Flame monitoring in industrial burners with semiconductor-based UV sensors focusing on hydrogen-flame

Resumen
Using semiconductor based sensors for flame detection, such as presented with this article can be regarded as a fascinating approach not just with regards on costs and safety. Additionally, looking at environmental and sustainability aspects using semiconductor sensors instead of discharge tubes is a useful tool towards durability and longevity. The possibility of working with two different sensor chips for two different kind of irradiadion (UV and IR) in one small size sensor housing opens up a multitude of new and interesting application possibilities.

2024 – Measuring UV radiation without filters – silicon carbide (SiC) photodiodes make it possible

Abstract
For more than 20 years, the Berlin-based company sglux GmbH has been producing photodiodes and sensors for measuring UV radiation, as used in many areas of industrial production, medical technology, combustion control and for monitoring UV disinfection processes. The precise detection of the ultraviolet irradiance is of great importance for a controlled and efficient functioning. sglux solves these tasks with SiC-based photodiodes, since 2009 from in-house semiconductor production. SiC photodiodes have an advantage in the detection of UV radiation due to their high band gap of 3.26 eV, as they are insensitive to visible and near-infrared radiation. In addition, SiC photodiodes have very low dark currents, so that even the smallest amounts of radiation can be detected. In the measurement of strong UV radiation, SiC scores with its high resistance to degradation.

2024 Digital UV Sensors – The Smartphone becomes a Radiometer

11. junio 2024 von sglux

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.

2023 – Towards Sic-Based VUV Pin-Photodiodes – Investigations on 4H-SiC Photodiodes with Shallow Implanted Al Emitters

Towards SiC-Based VUV Pin-Photodiodes – Investigations on 4H-SiC Photodiodes with Shallow Implanted Al Emitters

Zusammenfassung
4H silicon carbide (SiC) based pin photodiodes with a sensitivity in the vacuum ultraviolet spectrum (VUV) demand newly developed emitter doping profiles. This work features the first ever reported 4H-SiC pin photodiodes with an implanted p-emitter and a noticeable sensitivity at a wavelength of 200 nm. As a first step, Aluminum doping profiles produced by low energy ion implantation in 4H-SiC were characterized by secondary-ion mass spectrometry (SIMS). Photodiodes using these shallow emitters are compared to one with a deep p-emitter doping profile employing IV characteristics and the spectral response. SIMS results demonstrate the possibility of shallow Alimplantation profiles using low implantation energies with all emitter profiles featuring characteristic I-V results. For some shallow doping profiles, a meassurable signal at the upper limit of the VUV spectrum could be demonstrated, paving the way towards 4H-SiC pin photodiodes with sensitivities for wavelengths below 200 nm.

Marker Substances in the Aroma of Truffles

Abstract
The aim of this study was to identify specific truffle marker substances within the truffle aroma. The aroma profile of different truffle species was analyzed using static headspace sampling with gas chromatography mass spectrometry analysis (SHS/GC-MS). Possible marker substances were identified, taking the additional literature into account. The selected marker substances were tested in an experiment with 19 truffle dogs. The hypothesis “If trained truffle dogs recognize the substances as supposed truffles in the context of an experiment, they can be regarded as specific” was made. As it would be nearly impossible to investigate every other possible emitter of the same compounds to determine their specificity, this hypothesis was a reasonable approximation. We were interested in the question of what it is the dogs actually search for on a chemical level and whether we can link their ability to find truffles to one or more specific marker substances. The results of the dog experiment are not as unambiguous as could have been expected based on the SHS/GC-MS measurements. Presumably, the truffle aroma is mainly characterized and perceived by dogs by dimethyl sulfide and dimethyl disulfide. However, as dogs are living beings and not analytical instruments, it seems unavoidable that one must live with some degree of uncertainty regarding these results.

2021 – TOCONs with reduced dead times used for the detection of fire and combustion burner flames

11. junio 2021 von sglux

Dr. Tilman Weiss, sglux GmbH, Berlin, Germany

TOCONs for the detection of fire and combustion burner flames

Abstract
The standard sglux TOCONs are featured by a relatively high time constant that extends from 30 ms (low sensitivity TOCONs) until 80 ms (high sensitivity TOCONs). Most of the TOCON applications benefit from this high time constant because usually the TOCON’s application is to measure a UV irradiation that slowly changes. Such applications are e.g. the control of UV disinfection and UV curing sources. Short changes of signal caused by electromagnetic or high frequency influences are averaged – which is a benefit. However, looking at flame detection in heaters or looking at fire detection applications this relatively high time constant may cause problems. The present report presents opportunities to reduce the dead time of the TOCONs.
