Freely programmable monitoring functions
Monitoring of the measuring range:
If this function is activated, an error is signalled on the current loop (< 3.6 mA) if the
measured value is either below or over the limits of the measuring range.
Freely programmable monitoring functions when 2 sensors have been connected
(dual sensor)
The following options are not available in the difference mode!
Redundancy/hot backup:
In the case of a sensor error (sensor break, line resistance too high or measured value
outside the measuring range of the sensor) of one of the two sensors, the process value
will be the value from the working sensor only. Once the error is rectified, the process value
will again be based on the two sensors, or on sensor 1.
Ageing monitoring (sensor drift monitoring):
An error signal 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 “Difference” sensor functionality, since the output signal
already indicates the difference value).
6.3.1 Configuration via the PC
To configure the transmitter, both configuration software and a HART
®
modem are needed.
WIKA offers 3 different HART
®
modem models for this.
