Innovative Sensor Technology PW Series Platinum RTD Temperature

Innovative Sensor Technology PW Series Platinum Resistive Temperature Devices (RTD) have been developed as an alternative to traditional wire-wound sensors. The PW series sensors combine the advantages of high accuracy and precision in wire-wound sensors with the advantages of thin-film sensors that offer robustness, small dimensions, and low hysteresis at a cost-effective price level. Compared to a standard thin-film sensor measuring up to +300°C in IEC 60751 F0.15 (Class A), the PW sensors measure with high accuracy up to IEC 60751 F0.15 (Class A) within a wide operating temperature range from -200°C to +600°C. As an additional feature, IST PW sensors are available in round ceramic housing.
