How many thresholds can be set?
Danfos limiters for fixed-end ropes are available in two lines: with one threshold; with two thresholds. Two-threshold models are useful when there is a need to detect the reaching of two different thresholds. For example, if you want to use the first threshold to detect when 90% of the system flow rate has been reached (and connect this threshold to a flashing light), and to use the second threshold to block the motor.
