Advanced Methods for Tuning a PID Loop A PID loop adjusts its OP to maintain its PV at its SP. Some PID loops cannot be satisfactorily tuned by adjusting the three primary constants. When combined with good basic tuning, advanced methods can improve stability, responsiveness, and limit overshooting. See The Basics of Tuning PID Loops for …

How to Tune a PID Loop The art of tuning a PID loop is to have it adjust its output (OP) to move the process variable (PV) as quickly as possible to the set point  (responsive), minimize overshoot, and then hold the variable steady at the set point without excessive OP changes (stable). Definitions PID = …

Hazardous Area Classification Guide The National Electrical Code (NEC) defines hazardous locations as those areas “where fire or explosion hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust, or ignitable fibers or flyings.” Hazardous locations are classified in three ways by the NEC: type, condition, and nature. Hazardous Location Types – …

Square Root Scaling for Differential Pressure (DP) Flow Meters Instruments should be ranged to measure not only expected values but all values the system can produce. During upsets, actual values often exceed 20mA values for instruments tightly ranged for normal process conditions. For instruments with linear scale and additional capacity, the fix is simple: increase …
