Abstract
The utility model relates to a linear temperature measuring cable comprising a positive thermocouple wire, a negative thermocouple wire, and a grounding lead. The positive thermocouple wire and the negative thermocouple wire penetrate respectively through two first fiber mesh sleeves, and then penetrate through a second fiber mesh sleeve together with the grounding lead. The outer side of the second fiber mesh sleeve is, from inside to outside, provided with a shielding layer, an insulation layer, and a protection layer sequentially in an attached manner. NTC thermosensitive powder can be respectively disposed in the first fiber mesh sleeve and the second fiber mesh sleeve in a filled manner. The linear temperature measuring cable can be used for the real-time dynamic monitoring of the detected object in a relatively wide temperature range (0-200DEG C), and has advantages of high stability, high reliability, and high precision.
Description
Technical field
The utility model relates to a kind of linear cable for measuring temperature, relates in particular to a kind of linear cable for measuring temperature at 0～200 ℃ of energy thermometric.
Background technology
Linear dynamic surface thermocouple has the feature of real-time dynamic monitoring testee temperature, is able to extensive use.At present, this type of thermocouple is applicable to 80 ℃ of above high temperature ranges conventionally, cannot monitor the temperature range lower than 80 ℃.And often at the so-called low temperature environment below 80 ℃, just there is potential safety hazard in many regions or equipment surface.As power transmission cable of oil tank surface, oil pipeline, coal bunker, silo, freight house, dangerous goods store, tunnel, machine room, control cubicle, coal handling system transport tape and power plant, transformer station etc.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of and can to measured object, carry out in lower temperature range the linear cable for measuring temperature of real-time dynamic monitoring, just energy early warning when accident does not occur, make user have the sufficient time and take appropriate measures, Accident prevention occurs.
For solving the problems of the technologies described above; the technical scheme that the utility model adopts is: a kind of linear cable for measuring temperature; comprise positive thermocouple wire, negative thermocouple wire and earth lead; described positive thermocouple wire and negative thermocouple wire are through respectively in two the first fiber nets; and be through in the lump in the second fiber net with earth lead; the outside of described the second fiber net is by inner outward successively with screen, insulating barrier and protective layer, and described the first fiber net and the second fiber net be filling NTC thermo-sensitive material powder respectively.Note: NTC(Negative Temperature CoeffiCient) refer to temperature rising resistance and be thermistor phenomenon and the material that exponential relationship reduces, has negative temperature coefficient), be a kind of widely resistance material of application.
The utility model optimal technical scheme is: described two the first fiber nets wearing positive and negative two thermocouple wires in are respectively twisted pair construction.Described the first fiber net and the second fiber net are alkali-free glass fiber cloth net, and described screen is Aluminium Foil Package coating, and described insulating barrier is nonwoven fabrics coating layer, and described protective layer is teflin tape coating layer.
The beneficial effects of the utility model: 1, NTC thermo-sensitive material device belongs to negative temperature coefficient thermistor composition, can can reduce along with the rising resistance of temperature, thereby can make thermocouple export the millivolt signal of minimum resistance section, to reach the effect of maximum temperature output, can in wide temperature range (0-200 ℃), to testee, carry out real-time dynamic monitoring.2, positive and negative two thermocouple wires are twisted pair construction, and with earth lead and outer cladded aluminum foil screen, can reduce the impact of extraneous interference signal on thermocouple output signal, thereby reach the accuracy of measurement.3, outermost is two-layer is nonwoven fabrics and polytetrafluoroethylene coating layer, has dual waterproof, feature that again can be crooked arbitrarily.
This linear cable for measuring temperature can be wrapped in testee surface, and when the temperature of any point is elevated to alarm temperature point, system just can be reported to the police.In electric control chamber, also can monitor at any time the maximum temperature of all control points, the operating mode of understanding equipment or cable.There is the advantages such as high stability, high reliability, high accuracy.
Below in conjunction with drawings and Examples, technology contents of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the linear cable for measuring temperature of a kind of embodiment of the utility model.
Embodiment
As shown in Figure 1, the linear cable for measuring temperature of the present embodiment, comprises positive thermocouple wire 1.1, negative thermocouple wire 1.2, two the first fiber nets 2, the second fiber net 3 and earth leads 7.Positive and negative two thermocouple wires adopt the thermocouple wire of K type or other types, nickel chromium triangle material just very, negative pole is nisiloy material, thermocouple wire diameter is 0.4mm, and earth lead 7 materials are pure nickel wire, and diameter is 0.3mm, positive and negative two thermocouple wires are through respectively in two the first fiber nets 2, and become twisted pair construction moulding, earth lead 7 to be through in the middle of two the first fiber nets, be through in the lump in the second fiber net 3 with two the first fiber nets.The outside of the second fiber net 3 by inner outward successively with screen 4, insulating barrier 5 and protective layer 6.The first fiber net 2 and the second fiber net 3 adopt alkali-free glass fiber cloth net, and screen 4 adopts Aluminium Foil Package coating, and insulating barrier 5 adopts nonwoven fabrics coating layer, and protective layer 6 adopts teflin tape coating layer.The first fiber net 2 and the second fiber net 3 be filling NTC thermo-sensitive material powder respectively, by soaking into technique, by NTC thermo-sensitive material powder filling in the mesh of the first fiber net 2 and the second fiber net 3.
