Theta Consult certifies the Information Security Management System (ISMS) according to the ISO 27001 standard

Hooray, we already have a SUSI Certificate! From 2019 Theta Consult Ltd. is working on the priority goal Development, implementation and Certification of Information Security Management System (ISMS), but for various reasons, this still did not happen.

From the beginning of 2020, at the insistence of the top management, more decisive steps were taken and with the help of a consulting company and the mobilization of its own staff, things worked out.

The new system includes both the general characteristics (processes) of a Management System (MS) and very specific requirements (controls) for Information Security (IS), and thus the whole ISMS system is formed.

A team of three specialists (Responsible for the three systems: ISMS, OHSAS and QMS) works under pressure (due to the short deadlines), but responsibly and selflessly. So, the collective mind and efforts gave the desired result!

At the end of March, a certification organization conducted an audit (remote) and Theta Consult received a good assessment of what was done, and in early May received the desired Certificate of Conformity of SUSI with the requirements of BDS EN ISO / IEC 27001: 2017 .

Congratulations on your success! Congratulations to the company and staff!

FeverBlock – fast and safe measurement of body temperature of large flows of people

09.02.2021Theta Consult

Theta Consult presented on the Bulgarian market a new product for monitoring body temperature of large flows of people of the leading manufacturer of security systems NUCTECH. The FeverBlock system combines an infrared thermal imaging camera and powerful self-learning algorithms to provide fast and accurate, non-contact temperature measurement to multiple people and to alert in real time when a person passes a temperature higher than normal. The system captures infrared radiation from people’s faces, and the calculation algorithms are adapted so that the measurement is not disturbed by accessories such as face masks or glasses, as well as by objects with a higher temperature, such as hot drinks cups, rechargeable batteries and others. FeverBlock self-calibrates to ambient temperature, thus reducing the measurement error to ± 0.3 ° C. In addition, the system takes into account the changing distance to the measurement object, which minimizes the typical deviations in temperature measurements of moving objects with standard infrared cameras.

FeverBlock is designed to operate successfully in places with large flows of people, such as airports, ports, public transport stops, hotels, hospitals, factories and industrial enterprises, malls and supermarkets. Thanks to its ability to measure the temperature of several people at once on the go, the system manages to monitor 120 people per minute without creating a risk of infecting control personnel. FeverBlock has its own computer with specialized software and a database in which only cases exceeding the alarm levels are recorded, and the recorded results can be displayed in the form of valuable statistics for effective management of potential epidemics.

Neutron System for Moisture Measurement

Moisture content measurement system LB 350, manufactured by Berthold, is mainly used in applications where conventional sensor technologies are not applicable because of the conductivity or the chemical properties of the material being measured. “For continuous humidity measurement of solids, the LB 350 uses the neutron deceleration method. It uses the effect of neutron scattering as a result of the interaction of high-energy (fast) neutrons with the nuclei of hydrogen atoms in the material being measured”, the Process control department explained.

The measurement system is based on a source emitting a cloud of fast neutrons. After their interaction with the water molecules in the material being measured, the decelerated neutrons are measured with a special detector that is sensitive to only slow neutrons. Since the number of slow neutrons corresponds to the hydrogen content, the neutron technology is a reliable technical solution for measuring the moisture content of a product.

 “Neutron technology does not depend on the chemical or physical bonds between the water molecules in the measured volume”, commented Mariela Mladenova, a specialist in the field. “It is not affected by temperature, pressure, conductivity, color, pH value, electrolyte content or different particle sizes. Through it, even the content of deep-frozen water can be accurately estimated” the company experts added.

Measurement through the LB 350 system is accomplished by installing a bunker probe inside the tank or a surface probe against the wall of the vessel with the product being measured, depending on the specifics of the application.


The surface probe is mounted directly on the outer wall of a bunker. It is capable to irradiate up to 20 mm thick steel walls. However, the best measuring accuracy is achieved by using Berthold’s specifically designed mounting frame, which is installed in an opening in the wall. The mounting frame is extremely robust due to the wear-resistant ceramics surface and allows for a quick and easy installation of the probe.


The probe is mounted in a dip pipe made from steel or ceramics. Typically, this dip pipe is inserted in the outlet section of the bunker, so that the probe is fully surrounded by bulk material. Due to the optimum position of the probe inside the material flow, a highly representative measurement is achieved.

The LB350 system has proven it’s reliability and extremely accurate operation in multiple hard applications, including moisture measurement of sand int concrete or glass industry, as well as humidity determination of coke and sinter mixtures.
