi Danzhi armoured thermocouples are installed in by binding to be tied up on the support.Obtain temperature signal simultaneously though this method can satisfy multichannel, exist binding that inconvenience is installed, bulky, withstand voltage poor, length should not deficiencies such as oversize (being generally less than 10m).
The utility model content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides the armoured thermocouple of the many signal outputs of a kind of same measuring point easy to install, performances such as volume is little, it is withstand voltage to have, antivibration, and its length can reach more than the 50m, and the multichannel output signal is isolated mutually, strong interference immunity.
For achieving the above object, the utility model is by the following technical solutions: a kind of armoured thermocouple with the many signals outputs of measuring point, it comprises housing, lead group in housing, described lead group comprises that a positive wire, cathode conductor, a positive wire of described lead group and the junction of a close temperature measurement location of cathode conductor are pyrometer fire-end, described housing is built-in with filling material, has two in the described housing with the upper conductor group.
Filling material in the described housing is a magnesium oxide powder.The material of described outer tube is a stainless steel.
Adopt such scheme, the armoured thermocouple with the many signal outputs of measuring point of the present utility model because two are encapsulated in the housing with the upper conductor group, has also just had the pyrometer fire-end more than two.Like this, can realize obtaining a plurality of signal outputs with measuring point.Make thermopair of the present utility model have easy to install, advantage such as volume is little, withstand voltage, antivibration simultaneously, and its length can reach more than the 50m, the multichannel output signal is isolated mutually, strong interference immunity.
Description of drawings
Fig. 1 is the structural representation of the utility model with the armoured thermocouple of the many signal outputs of measuring point;
Fig. 2 is that the A-A of Fig. 1 is to cut-open view.
Among the figure: 1-housing, 2-positive wire, 3-cathode conductor, 4-pyrometer fire-end, 5-filling material.
Embodiment
As shown in Figure 1 and Figure 2, armoured thermocouple with the many signal outputs of measuring point of the present utility model, it comprises housing 1, lead group in housing 1, described lead group comprise that positive wire 2 of a positive wire 2, cathode conductor 3, described lead group and cathode conductor 3 are pyrometer fire-end 4 near the junction of temperature measurement locations.Described housing 1 is built-in with filling material 5, and described filling material 5 generally is a magnesium oxide powder.The material of described housing 1 is a stainless steel.
The maximum characteristics of the utility model are to have two with the upper conductor group in the described housing 1.Present embodiment is to be example with four lead groups, promptly has four pyrometer fire-end, can obtain four temperature signals simultaneously.Certainly, the quantity of lead group can also be two, three, five or more according to actual needs.
