| Monitoring functionality when 2 sensors have been connected (dual sensor) | Redundancy | In the case of a sensor error (sensor break, lead resistance too high or outside the measuring range of the sensor) of one of the two sensors, the process value will be only based on the error-free sensor.Once the error is rectified, the process value will again be based on the two sensors, or on sensor 1. |
|  | Ageing control (sensor drift monitoring) | An error signalling on the output is activated if the value of the temperature difference between sensor 1 and sensor 2 is higher than a set value, which can be selected by the user. This monitoring only generates a signal if two valid sensor values can be determined and the temperature difference is higher than the selected limit value. (Cannot be selected for the &#x27;Difference&#x27; sensor functionality, since the output signal already indicates the difference value). |
