We produce sensors and sensor platforms using thin film technology. We proudly cooperate with leading Czech universities and scientific workplaces.
Already a traditional part of the product range of TESLA BLATNÁ a.s. are sensors and sensor platforms produced by thin-film technology, on the design and development of which we have long-term cooperation in a number of projects with leading Czech universities and research institutes. The production of these sensors and sensor platforms takes place in fully equipped facilities of our own clean labs. The main product of the company's portfolio in this area are platinum temperature sensors, which are complemented by the offer of individual unique sensor platforms.
Temperature sensors from our production are used not only in wide range of industrial applications, but also in science and research. Sensor platforms are used as the basis for the construction of wide range of sensors, especially sensors for gases and dangerous substances. They are used both in the production and development of new sensors. Based on an individual approach to customers, we can design and manufacture sensor platforms according to specific requirements.
The basic structural element of sensors and sensor platforms is a ceramic substrate made of Al2O3. With the sputtering technology of thin metal layers, photolithography, wet and dry etching, we are able to realize various resistance and electrode structures. We will present the basic structural parts on the platinum temperature sensor.
The thin layers department at TESLA BLATNÁ has long history and follows the construction of planar microwave structures. Today, the production and development program has shifted to sensor platforms and sensors on these structures.
We produce platinum temperature sensors (resistance temperature sensors) for industrial and scientific use. Temperature sensors are constructed as thin-film resistance sensors on a ceramic substrate. This design has numerous advantages over classic sensors made of wound platinum wire. The construction of the thin film sensor is simpler, has higher mechanical resistance and offers wider variability in use. Platinum has excellent physical parameters for the purposes of a resistance temperature sensor, the usable temperature range is from -200 °C to 1000 °C. The manufactured platinum sensors have a temperature coefficient (TKR) of 3850 ppm/K and correspond to the EN 60 751 standard. The basic nominal values of the manufactured temperature sensors are 100 and 1000 Ω.
Platinum resistance temperature sensor on ceramic substrate with a nominal value of 1000 Ω at 0 ˚C. Silver wire leads are welded to the sensor. PT1K temperature sensors are available in accuracy classes according to the corresponding standard ČSN EN 60 751.

In addition to the basic range of temperature sensors, we also produce their modifications based on customer requirements. We will custom produce temperature sensors with different ohmic resistance values, different dimensions and different supply wires. The most frequently requested modification are different dimensions and a resistance value of e.g. 500 Ω.
The KBI2 platform is a multisensor structure that consists of a Pt1K temperature sensor, a heating element and an interdigital electrode structure. All elements are formed by a thin layer of platinum on a ceramic substrate. The heating element and the temperature sensor are protected by a thin covering insulating layer. Sensitive layers can be deposited on an unpassivated interdigital structure by screen printing, spin-coating, drop-coating, etc.
KBS4 is a double-sided sensor platform that consists of platinum electrodes of an interdigital structure on the front side of the ceramic substrate and a platinum heating element on the reverse side of the ceramic substrate. By uniformly covering the surface of the platform with a heating element, a homogeneous temperature field on the surface of the platform is ensured. Continue by scrolling.. The individual structures of the platform are made of a thin platinum layer. The supply wires are contacted to the platform on the face side on opposite edges. Conductive contact with the heating element on the reverse side of the platform is ensured by plating with platinum through holes in the ceramic substrate. The heating element is protected by a covering insulating layer. Sensitive layers can be deposited into the space of the non-passivated interdigital structure by various methods (screen printing, spin-coating, drop-coating, ...)
Gold interdigital electrodes are applied to the ceramic substrate, on which sensitive layers can be applied using thick-layer or thin-layer technology. The electrode system enables the use of various sensitive layers. The topology of the interdigital electrodes can be modified according to specific customer specifications.
The humidity sensor BI2H is a semiconductor sensor designed for measuring relative humidity. The physical principle of the measurement is based on the properties of an organic semiconductor, which changes its impedance due to humidity. The changing impedance of the sensitive layer due to humidity can already be easily evaluated electronically.
In addition to the basic range of temperature sensors, we also produce their modifications based on customer requirements. We will custom produce temperature sensors with different ohmic resistance values, different dimensions and different supply wires. The most frequently requested modification is different dimensions and a resistance value of e.g. 500 Ω.
We also produce sensor platforms in modifications based on the requirements of individual customers. We deposit electrode structures on various types of substrates, most often, in addition to ceramics, we realize structures on silicon and glass substrates. We can design different arrangements of interdigital electrodes and heating element.
We also offer our development and production capacities for manufacturing of final sensors. In this area, we implement various conductivity sensors, sensors using our heating elements, electrochemical sensors, etc.
