During a recent machinery protection overhaul at a high-load petrochemical plant, our technical team evaluated signal linearity across varying fluid-film temperatures. We verified that maintaining stable -17.5 Vdc to -26 Vdc power supply inputs completely eliminates thermal scale factor drift, ensuring true 200 mV\/mil output scaling through extended operational lifecycles.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eConfiguration Breakdown \u0026amp;
