Setting thermometer alarm thresholds and common temperature read false alarms
Can the alarm threshold of the thermometer be set, and what is the trigger result?
The alarm reminder of the temperature measurement system needs to set an alarm threshold. The size of this trigger value can be set. After triggering, the sound prompt built into the software can be called, or the sound can be recorded on site as a prompt; it can also be set on the operation terminal. Display the pictures of people suspected of having fever captured in the alarm state, and save them in the corresponding file directory for later verification; the specific operations are as described in the software settings.
Common problems caused by false alarms in temperature measurement.
In actual use of the temperature measurement system, because the temperature measurement system has not set up a reasonable temperature measurement area, it may be affected by the environment such as: direct air blowing, direct sunlight, mirror reflection, etc., which may cause the temperature to jump and alarm; or during area detection , there are people holding cigarette butts, hot water cups, other heating objects, heat collecting objects, etc. in the background, which may cause alarms; in actual use, if false alarms occur, be sure to pay attention to troubleshooting such problems.
Industrial infrared thermometer determines temperature measurement range
Determine the temperature measurement range: The temperature measurement range is the most important performance indicator of the thermometer. For example, infrared era products cover a range of -40℃-+3000℃, but this cannot be accomplished by one type of infrared thermometer. Each model of thermometer has its own specific temperature measurement range. Therefore, the user's measured temperature range must be considered accurately and comprehensively, neither too narrow nor too wide. According to the blackbody radiation law, the change in radiant energy caused by temperature in the short-wavelength band of the spectrum will exceed the change in radiated energy caused by the emissivity error. Therefore, shortwave should be used as much as possible when measuring temperature. Generally speaking, the narrower the temperature measurement range, the higher the resolution of the output signal for monitoring temperature, and the accuracy and reliability are easier to solve. If the temperature measurement range is too wide, the temperature measurement accuracy will be reduced. For example, if the target temperature being measured is 1000 degrees Celsius, first determine whether it is online or portable, and if it is portable. There are many models that meet this temperature.
