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.
The 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, extended 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
