Sensors coherence
The measurement results of the two channels in redundant configuration are
unlikely to be exactly the same (even with equal sensors) due to the tolerances in
the signal chain. The tolerable difference between the channels can be set-up in
the option Sensors Coherence.
The following parameters are provided to compensate for permissible differences
between readings of identical sensors.
• Maximum deviation threshold: Maximum tolerable difference between the
measurements of the two sensors in the unit defined in the parameter
Measurement unit.
• Maximum timeout threshold: maximum time to exceed the gap in seconds.
For additional explanation see the following diagram.
