Volume II: Actuation, Maintenance, and Safety Relief, takes an in-depth look at actuators and positioners. This volume also explores a variety of maintenance and diagnostic issues including: testing for dead-band/hysteresis, stick-slip and non-linearity; on-line diagnostics; signature analysis; and correct procedures for calculating the spring "wind-up" or "bench set." A complete section is also devoted to the whole field of safety relief devices. Lastly, this volume covers a number of topics which are all too often ignored: acoustics; water hammer; and even classification of stainless steel.
