Dettaljat spjegazzjoni ta ' statiku karatteristika kalibrazzjoni ta' infrared termometru
1. Iddetermina it-temperatura kejl firxa
The temperature measurement range is the most important performance index of the thermometer. Each type of thermometer has its own specific temperature range. Therefore, the user's measured temperature range range must be considered accurately and comprehensively, la wisq narrow nor too wide. Skont għal il-liġi ta' blackbody radiation, the change of radiation energy caused by temperature in the short-wave band of the spectrum will exceed the change of radiation energy caused by emissivity error. Therefore, it is is better to use short-wave as much as possible when measuring temperature.
2. Sempliċi operazzjoni u konvenjenti użu
Infrared termometri should be intuwittiv, easy to operate, and easy for operators to use. Among them, portable infrared termometri are small, light, and portable temperature measurement instruments that integrate temperature measurement and display output. The temperature can be displayed on the display panel and different temperature information can be output, and some can be operated by remote control or computer software program. In the case of harsh and complicated environmental conditions, a system with a separate temperature measuring head and display can be selected for easy installation and configuration. The signal output form matching the current control equipment can be selected.
3. Performance indicators
Such as temperature range, spot size, operating wavelength, measurement accuracy, response time, etc.; environmental and working conditions, such as ambient temperature, window, display and output, protective accessories, etc.; other options, such as ease of use, maintenance and calibration performance, and Price, etc., also have a certain impact on the choice of thermometer. bi il kontinwu żvilupp ta ' teknoloġija u teknoloġija, infrared termometru disinn u ġodda żviluppi jipprovdu utenti bi diversi funzjonijiet u multi-skop strumenti, tespandi l-għażla .
4. Iddetermina l- ottika riżoluzzjoni (distanza u sensittività)
The optical resolution is determined by the ratio D to S, li is the ratio of the distance D between the pyrometer to the target and the diameter S of the measurement spot. If the thermometer must be installed far away from the target due to environmental conditions, and a small target must be be measured, a a small target must be measured, a termometru with high optical resolution should be selected. The higher the optical resolution, i.e. increasing il D:S ratio, the higher the cost of the pyrometer.
