Passive duct temperature sensor PT1000
Product description
The DUTSN series are passive PT1000 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 1.000 kΩ.
Additional specifications and description
How does it work?
This temperature probe measures ambient temperature via a platinum element (PT1000). This sensor element has an electrical resistance of 1 Kohms at 0 °C. It has a positive temperature coefficient. This means that the resistance increases when the ambient temperature increases. Any device with an input for 'PT1000 passive temperature sensors' can read out the measured temperature.
How to connect?
The sensor element is built-in in a plastic tube housing. The sensor element can be connected via a terminal block in the plastic enclosure. The longer the cable length, the higher the influence of the resistance of the cable on the measurement readout. This sensor doesn't require a separate power supply.
Temperature probe for air ducts
The platinum sensor element is built-in in a plastic tube housing. The tube has a length of 250 mm. It can be installed in air ducts with a diameter larger than 300 mm. It offers an IP30 protection degree against ingress of dust and moisture.
