Vector-1
Vector 1 - Plovdiv produces various types of sensors - temperature, humidity and level sensors.
The temperature sensors are: semiconductor sensors to 125 ? C with analog or digital output;  RTD  Pt100, class A and B ( DIN EN 60751 ) up to 600 ?C; thermocouples J and K, class 1, 2 ( ASTM E230)  up to 1050 ?C. The construction of sensors is from stainless steel. According to the construction these sensors are with PVC, silicone or glass insulated cable; with protection head; temperature inserts; special design on request.

Vector 1 offer noncontact infrared temperature sensors with different ranges, outputs and constructions. Relative humidity sensors for air and gasses have a range from 0Е100% RH and high accuracy. Operating temperature:  (-20 ... +85) °C. The humidity sensors have built-in sensor for temperature compensation and are applicable to dusty environments.

Vector 1 also produces conductive and float level probes. Conductive sensors have different design and lengths of stainless steel electrodes. Float level switches consist of reed relays, built into the stem of the level sensor, that are triggered by the movement of a float. The floats with a permanent magnet are made of polypropylene or stainless steel. They are used for measuring the level of a relatively clean fluid, and are particularly useful in the foaming liquids.

Bulgaria has an important place in LEM’s development strategy

Borjan Borisov, General Manager of LEM Bulgaria

Mr. Borisov, the first plant of the Swiss company LEM in Bulgaria started its production at the end of October 2013. What is its focus?
LEM is the global market leader in providing innovative and high quality solutions for measuring electrical parameters. Voltage and current transducers are used in a wide range of industrial and automotive markets. In fact, we come across LEM sensors everywhere in our everyday life, but we don’t always see them.

LEM sensors are embedded in almost all modern household appliances, elevators, trains and cars, as well as in systems for the production of green energy. So this is the focus of the Bulgarian factory - the production of a wide range LEM sensors.

What had prompted the decision for this investment? Why did Bulgaria attract the attention of manufacturers such as LEM?
LEM’s decision to invest in Bulgaria is not accidental. The main advantage is that in recent years the country has been recognised as one of the most financially stable countries in the European Union. This is due to the fact that Bulgaria has a currency board and the Lev is pegged to the Euro. This results in less dependence on currency fluctuations and risks for the business.

What’s more, Bulgaria is a country with traditions in similar kinds of production, so technicians used to such a high engineering culture will be able to offer new ideas and improvements for the future of the company.

Last but not least, the production costs in Bulgaria are not comparable to those in Western Europe or Japan, which is leading to increased competitiveness.

Where is the new production facility and what is it capacity?
The new production base is located in Sofia, Iliyantsy district. LEM’s plant has nearly 5,000 square meters of production area with developed infrastructure which meets the current requirements for  modern electronics production. Currently LEM Bulgaria has nearly 50 employs, but in the next few years their number will increase to 400.

What advanced technologies and equipment are currently implemented in the production and from which suppliers?
Our first production facilities were transferred from Switzerland. The machinery and equipment are at a very high technology level - some are fully automatic, others are semi-automatic, but all of the process is fully controlled. And as for our suppliers - we will naturally continue with those outside Bulgaria, but in parallel we will work on the evaluation and validation of local ones.

What is the planned market for the products manufactured in the new plant?
Like I said, LEM is a world leader in the field and has production facilities in Switzerland, Japan, China, and now in Bulgaria. At the same time we have a trade network and offices worldwide. This means that we produce and export LEM sensors worldwide.

What is the role of this investment in the overall policy of LEM? What are your intentions for the development of the local market?
LEM Bulgaria is the newest factory of LEM Holding SA and will be developed to its full capacity in a relatively short time. This means that LEM Bulgaria has an important place both in the present and in the future strategy of LEM. Gradually LEM Bulgaria will become the basis for future expansion of both our European and global markets. This, together with good technical potential, determines LEM Bulgaria as a key factor in the future of LEM.
