2024 Digital UV Sensors – The Smartphone becomes a Radiometer

Dr. Tilman Weiss, sglux GmbH, Berlin, Germany

Abstract
Sensor Magazin 4/2024 (c) Magazin Verlag

UV radiation is used in many areas of industrial production, in medical devices and for disinfection. Precise measurement of irradiance is important for the controlled and efficient use of UV radiation. The UV measuring devices used for these applications must be able to measure the UV irradiance reliably, reproducibly and traceably over 13 orders of magnitude, from a few pW/cm2 up to 10 W/cm2. This is where digital measuring probes show their strengths.

Safester UVC FAQ

Can I also connect sensors, e.g. from the Radiometer SXL 55, to a Safester UVC hand-held device?

No. Only sensors with an appropriate calibration can be connected to the Safester UVC. The device would issue an error message.

Can I also use the Safester UVC for hazard assessment at other sources?

No, the sensors of the Safester UVC are only calibrated to Hg low-pressure sources. The use on other sources will lead to incorrect results. In certain cases it is possible to use the device to assess a potential hazard. We will be happy to explain to you when this is possible and what needs to be taken into account.

Radiomètres UV FAQ

How much does a good UV radiometer cost?

UV radiometers are available on the internet for as little as about €50. However, we do not recommend buying these radiometers, as they usually do not provide any information about the calibration procedure and the spectral properties of the sensor. For hobby UV measurements or for a rough estimate of the UV irradiance during laboratory experiments, we recommend the measuring devices from the American manufacturer Solarmeter. These devices are based on an sglux SiC photodiode, are robust and come with calibration and spectral information. They are offered in various web shops for around EUR 200. The sglux UV radiometers cost about EUR 1,000. They are used in industrial applications or for scientific work where precise knowledge of the irradiance is relevant. In contrast to the Solarmeter products, our radiometers offer additional functions, such as dose measurement and a logging function. The sglux radiometers also have a field of view which is almost perfectly matched to the cosine function. This allows for a good reproducibility of the measurements and a good comparison with measurements taken at other locations. Another advantage of purchasing a sglux measurement device is that that we customize our devices in cooperation with the customer with regard to the dynamic range, the spectral properties and the PTB-traceable calibration, which is always included in the price. This is how we ensure the measurement success of our customers. The measurement devices from sglux are a bit less expensive than other devices on the market that are suitable for professional use. The reason for this is the display unit chosen by sglux, a smartphone. This eliminates the costs of an elaborate in-house production of the display unit. Sometimes a UV radiometer is not enough. This is always the case when knowledge of the total value (integral) of a radiation source does not provide sufficient information, but rather the spectrum of the source, resolved by wavelength, is to be determined. For this, a spectroradiometer is required. In our laboratories, we use the BTS spectrometers from Gigahertz Optik for this purpose, and we can recommend their purchase.

Which waterproof UV measuring device can I operate permanently outdoors?

sglux offers the UV transmitter, a solar-powered network node with a connection to the mobile phone network or the UVMicrolog data logger. Both devices can be equipped with different sensors and different calibrations.

Which device is suitable for a belt application (sterilization or curing line)?

sglux is specialized in in-line monitoring, i.e. the continuous monitoring of emitters using permanently installed sensors. By using the radiation-hard semiconductor material SiC, this is also possible at very high irradiation. If the design of the system does not permit in-line monitoring, the uvLink or the UVMicrolog can move across the conveyor belt.

Which devices are suitable for DVGW/ÖNORM-compliant measurement?

sglux offers the UVRRM reference radiometer, which is approved for many years. If more than one or special calibrations are required (e.g. LED), the UV Radiometer SXL 55 or the UVTOUCH should be used.
