INTRODUCTION
The SEM210 Smart Temperature Transmitter provides
accurate and reproducible conversion of commonly
used temperature sensors, slide-wire transducers or
millivolt signals to industry standard 4-20 mA output.
The versatility of this temperature transmitter makes it
the ideal choice for every temperature application,
resulting in lower stock holdings and greater operation
flexibility.
The transmitter can easily be programmed using a
software package running under 'Windows' ™. Sensor
type, temperature range, filter factor, linearisation
scheme, temperature offset, burnout option,
temperature unit and the device tag number can be
selected without the need for recalibration.
Sensor referencing feature enables the transmitter to
be accurately matched to a particular sensor. A user
programmable offset is available to remove any
system error or to shift the temperature reading in
either direction. Four selectable settings are provided
to filter and remove any incoming noise from the
sensor.
Isolation is also a standard feature, removing all
ground loop effects as the input is electrically and
physically isolated from the loop power supply. The
use of two microprocessor results in error-free data
transmission across the isolation barrier.
The transmitter is protected against reverse
connection, so that incorrect output wiring results in
nearzero current flow in the loop.
