UV energy meter principle

The Linshang UV energy meter uses an intelligent single-chip acquisition scheme. The measurement principle is to first convert the weak current signal of the ultraviolet detector into a digital signal through an ADC analog-to-digital conversion chip. Then, the single-chip computer collects the digital signal and adjusts it through software. To UV power, UV energy is obtained by integrating UV power with time. In this process, one needs analog-to-digital conversion to get the UV power, and the other needs integration to get the energy value. If high accuracy is required, the acquisition time must be fast enough, generally at least 1000 times per second, so that the integrated energy value is more accurate.

For the intelligent single chip acquisition scheme, the power value is first measured, and then the energy value is calculated. In this way, the UV energy meter adopting this scheme displays real-time power value, maximum power value and energy value at the same time. It also integrates temperature measurement.

The principle and price of UV energy meter


Linshang UV energy meter LS128 adopts high-speed multi-point acquisition, which can simultaneously test power, energy, temperature and time. It can record all the data of the acquisition process, and get the curve data in the process. It is convenient to analyze the UV intensity distribution and temperature distribution of various points in the curing furnace, as well as process analysis and process parameter formulation during the production process.
