The AM41640 series precision Industrial PRTs (IPRTs) are rugged probes with excellent accuracy and stability. They cover a wide range of temperatures from -200°C to 670°C, with an amazing accuracy of <0.035°C at 0°C, a short term stability of <0.01°C, and a fast response time of 5 seconds. All of these probes include ISO/IEC 17025 accredited calibration.
To reach the best performance in stability and repeatability, the wire-wound sensing element is specially designed to protect the platinum sensing wire from contamination at high temperatures. A unique support structure and filling material provide the best balance among the hysteresis effect, mechanical shock and thermal shock performance. All of these probes conform to the standard 385 curve so the resistance ratio of the PRTs follows the DIN/IEC-751 curve precisely.
