INNOVATIVE SENSOR TECHNOLOGY IST AG

The IST AG PW RTD sensor has been developed as an alternative to the traditional wire-wound sensors. The PW sensor combines the advantages of high accuracy and precision of the wire-wound sensors with the advantages of thin-film sensors that offer robustness, small dimensions and very low hysteresis at an optimal price level. Compared to a standard thin-film sensor measuring up to +300 °C in IEC 60751 F0.15 (IST AG reference class A), the IST AG PW sensor measures with high accuracy up to IEC 60751 F0.15 (IST AG reference class A) within a wide operating temperature range from -200 °C to +600 °C. Due to the special construction and stable characteristics curve, the IST AG PW sensor is also suitable for low temperature applications. As an additional feature, the PW sensor is available in round ceramic housing with the same dimensions as a traditional wire wound sensor, meaning easy interchangeability into existing temperature applications.

The SFS01 is particularly suitable for low flow velocities up to 3.5 m/s (in gases). It shows very fast measurement results of the flow rate as well as the flow direction. The Silicon Flow Sensor SFS01 offers three main characteristics: — Very fast response time <5 ms — Very low energy consumption — Easy system integration including temperature compensation Well-adapted channel geometries allow the performance of the sensor to be optimally aligned to the desired application. The SFS01 flow sensor is ideally suited for space-limited applications, but can also be easily upgraded to complete ready-to-use systems. Suitable application areas for the SFS01 flow sensor are flow measurements in battery-operated / portable devices, air conditioning technology (HVAC), automation technology as well as process and control engineering.

IST AG offers ESCC qualified thin-film Pt temperature sensors, applicable from -200 ° C to +200 ° C. The sensors provide stable measuring results at 70,000 cycles from -200 ° C to +200 ° C, which proves that the sensors are resistant against thermal cycles. The temperature coefficient of resistance (TCR) remains very stable, also the sensors proved a high stability regarding drift. Further advantages of the sensors are the small size (L x W x H: 2.3 x 2.0 x 1.1 mm), the light weight and the robustness due to the lack of moving parts. IST AG is the first, and currently also the only supplier providing ESCC qualified Pt temperature sensors. The RTDs are available with different resistances ranging from Pt100 to Pt2000. They are offered with tolerance class B (IEC 60751 F0.3). The temperature sensors are available both as Engineering Model (EM) or as Flight Model (FM). We also offer customization of the sensors, e.g. extended wires (with an ESCC qualified wire).

Stable and robust humidity sensors with ultra-fast response time are often required in applications involving meteorology – not only in normal conditions, but also under elevated environmental constraints such as extremely low temperatures, high radiation levels and under extreme condensation. Such applications need fully tailored solutions, such as those provided by the Innovative Sensor Technology IST AG P14 Rapid. The P14 Rapid humidity sensor combines speed and full range operation in an ideal way.

The IST AG P14 2FW Thermo was designed especially for dew point applications and humidity generators. The favorable one-chip solution consists of a capacitive humidity sensor, based on the standard P14 sensor, together with a heating element, which, at the same time, works as a valid Pt100 sensor. The sensor achieves outstanding measurement accuracy due to the optimal thermal coupling which enables a fast recovery time. Due to heating from the Pt100, humidity is quickly released and enables fast re-measurements after condensation. Furthermore, the Pt100 sensor heats out gases or vapors from the polymer, which might cause a drift of the humidity signal. The P14 2FW Thermo humidity sensor is capable of measuring 0 % RH to 100 % RH (maximal dew point +85 °C) with a capacitance of 150 pF ±50 pF (at 30 % RH and +23 °C) and operates within a temperature range of -50 °C to +150 °C.
