Determine the measurement distance of infrared temperature instrument；
When two light beams do not accumulate luminous point in measurand, readjust infrared temperature instrument and measurand away from
From.
Due to accumulating a luminous point in measurand of two light beams in angle setting before measurement window, therefore, it is possible to true
The measurement distance of fixed outer thermo detector, that is, determine correct measurement distance, and luminous point collects in measurand and ensures that measurement
To the correct region of measurand, the accuracy of thermometric is ensured that.
Because different measurands has different attributes, so that the optimal thermometric distance of measurand is not
Together, in order to adapt to this case, then, when thermometric is carried out to measurand using above-mentioned temp measuring method, the angle of two light beams
It is adjustable.By the angle for adjusting this two light beam, to adjust luminous point and the measurement window that two light beams are accumulated in measurand
Distance, and then adjust infrared temperature instrument measurement distance, to determine optimal thermometric distance according to different measurands, with true
Protect the accuracy of thermometric.For the ease of adjusting the angle of this two light beam, so, measurement window of two light beams respectively at infrared temperature instrument
The both sides irradiation measurand of mouth.
In order to implement above-mentioned temp measuring method, therefore, such a infrared temperature instrument need to be designed, it includes measurement window and two
Light source, the light beam of light source described in two can be in the measurand that angle is irradiated before the measurement window.
Fig. 1 is the schematic diagram of the infrared temperature instrument that the embodiment of the present invention is provided；Fig. 5 is that the embodiment of the present invention is provided
The sectional structure chart of infrared temperature instrument, refer to Fig. 1 and Fig. 5, and this example mid-infrared thermo detector includes measurement window 1, the and of housing 3
Two light sources, in the present embodiment this two light source is light emitting diode 2.As shown in figure 5, measurement window 1 is arranged on housing 3, two
