Common
Study the common instrumentation and control engineering topics to upgrade your knowledge in industrial control systems and field instruments.
Pressure Regulator with Flapper-Nozzle Principle
Pressure Regulator with Flapper-Nozzle is nothing but a I/P converter. Flapper-nozzle principle: The electromagnetic field changes the space between flapper
Hysteresis
A detrimental effect to feedback control is a characteristic known as hysteresis: a lack of responsiveness to a change in
Dead time
Lag time refers to a damped response from a process, from a change in manipulated variable (e.g. control valve position)
Multiple Lags (orders)
Simple, self-regulating processes tend to be first-order: that is, they have only one mechanism of lag. More complicated processes often
Lag time
If a square-wave signal is applied to an RC passive integrator circuit, the output signal will appear to have a
Electrical Switches Principle & Types
Electrical Switches have mechanical contacts or relays. Types of electrical switches are SPST, SPDT, DPST, DPDT and other custom designs.

What is a Load Cell ?
A load cell or loadcell is a highly accurate device that is used to measure weight or force in a
Importance of Device Diagnostics
Device diagnostics can be carried out using a handheld communicator in the field, a laptop in the workshop, or from
