Sensors used for Temperature

Temperature Sensors

IST USA Division is a world-class manufacturer of thin-film RTDs in platinum and nickel, as well as temperature sensor ICs.

Advantages of Thin-Film RTDs

When looking at temperature measurement technologies, thin-film RTDs have a number of advantages over thermistors and wire-wound RTDs. Thermistors have a much smaller temperature range and tend to drift over time. However, thin-film RTDs can operate in the harshest conditions while experiencing minimal drift. Wire-wound RTDs can be susceptible to vibration and are expensive to produce, while thin-film RTDs are much more robust, more affordable, and offer more packaging options.

If you are dealing with applications that require high accuracy in extreme conditions, IST thin-film technology is the best option.

Temperature Sensor Types

Our temperature sensor portfolio includes:

  • Platinum
    IST platinum temperature sensors are designed with the highest quality materials, allowing them to operate within a temperature range of -200°C to +1000°C.

  • Nickel
    IST nickel temperature sensors provide solutions for precise temperature measurement, having a higher resolution within a smaller temperature range.

  • TSic
    The TSic product family offers not only excellent accuracy, but also long-term stability.

Our Technology

The core technology of all IST products is thin-film deposition, in which a thin layer of metal is deposited onto a ceramic substrate.

This technology allows for the production of extremely small sensors with enhanced operational capabilities such as:

  • Improved response times
  • Robustness
  • Packaging versatility

IST thin-film technology is second to none for applications requiring long-term stability and accuracy in wide temperature ranges. Using our expertise in thin-film deposition, we develop measurement solutions that are consistent and reliable.

IST AG has one of the best equipped front-end production lines for thin-film sensors, operating in clean rooms to class 1000. The fully automatic assembly technology ensures the highest quality product with an optimal price-performance ratio. Precise measuring instruments in our laboratories allow for the calibration of our products in the areas of temperature, humidity and flow.
