Abstract
The utility model discloses a new type sensor, relates to the technical field of sensors, and specifically relates to improvement techniques of thermocouple sensors. The new type sensor comprises a thermocouple sensor composed of a wire connection box, a protective tube, an insulation tube and a thermode. The wire connection box is connected to the left end of the protective tube. The thermode is arranged in the protective tube. The thermode is sleeved with the insulation tube. The thermode has a step-like structure in which the right portion diameter is less than the left portion diameter. The left end of the protective tube is provided with a screwed nipple. The right end of the protective tube has a hemispherical structure. The right portion of the protective tube is provided with a groove at a position near the hemispherical portion. The groove is formed in the surface of the protective tube in an annular manner in the circumferential direction. A carbon fiber enhanced epoxy resin composite material layer is arranged outside the groove. The outer cylinder surface of the carbon fiber enhanced epoxy resincomposite material layer is protruded from the surface of the small-diameter portion of the right portion of the protective tube. When an existing thermocouple sensor is used, the parallel connection end of the protective tube is easy to deform due to the collision of an external force to influence the normal utilization of the sensor; and the new type sensor of the utility model can be used to the problem.
Description
Technical field
The utility model relates to sensor technical field, is specifically related to the improvement technology of thermocouple sensor.
Background technology
Sensor is a kind of pick-up unit, can experience measured information, and can, by the information of experiencing, be for conversion into according to certain rules the information output of electric signal or other desired forms, to meet the requirements such as transmission, processing, storage, demonstration, record and control of information.It is to realize the primary link that automatically detects and automatically control.Sensor is in utilizing the process of information, and what first will solve will obtain information accurately and reliably exactly, and sensor is main path and the means of obtaining information in nature and production field.Sensor technology, in the vital role of developing the economy, promoting aspect social progress, is fairly obvious.The development in this field is all attached great importance in countries in the world.Believe in the near future, sensor technology will there will be a leap, reach the new height matching with its critical role.Sensor kind has: resistance sensor, variable-frequency power sensor, LOAD CELLS, resistance strain type sensor, piezoresistive transducer, thermal resistance sensor etc.The basic perceptional function of sensor can be divided into the ten large classes such as thermal sensing element, light activated element, gas sensor, force sensing element, magneto sensor, humidity-sensitive element, acoustic sensor, radioactive ray sensitive element, color sensor and taste photosensitive elements.
Thermocouple sensor is a kind of sensor of measuring temperature, terminal box, protection tube, thermode, insulation tube, consists of.This kind of sensor temperature measuring head is the rectangular or circular structure of stretching out, and during use, the protection tube end of thermometric is easily subject to external force collision and is out of shape, and affects the normal use of sensor.
Summary of the invention
The utility model provides a kind of novel sensor, and when the utility model has solved existing thermocouple sensor use, protection tube end is easily subject to external force collision and is out of shape, and affects the problem of the normal use of sensor.
For addressing the above problem, the utility model adopts following technical scheme: a kind of novel sensor, comprise the thermocouple sensor that terminal box 1, protection tube 2, insulation tube 3 and thermode 4 form, terminal box 1 connects protection tube 2 left ends, in protection tube 2, be provided with thermode 4, thermode 4 outsides are set with insulation tube 3; Thermode 4 is ladder-type structures that right part diameter is less than left part diameter; Protection tube 2 left ends have threaded connector 7, and protection tube 2 right-hand members are hemisphere face structures; In protection tube 2 right part next-door neighbour hemisphere face positions, be provided with groove 6; groove 6 along the circumferential direction arranges ringwise on protection tube 2 surfaces; in groove 6 outsides, be provided with carbon-fibre reinforced epoxy resin composite material layer 5, carbon-fibre reinforced epoxy resin composite material layer 5 outer cylinder surface protrude from the surface at protection tube 2 right part minor diameter positions.
In use, the right-hand member parts of protection tube right part minor diameter are arranged in thermometric environment, are easily subject to heated product and clash into; owing to adopting carbon-fibre reinforced epoxy resin composite material layer; improved the shock proof performance of sensor, sensor bulk strength improves, and extend serviceable life.

Embodiment
With best embodiment, the utility model is described in detail below
.
As shown in Figure 1-2, a kind of novel sensor, comprises the thermocouple sensor that terminal box 1, protection tube 2, insulation tube 3 and thermode 4 form, and terminal box 1 connects protection tube 2 left ends, is provided with thermode 4 in protection tube 2, and thermode 4 outsides are set with insulation tube 3; Thermode 4 is ladder-type structures that right part diameter is less than left part diameter; Protection tube 2 left ends have threaded connector 7, and protection tube 2 right-hand members are hemisphere face structures; In protection tube 2 right part next-door neighbour hemisphere face positions, be provided with groove 6; groove 6 along the circumferential direction arranges ringwise on protection tube 2 surfaces; in groove 6 outsides, be provided with carbon-fibre reinforced epoxy resin composite material layer 5, carbon-fibre reinforced epoxy resin composite material layer 5 outer cylinder surface protrude from the surface at protection tube 2 right part minor diameter positions.
Carbon-fibre reinforced epoxy resin composite material, its specific strength, specific modulus overall target are the highest in existing structure material.The field that has strict demand in density, rigidity, weight, fatigue properties etc., is requiring high temperature, occasion that chemical stability is high, and carbon fibre composite all has much advantage.
Finally it should be noted that: obviously, above-described embodiment is only for the utility model example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being amplified out thus or change are still among protection domain of the present utility model.
