Temperature measurement is one of the most important physical parameters when determining quality, accuracy and reliability of processes not only in industrial use, but also in almost all human activities. Temperature sensors are produced with different technologies to fit specific application requirements.

IST AG has concentrated one part of the development and manufacturing on high-end thin-film temperature sensors. This know-how is partially derived from the semiconductor industry and allows us to manufacture sensors with high accuracy, excellent long-term stability, high reliability and repeatability within a wide temperature range from -200 °C up to 1000 °C. Because of very small dimensions and low thermal mass, the thin-film temperature sensors exhibit a very short response time.

It is no secret that customers over time require a better long-term stability with increasing accuracy in a wider and wider temperature range. Due to the excellent long-term stability of the IST AG thin film temperature sensors it is possible not only to guarantee the standard class B (IEC 60751; F 0,3), class A (IEC 60751; F 0,15) or class 1/3 IEC 60751; F 0,1, but also even more precise accuracy classes such as 1/5 IEC or 1/10 IEC. IST AG manufactures and supplies various sensor elements in accuracies measured in class 1/5 IEC, 1/6 IEC or even 1/10 IEC over a wide temperature range.

Additionally, IST AG also offers the customers a special nominal resistance at e.g. 0 °C or to measure the sensors in shifted tolerance bands such as (0 mK to 300 mK) at 0 °C instead of e.g. (-300 mk to +300 mK) at 0 °C to compensate a shift of Ohmic values during the assembly process by the customer.

The IST AG characteristic curve is based on more than 20 years of measuring experience and exactly describes the behavior of the IST AG platinum temperature sensors. With this knowledge it is possible within a specific temperature range to measure individual sensor elements and extract individual polynomial values R(0), A and B from a polynomial of second order of type (R(T) = R0 (1 + A x T + B x T2)) to achieve the highest achievable accuracy.

Furthermore, we also offer sensor elements in pairs with custom specific deviations (max.) or sensors in groups based on temperature coefficient and custom specific deviation (max.).

Every year, we manufacture more than 10 million sensors from a portfolio covering more than 4000 different products.

The Process of CSPAB (Custom-Specific Product Approval Board)

Customer specific enquiries usually start by taking contact to one of the IST AG sales specialists. The sales specialist discusses the specific requirements and application together with the customer. Subsequently the project is discussed internally with relevant R&D engineers and submitted to the CSPA board. The CSPA board consists of IST AG production and quality engineers, developers and sales specialists contributing with specific product knowledge and expertise. The feasibility of the submitted solution and its product requirements are evaluated by the board to either approve or determine if further clarification is needed. Only when the customer is satisfied with the proposed solution, samples are produced for customer validation. When successful, IST AG will commence production and deliver the parts in a short time.

Each year more than 200 new sensor solutions, approved by the CSPA board, are manufactured and added to the portfolio based on specific customer requests and applications.
