Abstract
The utility model discloses the contact photoelectric temperature probe with calibration function, comprise photoelectric commutator, sight glass lens, flange assembly, alundum tube, set up the light hurdle switching button correcting light hurdle value, and then when becoming actual non-contact temperature measuring in alundum tube fracture, just non-contact temperature measuring code can be realized through pressing light hurdle switching button, this function ensures that the accuracy error of thermometric is less than 5 ‰ FS, ensure that continuity and the accuracy of thermometric.
Description
Technical field
The utility model relates to contact photoelectric temperature probe, specifically, is the contact photoelectric temperature probe with calibration function.
Background technology
In commercial production, when high temperature production, measuring tempeature is a problem, and platinum rhodium thermocouple holds damage in high temperature moisture, because platinum rhodium is precious metal, not only increases measurement cost, also consumes national precious metal material.General user adopts radiant type thermometry, and this provides possibility to the use of photoelectric sensor technology.
Existing technology contact photoelectric sensor in use has following defect: alundum tube in use sends out into fracture, once alundum tube fracture, the situation of actual thermometric suddenly can not reduce 50-100 DEG C not etc., and this has had a strong impact on actual temperature measurement accuracy.Actual thermometric has departed from contact temperature-measuring category, becomes non-contact temperature measuring, and existing technology is that the secondary instrument of temperature measuring device is adjusted.Do like this is that other online temperature measuring devices according to neighbouring do reference; Or adopt estimated value to adjust secondary instrument as thermometric value.This does not all have scientific basis.
Utility model content
The purpose of this utility model provides a kind of contact photoelectric temperature probe with calibration function for the deficiency of existing contact radiation photoelectric sensor and defect, and then the continuous temperature measurement making temperature measurement on-line can provide accurate, stable.
For achieving the above object, the utility model provides following technical scheme:
The utility model relates to the contact photoelectric temperature probe with calibration function, comprise photoelectric commutator, sight glass lens, flange assembly, alundum tube, it is characterized in that, also comprise the light hurdle switching button correcting light hurdle value, described smooth hurdle switching button is arranged on photoelectric commutator, and described opto-electronic conversion button interior is provided with concrete body of heater parameter and obtains corresponding actual light hurdle value through standard stove calibration.
Compared with prior art, good effect of the present utility model is:
1. the utility model technology adopts the concrete body of heater parameter that provides of user to obtain corresponding actual light hurdle value through standard stove calibration to make light hurdle switching button, and then when becoming actual non-contact temperature measuring in alundum tube fracture, just can realize non-contact temperature measuring code through pressing light hurdle switching button, this function ensures that the accuracy error of thermometric is less than 5 ‰ FS.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the contact photoelectric temperature probe with calibration function;
Mark in accompanying drawing 1 is respectively: 1. photoelectric commutator; 2. sight glass lens; 3. flange assembly; 4. smooth hurdle switching button; 5. alundum tube.
Embodiment
The technological means realized to make the utility model, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, there is the contact photoelectric temperature probe of calibration function, comprise photoelectric commutator 1, sight glass lens 2, flange assembly 3, alundum tube 5, it is characterized in that, also comprise the light hurdle switching button 4 correcting light hurdle value, described smooth hurdle switching button 4 is arranged on photoelectric commutator, and described opto-electronic conversion button 4 inside is provided with concrete body of heater parameter and obtains corresponding actual light hurdle value through standard stove calibration.
Once alundum tube 7 ruptures, press light hurdle switching button 2 and can complete the conversion of contact to contactless temperature-measuring, still ensure the accuracy of thermometric, ensure that body of heater is produced and normally carry out.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, therefore all changes be intended in the implication of the equivalency by dropping on claim and scope are included in the utility model, any Reference numeral in claim should be considered as the claim involved by limiting.
