1 Introduction
1.1 Main Application
AM1640 Precision Industrial Platinum Resistance Thermometer (PRT)
is an interpolating instrument converting temperature to resistance. It
works together with readout device to measure temperature or change
of temperature. It has wide applications for dry-wells or temperature
baths.
1.2 Main Features
High accuracy: 0.035 ºC at 0°C
Temperature range:
:
-200 °C to 420 °C
Durable and shock resistance
1.3 Calibrations
It is recommended to calibrate this PRT annually over the full
temperature range. In between annual calibrations, user can check the
drift rate by comparing Rtpw against the last calibration results. Refer
to specifications section for normal drift rate.
