The DUTSN series are passive PT500 duct temperature sensors which are based on the advanced thin film technology of the platinum sensitive element. These temperature sensors are optimised for temperatures measurement in air duct systems and they provide temperature measurements with high stability and accuracy. An integrated shield connection makes these sensors suitable for applications where grounded shielded cables are required. They can be connected via a terminal block (1,5 mm²). At 0 °C the resistance is 500 Ω.
