Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If assembled into a complete probe with housing and connectors
Complete temperature sensors with automatic controls fall under automatic regulating instruments in 9032, not resistor parts.
If imported as discrete electronic components without specific 8533.40 designation
Other electrical machines and apparatus for sensing may apply if not specifically identified as parts for variable resistors/thermistors.
If designed primarily for use in transformers or inductors
Parts of electrical transformers include temperature reactive elements specific to those machines.
