AM1642 Full Immersion PRT



Overview

AM1642 full immersion PRT features a unique design that allows for the users to apply the probe together with its lead wire in a high temperature environment such as ovens or furnaces etc. It covers a wide range of temperature from 0 °C to 420 °C with amazing accuracy of ±0.04°C at 0 °C, short term stability of ±0.02°C and fast respond time of 5 seconds. The standard length is 4-inch but customized dimensions are available per request. Customized length can range from 2 inches to 12 inches.   
To reach the best performance in stability and repeatability, the wire-wound sensing elements are specially designed to protect the platinum sensing wire from contamination at high temperature. A unique support structure and filling material provide the best balance among the hysteresis effect, mechanical shocks and thermal shock performance. This probe conforms to the DIN/IEC-751 curve precisely
