INTRODUCTION
The SEM203/TC Temperature Transmitter has
incorporated the latest digital technology to provide
accurate and reproducible conversion of
thermocouple signals to 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
a millivolt simulator and push of the button on the
transmitter, configuration is complete.
High accuracy and drift-free linearisation along with
quick push button calibration make the SEM203/TC
the ideal choice for converting thermocouple signals
to isolated 4-20 mA.
An on-board LED indicates the successful
completion of configuration procedure and also
provides instant indication of the sensor's fault.
