Digital temperature transmitter
With HART® protocol, head and rail-mounted version
Model T38
These temperature transmitters are designed for universal
use in the process industry. They offer high accuracy through
sensor-transmitter matching, highest reliability and excellent
protection against electromagnetic influences. Via HART®
protocol, the T38 temperature transmitters are configurable
(interoperable) with a variety of open configuration tools. In
addition, the T38 temperature transmitters, via the WIKAsoft
TT configuration software with model PU-548 programming
unit, can be parameterised very easily, quickly and with a
clear overview.
Besides the selection of the sensor type and the measuring
range, the software enables the error signalling operation,
damping, several measuring location descriptions and
process adjustment to be stored.
he T38 transmitters offer a wide range of sensor connection
combinations.
Through the configuration of a sensor with redundancy (dual
sensor), on a sensor failure it will automatically change over
to the working sensor. Furthermore, there is the possibility
to activate sensor drift detection. With the WIKA True Drift
Detection, sensors can be monitored continuously, and
erroneous measuring locations can be identified immediately.
Additionally, the T38 transmitters also have numerous
sophisticated supervisory functionalities. In addition, extend
ed diagnostic functions in accordance with NE107 are
integrated and extensive cyclical self-monitoring functions
are carried out, which contribute to the high level of system
security
