Control Loop Signal Package

Calculates source-bound control-loop metrics from a deterministic SSC-18 task-owned source pack. The template combines valve pressure drop and Cv sizing, linear 4-20 mA signal scaling, alarm and trip current conversion, and control-loop headroom checks for a compact generated task instance.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

easy:: All source-pack values given for the SSC-18 control-loop signal package
medium:: All source-pack values given for the SSC-18 control-loop signal package
hard:: All source-pack values given for the SSC-18 control-loop signal package
