Abstract
The utility model relates to a granary optical fibre temperature-measuring cable, and the inner of a cable core is provided with an optical signal transmission unit, an electric transmission conducting wire and temperature measurement element. The cross-section of an outer sheath is in the ellipses shape, and both sides of the long axis direction of the ellipses are respectively provided with a reinforcement component. The temperature measurement cable has fast temperature measurement speed, convenient microcomputer monitoring, favorable use stability, low heat shield effect, and small temperature measurement data error.
Description
Affiliated technical field
The utility model belongs to a kind of optical cable, especially the optical cable used of barn temperature measuring.
Background technology
Existing barn temperature measuring generally adopts with the cable for measuring temperature of sensor as transmission medium, this cable and microcomputer connecting circuit complexity, and the Installation and Debugging trouble, measuring speed is slow during use, sensitivity is low, error is bigger.
Summary of the invention
In order to overcome the deficiency of existing barn temperature measuring cable, the utility model provides a kind of novel granary optical fiber temperature-measurement cable, and it has, and measuring speed is fast, error is little, be convenient to advantage such as micro computer monitoring.
Novel granary optical fiber temperature-measurement cable wrap provided by the utility model is drawn together cable core (4) and inner sheath (2) thereof, oversheath (1), optical signal transmission unit (6), transmission pressure (8), temperature element (5) that optical fiber and sleeve pipe thereof constitute are set in the cable core (4), reinforcement (3) is set in the oversheath (1).
In order to reduce cross-sectional area of the present utility model, during use stressed rationally, reduce the thermoshield effect, oversheath of the present utility model (1) can be made ellipse, in the both sides of long axis of ellipse direction one reinforcements (3) is set respectively.
The beneficial effects of the utility model be grain temperature measurement speed fast, be convenient to micro computer monitoring, good stability, thermoshield effect reduce during use, the temperature measurement data error is little.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
Transmission pressure in the drawings, 1, oversheath, 2, inner sheath, 3, reinforcement, 4, cable core, 5, temperature element, 6, the optical signal transmission unit, 7, packing material, 8.
Embodiment
Optical signal transmission unit (6), transmission pressure (8) and the packing material (7) that the temperature element (5) that cable core (4) is interior, optical fiber and sleeve pipe thereof constitute gone ahead of the rest stranded and coated inner sheath (2) with polythene material, again two wire rope as reinforcement (3) are set in parallel in the outer both sides of cable core and coat oval oversheath (1), just made the utility model with polythene material.
Claims (2)
1, a kind of novel granary optical fiber temperature-measurement cable comprises cable core and inner sheath thereof, oversheath, it is characterized in that being provided with in the cable core optical signal transmission unit, transmission pressure, temperature element that optical fiber and sleeve pipe thereof constitute, and reinforcement is set in the oversheath.
2,, it is characterized in that the oversheath xsect for oval, respectively is provided with a reinforcements in the both sides of long axis of ellipse direction by the described novel granary optical fiber temperature-measurement of claim 1 cable.
