Resistance thermometer sensing elements

All Pt100 sensors comply with IEC751 and, depending on construction, are available in Class A, B and 1/3, 1/5 and 1/10 DIN tolerances. Dimensions range from sub-miniature to 50mm length to suit any application and optional extended terminations are available to order.

The new, low-cost surface mount device provides an accurate and stable alternative to thermistor beads with the advantage of a universal world standard Pt100 interface with a virtually linear characteristic over a wide range, -50oC to 130oC.

A range of -196oC to 1000oC is spanned by the range of sensing elements depending on the configuration and Ro value (Pt100, Pt200, Pt500 and Pt1000).
