These pages of mine and other sections of delabs lists firms and EE design resources around the globe, related to Professional and Hobby Electronics. This work of mine started in 1999 on netscape, geocities and tripod homepages. Now it is distributed over few domains and tech blogs that i own and manage.

Instruction Manuals of Process Control Instruments and Industrial Automation Solutions, Control Panel Diagrams, Wiring, and Facia.

Temperature and Pressure Controllers form a large part of Process control Instrumentation. Then you have Flow, Humidity and many more custom parameters.

Electronics Theory - Industrial Control Panels

All Real Life Physical Phenomena are reduced to Analog Numbers by Sensors and Transducers. This analog value is amplified and linearized and brought into standardized windows like 1-5 Volts or 4-20mA and more.

The very first designs that came about were analog designs, a Vacuum Tube amplifier is an example. Analog is the representation of data or physical parameter in an accurate and precise decimal number like + 72.182 mV. The greater the resolution required, the more demanding is the design for achieving high accuracy and low drift. Digital circuits have only two voltage levels, high and low, the third state of floating, Hi-Z or high impedance is only for multiplexing or sharing a bus. This is done so that devices dont drive into each other and it is also used in external port drivers.

Analog Design and Circuits

As an analogy, see the conventional water tap as an analog control, an electric light ON-OFF switch as a digital control.

A computer can be used to control or automate systems. From turning lights on/off at your home to shutting down motors or heaters in industries. Speed control and PID Control too.

Control Interface to PC Ports.

PC based Instrumentation is easy to implement using USB Devices and Plugin Cards for Test and Measurement.  Most instruments can communicate with PC on the GPIB interface.
