Steady State Load
Applicable for Posidapt
–Super and Ultra
This parameter is used for steady state load measurement, which is especially significant for
single-acting actuators since you can use it estimate the actuator spring force and spring
condition.
The calculation is based on the pneumatic pressure measurement that is carried out
whenever the valve is in a steady state. The current value is compare with the value recorded
during calibration.
If the spring is broken, Stable State Load decreases noticeably.
Threshold Limit 1
This parameter defines the magnitude of the permissible pressure difference from the
recorded value.
•
