AccuMac AM1643 Specifications

AM1643 Full Immersion PRT

HIGHLIGHTS

OVERVIEW

FEATURES

 Transition junction and lead wire

can withstand high temperature
up to 420°C

 Short term stability: 0.02 °C
 Temperature range: 0 °C to 420 °C

AM1643 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.

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.
