noun
differential gap
Technical term in control engineering: the dead zone or hysteresis gap between the on and off switching points of a controller, preventing rapid cycling.
サーモスタットの動作隙間を調整して、頻繁なオンオフを防ぐ。
Adjust the thermostat's differential gap to prevent frequent on-off cycling.
この制御装置は動作隙間が狭すぎると、チャタリングを起こすことがある。
If the differential gap of this controller is too narrow, it may cause chattering.
Hysteresis is a broader physical phenomenon; 動作隙間 specifically refers to the intentional dead band in a switching controller.
不感帯 (dead zone) is a more general term for an unresponsive range; 動作隙間 is often used synonymously in control contexts but emphasizes the gap between switching actions.
Compound of 動作 (operation, action) and 隙間 (gap, clearance), literally 'operation gap'. The term is a technical calque from English 'differential gap' used in control engineering.
