Temperature Sensors

Thick-film chip resistors based on Ruthenium Oxide are effective low-temperature thermometers.

Entropy offers several types of RuOx sensors for different temperature ranges and applications in high magnetic field.

Housing: The standard sensor housing is made of pure silver or copper. A minimal amount of pure epoxy is used in the construction to avoid heat-capacity anomalies from epoxy fillers. The sensor has an integrated SMD connector for easy and reliable electrical connection.

Other housing options such as chips on silver foil or naked are available on request.
