The thermal imager uses a set of three parameter ranges
The thermal imager is a precision instrument for observation. Before using it, we need to design all the parameters of the equipment within the specified parameter range. Specifically, the parameters of that machine, let's discuss together below!
1. Determine the optical resolution of the device:
The optical resolution of the thermal imager is an important parameter when it is working. Researchers can obtain different imaging effects by setting different parameter ranges. Usually when we observe some relatively small objects, we will increase the resolution of the equipment to facilitate the observation of observers. The final value of this parameter is determined by the ratio of D and S, where D refers to the distance between the device and the target, and S refers to the measurement spot diameter S. So we only need to adjust these two values when adjusting the resolution range of the device. If the thermometer must be installed far away from the target due to environmental conditions, and a small target needs to be measured, a thermal imager with high optical resolution should be selected. The higher the resolution of the device, the higher the power consumption of the instrument.
2. Determine the temperature range of the equipment:
Another important parameter of a thermal imager is its temperature measurement range. We all know that it is an instrument designed to study objects through temperature measurement, so the temperature measurement range of the device is also very important. Each model has its own specific temperature range. Therefore, the user's measured temperature range must be considered accurate, neither too narrow nor too wide. Researchers can have a general understanding of the temperature of the object to be measured before measuring the temperature, and then set the temperature range of the instrument according to the temperature range of the object.
3. Response time of equipment method:
The response time of an instrument refers to the speed at which the device responds to changes in the temperature of an object. The response speed is mainly related to the photodetector and signal processing circuit of the instrument. Therefore, if you want to further guarantee the response speed of the instrument, you can adjust the parameters of these devices. The response speed of this device on the market is very fast. This is much faster than traditional contact temperature measurement methods. According to the different response speeds, thermal imagers are divided into two types: fast response and slow response. Usually we need to use high-speed equipment to observe some fast-moving objects, while some stationary objects only need to use slow-speed equipment models. Depending on the object state specifically studied, different device models are used.
