# classify-transducer

`station__power-systems__classify-transducer` · external (needs EXECUTION_BACKEND_URL configured) · domain `power-systems` · pv-relevance `non-pv`

Classify a physical transducer by energy domain mapping (mechanical/thermal/optical/chemical/electromagnetic/acoustic/nuclear → electrical/mechanical/thermal/optical/acoustic). Returns transducer class, device examples, primitive formula, efficiency range, and conservation note. 17 classes covered.

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.
