1049 Technical Manual 2
1. Introduction
The 1049 is a portable precision simulator for PT100 0.3850 platinum resistance elements
used for accurate temperature measurement
It follows the PT100 scale from -200°C to +800°C with 23 set points. High performance
metal film resistors are used throughout which ensures a good temperature coefficient and
long term stability.
The specification is in accordance with DIN EN 60751 (ITS 90).
Offering high accuracy across the full operating range of PT100 devices it exceeds the
performance of Class A & B.
The 1049 will be of particular interest to those operating in the –60 to +60 °C range where a
performance exceeding Class A (e.g. better than +/- 0.15°C at 0 °C), is required.
Since the 1049’s output is a purely passive resistance it will operate with all types of PT100
measuring equipment including the live systems using pulsed or interrupted excitation
current.
