Infrared temperature measuring device with auxiliary positioning function

The invention relates to an infrared temperature measuring device, in particular to an infrared temperature measuring device with an auxiliary positioning function.

Objects with temperatures above absolute zero will radiate infrared energy continuously due to the movement of their own molecules. The more active the movement of molecules, the more infrared energy is radiated. The infrared temperature measuring device collects the infrared energy radiated by the object. And converting the infrared energy into an electronic measurement signal, and the electronic measurement signal is calculated and processed to obtain temperature data of the object to be tested. The biggest advantage of the infrared temperature measuring device is that it is measured in a non-contact manner, which is quite practical and convenient for measuring the temperature of the object to be tested that is hot or difficult to reach.

Referring to FIG. 1 , a conventional infrared temperature measuring device includes an optical lens 11 , an infrared thermometer 12 , and an optical fiber 13 connecting the optical lens 11 and the infrared thermometer 12 , wherein the infrared thermometer 12 includes a The signal processing unit 121 and a display unit 122. During the measurement, the infrared light radiated by the object to be tested 10 is detected by the optical lens 11 , and the infrared energy signal is transmitted to the infrared thermometer 12 through the optical fiber 13 , and then the signal processing unit 121 The infrared energy signal is subjected to conversion processing, and the calculation result is displayed by the display unit 122 after the temperature value is calculated.

However, temperature measurement is performed using a conventional infrared temperature measuring device At the same time, a built-in laser beam is mainly projected onto the surface of the object to be tested 10 through the optical lens 11, but the laser beam interferes with the measurement result when measuring, so the temperature can only be measured. The laser beam is previously used to indicate the position to be measured, and the laser beam must be turned off when the temperature measurement is actually performed.

Moreover, the conventional infrared temperature measuring device cannot be applied to the measurement of the non-fixed position, that is, if the temperature of other positions is to be measured during the measurement, the measurement must be stopped first, and the measurement is to be started. The built-in laser beam confirms the new measurement position before the temperature measurement can be performed. And the conventional infrared temperature measuring device uses a laser light source capable of emitting a red laser beam. For measuring a high temperature red hot object to be tested, the spot light generated by the red laser beam is compared with the object to be tested. Not obvious enough, so even the surface projected onto the object to be tested cannot clearly identify the position of the temperature measurement.

Accordingly, it is an object of the present invention to provide an infrared temperature measuring device that can accurately position a temperature measuring position.

Therefore, the infrared temperature measuring device with the auxiliary positioning function of the present invention comprises a measuring device and an infrared thermometer connected to the measuring device.

Each of the pointing units 33 emits a light spot parallel to the optical axis of the sensing unit 32. Used to assist in indicating the sensing The measurement position of unit 32. The pointing units 33 can be turned on or off according to the needs of the user, and can also be turned off during non-measurement to avoid accidents.

Preferably, the sensing unit 32 and the pointing unit 33 are detachably disposed on the body 31, so that the user can change the suitable sensing unit 32 at any time according to the space and the environment. These pointing units 33.

It should be noted that the number of the pointing units 33 may be two or more. When attaching, the pointing units 33 need only be parallel to the optical axis of the sensing unit 32 and have the same pitch. In the preferred embodiment, each of the pointing units 33 is a laser light source that emits a laser beam, and the laser beam does not limit color, such as to improve the light spot generated by the laser beam and the object to be tested. The contrast is convenient for identification. The laser beam can be selected from blue, green, red, etc., but it is worth noting that if the pointing unit 33 is a laser source that emits a red laser beam, the power is not selected. Red laser beam of less than 5 mW, otherwise the contrast between the spot generated by the red laser beam and the object under red heat is not obvious enough, which affects the alignment accuracy during measurement. The result of the measurement produces an error.

The measuring device 3 is mounted on the auxiliary rod 4, and the length or angle of the auxiliary rod 4 can be adjusted. When measuring an object to be tested in a special space or environment, the auxiliary rod 4 can be adjusted. The length or angle, and thus the relative position of the measuring device 3 and the object to be tested, can be measured. For example, when measuring a high radiant heat object, the auxiliary rod 4 can be used The use allows the user to measure away from the high radiant heat source, improving operability and safety. On the other hand, the relative position of the measuring device 3 and the object to be tested 2 can also be shortened by using the auxiliary lever 4, the error during measurement is effectively reduced, and the measured temperature data is more accurate.
