Abstract
The utility model discloses a temperature sensor for mine. The temperature sensor for mine comprises an intrinsically safe shell, inside which a temperature sensor circuit board assembly is installed. A temperature sensor probe connected with the temperature sensor circuit board assembly extends out from the intrinsically safe shell. The intrinsically safe shell is also provided with a cable connector connected with the temperature sensor circuit board assembly. The temperature sensor for mine is safer, has a dustproof function, and is applicable in a complicated mine environment.
Description
Technical field
The utility model relates to a kind of temperature sensor, relates in particular to a kind of mining temperature sensor.
Background technology
Temperature sensor is that a kind of temperature variant rule of the various physical propertys of material of utilizing is the sensor of temperature transition for electric weight.Temperature sensor is of a great variety in the market, can be divided into contact and contactless two large classes by metering system, is divided into thermal resistance and thermopair two classes according to sensor material and electron component characteristic.Yet the structural design of at present common temperature sensor is difficult to adapt to complex environment under the mine.
The utility model content
The purpose of this utility model is to provide a kind of mining temperature sensor that is applicable to complex environment under the mine.
For achieving the above object, the utility model provides a kind of mining temperature sensor, comprise an intrinsic safety type shell, in the described intrinsic safety type shell temperature sensor scheme board component is installed, the temperature sensor probe that links to each other with described temperature sensor scheme board component stretches out outside the described intrinsic safety type shell, and described intrinsic safety type shell also is provided with the cable splice that links to each other with described temperature sensor scheme board component.
In the mining temperature sensor of the present utility model, circuit board is provided with the intrinsic safety type shell outward, and temperature sensor probe stretches out the intrinsic safety type shell, thereby so that mining temperature sensor safety and have dust reduction capability more be suitable under mine, using in the complex environment.
Description of drawings
Fig. 1 is the front view of mining temperature sensor of the present utility model;
Fig. 2 is the vertical view cutaway drawing of mining temperature sensor of the present utility model;
Fig. 3 is the circuit theory diagrams of mining temperature sensor of the present utility model.
Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing to mining temperature sensor of the present utility model:
With reference to illustrated in figures 1 and 2, the mining temperature sensor of present embodiment, comprise an intrinsic safety type shell 1, temperature sensor scheme board component 2 is installed in the intrinsic safety type shell 1, the temperature sensor probe 3 that links to each other with temperature sensor scheme board component 2 stretches out outside the intrinsic safety type shell 1, intrinsic safety type shell 1 also is provided with the cable splice 4 that is tightly connected with temperature sensor scheme board component 2, is tightly connected between this cable splice 4 and the intrinsic safety type shell 1.For portable, intrinsic safety type shell 1 top is provided with handle 5.
In conjunction with shown in Figure 3, temperature sensor scheme board component 2 is provided with: sample circuit, 8 toggle switchs, single-chip microcomputer, amplifying circuit and power modules, and wherein, sample circuit is used for the temperature data that temperature sensor probe 3 collects is taken a sample; Toggle switch is used for setting alarm temperature; Single-chip microcomputer is used for obtaining the temperature data that sample circuit obtains, convert thereof into corresponding temperature frequency signal and be sent to the main control system processing, the temperature data that simultaneously it is obtained and the temperature threshold that sets in advance compare, and if exceeded temperature threshold output alarm signal to main control system; Amplifying circuit exports main control system to after the temperature frequency signal of single-chip microcomputer output and output alarm signal are amplified.Power module is used for to power devices.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineering technical personnel in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
