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 suggestions on…

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 = Proportional,…

Did you know... the precision measurement group at Cross was founded in 1939 by our current CEO's grandfather, Jim King. That's a whole lot of calibration!
Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet to paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are a 100% employee owned! Learn more about our ESOP and how that benefits both team members and our customers.
