The thinnest wired temperature sensor you have ever seen!

The world's smallest wired temperature sensor with extremely fast response time has a width of only half a millimeter and fits into tiny spaces with a diameter of 0.8 mm. 

With a round ceramic housing it has a diameter of 1.2 mm and is 10 mm lon.


ESD optimized temperature sensors

To avoid the costly consequence caused by ESD, IST AG is committed to continued optimization and development of ESD-optimized temperature sensors to strengthen the stability of our customers’ assembled systems. 

With optimized design and new process technology we offer platinum temperature sensors with outstanding ESD resistance. The designs have been tested according to European Union Standards, the IEC/EN61000-4-2. 

Thanks to a state-of-the art in-house ESD laboratory, we are able to test all our sensors internally according to international standards.

Nickel Temperature Sensors

Nickel Temperature Sensors

Our nickel RTD temperature sensors come with an operating temperature range of -60 °C to +300 °C. They are characterized by a simple linearization and a steep characteristic curve. Suitable for e.g., HVAC applications, nickel RTD sensors offer an excellent long-term stability and easy interchangeability. IST AG’s nickel temperature sensors are available with various TCRs such as 6180 ppm/K (Nickel ND), 5000 ppm/K (Nickel NL), 6370 ppm/K (Nickel NJ), 6720 ppm/K (Nickel NA) and Balco.
