  • -328 to 788°F (-200 to 420°C) temp range
  • ±0.04°C drift rate
  • 100Ω nominal resistance
  • 0.25in (6.35mm) diameter

The AccuMac AM1640 precision industrial PRT features an accuracy of ±0.035°C at 0.01°C and a short term stability of ±0.01°C. The sensing element is designed to protect the platinum sensing wire from contamination at high temperatures, giving the device a high level of stability and repeatability. A uniquely designed support structure and filling material provides an excellent balance between the hysteresis effect, mechanical shock, and thermal shock performance.

These probes conform to the standard 385 curve so that the resistance ratio of the PRT follows the DIN/IEC-751 curve precisely.
