1. Current output signal conversion calculation

Ultraviolet intensity range 0-15 mW/cm2, 4~20mA output, when the output signal is 12mA, calculate the current ultraviolet intensity value. The span of this ultraviolet intensity range is 15 mW/cm2, expressed by 16mA current signal, 15/16=0.9375, that is, the current 1mA represents the ultraviolet intensity change of 0.9375 mW/cm2, the measured value is 12mA-4mA=8mA, 8*0.9375=7.5 mW/cm2, and the current ultraviolet intensity is 7.5 mW/cm2.

2. Voltage output signal conversion calculation

Ultraviolet intensity range 0-15 mW/cm2, 0-10V output, when the output signal is 5V, calculate the current ultraviolet intensity value. The span of the UV intensity range is 0-15 mW/cm2, expressed by a 10V voltage signal, 15/10=1.5, that is, a voltage of 1V represents a change of 1.5 mW/cm2 in UV intensity, and the measured value is 5V-0V=5V, 5*1.5 =7.5 mW/cm2, and the current UV intensity is 7.5 mW/cm2.

UV sensor FAQs

What is ultraviolet light?

Ultraviolet light refers to the wavelength of 10nm-400nm in the electromagnetic spectrum, which cannot be detected by the naked eye. Ultraviolet rays are divided into three categories: UVA, UVB, and UVC according to the band:

1. UVA has strong penetrability of long-wave ultraviolet rays, with a wavelength of 315 nm-400 nm. It can destroy elastic fibers and collagen fibers and can make the skin tan.

2. UVB is a medium-wave ultraviolet that has an erythema effect and can promote mineral metabolism and the formation of vitamin D in the body. The wavelength is 280 nm-320 nm, but long-term exposure is not recommended because it will suntan the skin and cause erythema peeling.

3. UVC is a short-wave ultraviolet light that has a sterilizing effect. The wavelength is 200 nm-280 nm. The UVC band is very harmful to the human body. Short-term exposure can burn the skin. If it is exposed for a long time, it will cause skin cancer.

When used in a normal environment, our company provides a two-year warranty.
