Abstract
The utility model discloses an absorption type digital temperature sensor which comprises a piece of ring-shaped magnet, a heat conduction resin layer embedded at the inner side of one end of the magnet, a digital temperature probe attached at the side of the heat conduction resin layer close to the interior of the magnet, a lead connected on the digital temperature probe, a shell leaning against the other end of the magnet, and a sealed insulating rubber block fully filled in the shell and the internal space of the magnet. The absorption type digital temperature sensor has the advantages that the digital temperature sensor is low in cost, good in performance and simple in use; the results are more accurate and stable during long-distance temperature data acquisition; and the absorption type digital temperature sensor can be used for independently acquiring the temperature of a point or for a distributed temperature acquisition system so as to acquire the ambient temperature of an area.
Description
Technical field
The utility model belongs to temperature automatic acquisition technology field, the especially application of digital temperature sensor material.
Background technology
At present, at industrial control field, comprise field of telecommunications, temperature sensor is widely used in the device temperature monitoring.Existing temperature sensor generally has installs inconvenient defective, needs perforate location or bolt location etc.Though the on-the-spot installation of common absorption type temp probe is simple and easy, mostly is occasionally thermal resistance type of thermoelectricity, when remote the application, the stability of image data and accuracy are difficult to be guaranteed.Especially for field of telecommunications, the telecommunication apparatus kind is various, working environment is complicated, device distribution is disperseed, and existing temperature sensor is difficult to adapt to the demand of field of telecommunications.
The utility model content
Technical problem to be solved in the utility model be existing temperature sensor when using at a distance image data unstable reliable, and on-the-spot loaded down with trivial details shortcoming is installed.
The technological means that the utility model adopted is: a kind of absorption type digital temperature sensor, it comprise a ring-type magnet, be embedded heat-conducting resin layer in an end inboard of this magnet, be attached to the inner side of close magnet of heat-conducting resin layer the digital temperature probe, be connected lead on the described digital temperature probe, be resisted against the other end of described magnet shell, fill the sealed insulation blob of viscose of full described shell and magnet inner space.
This absorption type digital temperature sensor has the following advantages: cost is low, performance good, use is simple and easy; When the remote capture temperature data, the result is more accurate and stable; Both can gather certain any temperature separately, also can be used for a distributed temperature acquisition system, gather the environment temperature in a certain zone.
Description of drawings
Fig. 1 is a kind of absorption type digital temperature sensor that the utility model proposes;
Fig. 2 is the temperature acquisition system that has adopted the absorption type digital temperature sensor among Fig. 1.
Embodiment
Referring to absorption type digital temperature sensor 10 shown in Figure 1, it comprises the magnet 3 of a ring-type, be embedded heat-conducting resin layer 2 in an end inboard of this magnet 3, be attached to the digital temperature probe 1 of close magnet 3 inner sides of heat-conducting resin layer 2, be connected the lead 5 on the described digital temperature probe 1, be resisted against the shell 6 of the other end of described magnet 3, fill the sealed insulation blob of viscose 6 of full described shell 6 and magnet 3 inner spaces, described digital temperature probe 1 is sealed in the magnet 1.
Described magnet 3 is strong magnets, and is cylindrical; Described heat-conducting resin layer 2 is a heat-conducting type epoxy resin; Described lead 5 is a shielded conductor, and is connected with the respective pin of digital temperature probe 1.
These absorption type digital temperature sensor 10 as a whole devices, applicable to the industrial occasions of all temps variation range at-55 ℃ to+125 ℃, 0.2 grade of measuring accuracy, transmission range can reach 500 meters.
When reality was used, strong magnets was adsorbed in the surface of testee with sensor, and installing/dismounting is very simple and easy.Because the heat-conducting type epoxy resin with digital temperature probe 1 is fitted has good conductive performance to temperature, can guarantee the accuracy of sampled data.Digital temperature probe 1 is converted into digital signal with the temperature data of sampling, and sends data to data acquisition unit by shielded conductor.Therefore, the analog acquisition mode that the sensor that the utility model proposes is more traditional, particularly when the remote capture temperature data, the result is more accurate and stable.In addition, described heat-conducting resin layer 2 and insulation blob of viscose 6 make whole sensor be in sealing state, then this sensor also have discharge water, etch-proof characteristics.This absorption type digital temperature sensor, cost is low, performance good, use is simple and easy, both can gather certain any temperature separately, also can be used for a distributed temperature acquisition system, gathers the environment temperature in a certain zone.
The distributed temperature acquisition system that is shown in Figure 2 can be applicable to the temperature survey of telecommunication apparatus.Absorption type digital temperature sensor 10 can be attached to the surface of telecommunication apparatus such as accumulator, traditional oils machine, the temperature data that is dispersed in diverse location, distinct device can be sent to data acquisition unit, and gives the monitoring host computer of upper end.Adopt the absorption type digital temperature sensor, easy installation and removal, wiring distance is far away, and data are accurately stable, and the mode of temperature acquisition is simple and reliable flexibly.For the distributed temperature acquisition system, only need that temperature sensor is adsorbed in the testee surface and get final product, a data collector can be gathered the temperature of multichannel equipment, can save monitoring cost greatly.
Though the utility model with preferred embodiment openly as above; but it is not to be used for limiting claim; any those skilled in the art are not in breaking away from spirit and scope of the present utility model; can make possible change and modification, therefore protection domain of the present utility model should be as the criterion with the scope that the utility model claim is defined.
