What is an UV sensor?
UV sensors are used for measuring and controlling ultraviolet radiation. In a permanent setup, the sensor is mounted in a fixed position. It measures the UV radiation levels and transmits the data to a device. Depending on what kind of device receives the signal, you can programme a task, e.g. trigger an alarm or an action. You can also measure UV radiation using a handheld meter, which immediately converts the measured value into a readable value.
UVA, UVB, UVC or broadband sensor
We distinguish between UVA, UVB, UVC, etc. on account of their different wavelengths.
The UVA rays have a wavelength of between approx. 315 and 400 nm (long waves).
UVB rays have a wavelength of between 280 and 315 nm, and UVC rays have a wavelength of between 100 and 280 nm (short-wave radiation). If the radiation is between 10 and 100 nm, then it is not part of the UV spectrum; it belongs to what is known as soft X-ray radiation.
UVA, UVB, UVC or broadband sensor. If you want to measure across a wide spectrum, you can choose a broadband sensor that can measure all wavelengths.
Use of a UV sensor in the sector
The sensor can be used in various market sectors: in industry for curing paints and adhesives, as a method of disinfection in hospitals, in SMEs, for instance, in tanning studios where it is necessary to verify that the sunbeds are still working properly.
A UV sensor can be used wherever ultraviolet radiation is involved.
Which UV sensor do I need?
We will look at which sensor best suits your requirements according to the particular application and circumstances in question. For instance, a UV sensor that is being used to measure a continuous production process in which bacteria are to be killed, has a different set of properties to a sensor that needs to be immersed in a liquid.
UV sensors can feature 4…20mA, 0…5V or digital (USB / CAN) outputs. You can also opt for a UVA, UVB, UVC or broadband sensor.
If you need to record data, you can choose a UV data logger. Only when we have fully analysed the situation can we advise you properly about the right type of sensor and device you need to monitor the measured values.
