Copper & Platinum RTD Assemblies

The RTD Sensor is either a platinum or copper wire wound element which changes resistance proportional to temperature change. the resistance change per degree of temperature change is nearly linear throughout the temperature range of the sensors, providing a very accurate reading. The 3 wire sensor is the most common in industry and almost totally compensates for the lead wire length. Four wire sensors are used to eliminate all effects of lead wire resistance in metrology applications.

Reliability ± Less than 0.01 °C or Better

Stability Drift is less than± at 0 C after one year normal service within rated temperatures.

Time Constant 5 seconds in water at 3 feet /second

Self-Heating 28 mW/ °F in water at 3 feet /second

Vibration Assembly construction withstands 50 Hz to 2000 Hz at 20 G's minimum per MIL-STD-202C, Method 204A, Test Condition D.

Shock Element construction withstands minimum 100 G's since wave shock of 8 millisecond duration, three blows applied to each axis.

304 Stainless Steel : Good oxidation and corrosion resistance in a wide range of industrial environments. Subject to carbide precipitation, which can reduce corrosion resistance in the 427°C-537°C range. Good mechanical properties from -185°C to 788°C. Regarded as the standard protection tube material.

316 Stainless Steel same areas of application as 304 Stainless Steel. Improved resistance to mild acid and pitting corrosion.

Inconel Superior resistance to sulfur and reducing conditions.
