The use of infrared thermometer attention problems and industrial applications
Infrared temperature measurement technology in the production process, in product quality control and monitoring, equipment online troubleshooting and safety protection as well as energy saving and other aspects of infrared thermometers
Played an important role. In the past 20 years, non-contact infrared body thermometer in the rapid development of technology, performance continues to improve, functionality continues to enhance the variety continues to increase, the scope of application is also expanding. Than the contact temperature measurement method, infrared temperature measurement has a fast response time, non-contact, safe to use and long service life and other advantages. Non-contact infrared thermometer, including portable, online and scanning three series, and a variety of options and computer software, each series has a variety of models and specifications. In different specifications of the various models of thermometer, the correct choice of infrared thermometer model is very important to the user infrared thermometer should pay attention to when using what problems in order to measure the temperature, the instrument will be aligned to the object to be measured, press the trigger in the instrument's LCD to read out the temperature data, to ensure that the arrangement of the distance and the ratio of the size of the spot, and the field of view.
Infrared thermometer should pay attention to the use of the problem:
1, only the surface temperature measurement, infrared thermometer can not measure the internal temperature.
2, wavelengths above 5um can not be through the quartz glass for temperature measurement, glass has a very special reflection and transmission characteristics, does not allow accurate infrared temperature readings. But can be measured through the infrared window temperature. Infrared thermometer is good not for bright or polished metal surface temperature measurement (stainless steel, aluminum, etc.).
3, locate the hot spot, to find the hot spot, the instrument is aimed at the target, and then scanning up and down movement on the target, until the hot spot is determined.
4, pay attention to the environmental conditions: steam, dust, smoke and so on. It blocks the optical system of the instrument and affects the accurate temperature measurement.
5, the ambient temperature, if the pyrometer is suddenly exposed to ambient temperature difference of 20 ℃ or higher, allowing the instrument to be adjusted to the new ambient temperature within 20 minutes.
Infrared thermometer correctly select the choice of infrared thermometer can be divided into 3 aspects:
(1) Performance indicators, such as temperature range, spot size, operating wavelength, measurement accuracy, window, display and output, response time, protection accessories;
(2) Environmental and working conditions, such as ambient temperature, window, display and output, protection accessories;
(3) other selection aspects, such as ease of use, maintenance and calibration performance and price, also have a certain impact on the choice of pyrometer.
