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.
