One of the best-known natural sources of ultraviolet (UV) radiation is the sun, which emits sunlight and radiates heat to planet earth.
In addition to the sun, there are other unnatural sources of ultraviolet radiation emission, the best known being fluorescent lamps, which emit a low amount of UV radiation, in the industrial area, UV radiation is present in the most diverse sectors, food, automotive, health, and chemical are examples of industrial areas that use UV in their processes or products.
As a definition, ultraviolet radiation can be considered as all electromagnetic radiation with a wavelength between 100nm and 400nm, this wavelength range being due to three main types of UV rays: UVA with a wavelength range between 315nm and 400nm, UVB with a wavelength range between 280nm and 315nm and UCV with a wavelength range between 200nm and 280nm.
In addition to these three types, there is also the wavelength range from 100nm to 200nm, which is considered the UV vacuum range, where the wavelength is absorbed by the air and starts to propagate through nitrogen.
UVA: Rays with greater incidence on planet earth as they are not absorbed by the ozone layer.
UVB: Rays partially absorbed by the ozone layer.
UVC: The rays are 100% absorbed by the ozone layer and have a bactericidal sterilization factor due to their wavelength.
Due to its photochemical action, ultraviolet rays have several applications, the most common being beauty and skin care, detection of counterfeit coins, document verification, crime scene inspection, gem and mineral inspection, non-destructive testing, healing of paints and surfaces, and the sterilization or germicidal action.
Formation of UV light in lamps.
By energizing atoms, through heat, gamma radiation, X-ray or cosmic rays, electrons can absorb energy and jump into outer orbitals.
On the way back, ionization occurs, that is, the energy is returned as UV light, visible or invisible, depending on the energy leap of the electron and the type of lamp.
One of the ways to control the growth of microorganism colonies is through ultraviolet C (UVC) ray disinfection systems. This type of system, in general, has a source for germicidal action, which uses specific lamps, whose ray emission is capable of neutralizing microorganisms, whether they are arranged on surfaces, in suspension or passing through (controlled flow).
Due to the photochemical reaction, exposure to UVC rays causes changes in the genetic material of the microorganisms' cells, making them sterile, thus preventing their proliferation.
Sensor Technology has a team specialized in industrial sterilization projects via ultraviolet ray emitters. We offer the most modern disinfection solutions for the various industrial areas, ensuring process safety, the integrity of its employees, compliance with current regulations and compliance with the specifications required for the project.
How it works
With the identification of which colonies are present in the place to be sterilized, the dimensioning of the UV system can be determined in order to prevent the proliferation of these microorganisms. This impediment occurs due to ultraviolet rays directly affecting the cellular structures of each of the microorganisms, thus, this exposure to UV rays makes these organisms sterile, preventing their proliferation.
Through the controlled emission of UV rays it is possible to determine the effectiveness of the inactivation, reaching 99.9% of inactivation of the micro organisms when the colonies are known and with dimensioned projects.
Because they are developed on demand and according to each need, Sensor Technology's UV disinfection systems are effective in sterilizing surfaces, environments and products in general, making them recognized in the market for their excellent performance and excellent cost-effectiveness.
