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 and the 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 technology, sensors can be monitored continuously, and erroneous measuring locations can be identified immediately.
Additionally, the T38 transmitters also have numerous sophisticated supervisory functionalities such as monitoring of the sensor lead resistance and sensor break monitoring in accordance with NAMUR NE89 as well as monitoring of the measuring range. 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.
