Platinum RTD Elements
Copper stands out as an important material in temperature sensors for several reasons: high thermal conductivity, excellent stability and reliability, versatility in different types of sensors, and attractive cost-effectiveness.
10Ω copper temperature sensor at 25°C
These sensors are manufactured with a ceramic core where the sensing element, which is a copper wire, is wound. This assembly is then coated with insulating resin for high temperatures.
Copper temperature sensors are designed to have a nominal resistance of 10Ω at 25°C and comply with a temperature coefficient α = 0.00427 Ohms/Ohms/°C.
The most commonly used tolerance class for copper sensors is ±0.2% at 25°C.
Applications from -190 to 260°C
