Is your temperature sensor failing in extreme cryogenic conditions?

IST AG (part of the Endress+Hauser Group) has introduced its latest innovation: the iST Cryo-Sensor, engineered to deliver reliable and accurate performance in the most demanding low temperature environments. At temperatures approaching 15 K, temperature sensors encounter fundamental limitations such as reduced sensitivity, strong non-linearity, thermomechanical stress, and long-term instability, all of which can significantly affect measurement accuracy and reliability.

However, the iST Cryo-Sensor provides excellent signal stability, a favourable cost-to-performance ratio, and reliable measurement performance across a wide temperature range from 15 K to 473 K.

The iST Cryo-Sensor is based on thin-film sensing technology optimized for cryogenic operation, ensuring stable, reproducible, and reliable measurement performance under extreme low-temperature conditions.

It is designed for use in applications requiring precise temperature monitoring, including scientific research, medical technology, and cryogenic systems such as liquefied gas storage or transportation.

Key Features:

• Resistance: 1000 Ω
• Temperature Range: −258 °C to +200 °C
• Tolerance: IEC60751 F0.15 from −200 °C to +200 °C;  ±3 K from −258 °C to −200 °C (batch-calibrated);  ±0.2 K from −258 °C to −200 °C (individually calibrated)
• Technology: Thin-film platinum RTD

Application Focus:
Liquid hydrogen (LH₂) systems, cryogenic process monitoring and control, scientific research and laboratory instrumentation, medical and life science cryogenic applications, aerospace and space applications, industrial gas handling, low temperature material testing and characterization

Depending on specific application requirements, iST offers both cost-effective standard solutions and individually calibrated sensors. If you are interested in testing this sensor, please download the datasheet or contact iST for samples.
