Copper temperature sensors are generally used in less critical industrial applications because they are not as accurate as platinum sensors, but their advantage is low cost and linearity.

Copper temperature sensor 10Ω @ 25 °C

Copper is consider a material that does not withstand well in oxidizing atmospheres.The fact of low resistance and an over a long period of exposure a possible oxidation can decrease reading accuracy in oxidizing atmospheres. On the other hand, it is commonly used in many applications free of oxidizing atmospheres.

Usually they are manufactured with some core insulating material, which can be ceramic, epoxy resin with fiberglass, mica, etc.

The external encapsulation can also be PTFE (Teflon), epoxy resin with fiberglass, metal sheath and other material depending on the working temperature of the application.

The copper sensors were developed and determined to have a resistance of 10Ω at 25 ° C and comply with a temperature coefficient α = 0.00427 Ohms/Ohms/°C.

The most commonly used copper sensor tolerance class is ± 0.2%.

Applications from -190 to 260 °C

Their applications may be diverse although it is commonly used to determine the operating temperature in stators windings of motors and generators.
