Transmitters convert the sensor signal into a standardized, temperature-linear current or voltage signal.
The advantage of two-wire transmitters is that they amplify the signal, making it much less sensitive to
interference.
Several design types are available for positioning the transmitter as required. To make the signal less
susceptible to interference, the section covered by the non-amplified signal should be kept as short as
possible. For this reason, the transmitter can be mounted directly in the thermometer, for example in the
terminal head. However, while this may be the optimal solution, it may be rendered unviable by design
constraints or the fact that the transmitter may be difficult to access in the event of a malfunction. In such
cases, a transmitter for mounting rail installation in the control cabinet is used. In this case, the advan-
tage of having better access comes at the expense of a longer section that the non-amplified signal has
to cover. If required, a transmitter can also be latched into the line.
NOTICE!
