INTRODUCTION
The SEM203P Temperature Transmitter has
incorporated the latest digital technology to provide
accurate and reproducible conversion of 2 or 3-wire
RTD signals to industry standard 4-20 mAoutput.
This, in-head-mounted transmitter, is unique, because
it does not need a PC, solder linking or a
potentiometer for configuration. By generating the
required low and high signals with a calibrator or an
RTD simulator and push of the button on the
transmitter, configuration is complete.
High accuracy and drift-free linearisation coupled with
flexibility of reduced stock holding and quick push
button calibration make the SEM203P the ideal choice
for converting RTD outputs to 4-20 mAsignals.
An on-board LED indicates the successful completion
of configuration procedure and also provides instant
indication of the sensor's fault.
