Why Use a Platinum Sensor

The sensing wires in an RTD can be made of nickel, copper, or tungsten, but platinum (Pt) is by far the most popular metal used today. It’s more expensive than other materials, but platinum has several characteristics that make it particularly well suited for temperature measurements, including:

• Almost linear temperature–resistance relationship
• High resistivity (59 Ω/cmf compared to 36 Ω/cmf for nickel)
• Non-degradable electrical resistance over time
• Excellent stability
• Very good chemical passivity
• High resistance to contamination

The Difference Between Pt100 and Pt1000 Sensors

Among platinum RTD sensors, PT100 and PT1000 are the most common. Pt100 sensors have a nominal resistance of 100Ω at ice point (0°C). Pt1000 sensors’ nominal resistance at 0°C is 1,000Ω. Linearity of the characteristic curve, operating temperature range, and response time are the same for both. The temperature coefficient of resistance is also the same.
