Quantitative PID tuning procedures
A quantitative PID tuning procedure is a step-by-step approach leading directly to a set of numerical values to be used in a PID controller. These procedures may be split into…
How ANSI Class Relates to PSI ?
Take a look through our website and you’ll see most of our pressure ratings are expressed as PSI - pounds per square inch. In this article, we’d like to talk…
NPT Connection Measurement Size
A 1/4” NPT connection size doesn’t have the 1/4” measurements where you think they would be. In fact, the connection’s outside diameter measures a little more than 1/2" wide. Did…
What is a Y Strainer ?
Y-strainers find their ways into all kinds of applications – including food preparation, cosmetics, diesel engines, and the petroleum industry. Y Strainer : Y-Strainers can be installed horizontally or vertically with…
AC Motor Speed Control
AC induction motors are based on the principle of a rotating magnetic field produced by a set of stationary windings (called stator windings) energized by AC power of different phases.…
DC Motor Speed Control
DC electric motors generate torque by a reaction between two magnetic fields: one field established by stationary “field” windings (coils), and the other by windings in the rotating armature. Some…
Industrial Instrumentation Questions & Answers
Industrial Instrumentation Questions & Answers Measurement of Force, Torque & Speed What is a Stroboscope ? The stroboscope is a simple, portable manually operated device which may be used for…
What we need to Know before Tune a PID Controller ?
We know the benefits of robust PID control Tuning. Increased productivity, decreased equipment strain, and increased process safety are some of the advantages touted of proper PID tuning. What is…
Steady-State Process Gain
When we speak of a controller’s gain, we refer to the aggressiveness of its proportional control action: the ratio of output change to input change. However, we may go a…
Optical Flow Meter Principle
A recent development in industrial flow measurement is Optical Flow Meter which uses light to measure the velocity of a fluid through a pipe.
