Instrumentation for Process Control

A Resource of Value for Industrial Engineering. Here is an Online Textbook for learning advanced process control concepts. The Process Control Education Web Site Industrial Automation enables Higher skill levels for workers and reduces danger of accidents too. Now the emphasis is for Energy Efficient Industrial Production, not only to save Energy Costs but as a Social Responsibility. Industries should not pollute water bodies and the atmosphere, this brings us to new process control area of Air and Water Quality Measurement and regulation. The Reference includes Sample Process Control Course, Instrumentation for Process Control, WEB-Based Educational Resources for Process Control [Read More ....]

Process Control Instrumentation - McShane

New serial interface RS-422 improved upon RS-232 serial communications which was Noise prone. RS-422 uses two signal lines. RS-485 enhances RS-422 with an ability to connect upto 32 devices. Now we have Industrial Interface methods like Zigbee, Ethernet, Modbus etc. RS-485 Serial Interface – McShane, Inc. Temperature Controller for DC Load and TEC Model 5C7-582 or Model 5C7-583 temperature controllers provide automatic biphase heating and cooling control for Thermoelectric (Peltier effect, or TEC) modules. More about the Company Founded by Philip Johnson in 1964, McShane, Inc. supplies process control equipment, OEM devices, and industry services from our location south of [Read More ....]

A Closed loop control system has a Sensor-Controller-Actuator. The Bimetal Thermostat has all the three in the Bimetal itself. The Sensor, the Relay Contact and the Intelligence. This is Process Control when implemented to control the temperature in a Bakery Oven. This leads us to Sensors-Transmitter-Controller-Outputs-Actuators. Where each is an independent electronic/electrical component of an entire Process Control system. The Process could be Temperature, Pressure, Speed, or Level. Industrial Automation encompasses many such Process Control Systems to form a Engineered System Solution for an Entire production line with different stages and process types. At the machine end, the control has [Read More ....]

Training Demo jig panel set that uses the DCS process management package, DeltaV of Emerson. Complete Distributed Process Control System Process Control : Educational Equipment Here you can see a scaled down version of the real thing, these are ways Paper, Oil and some Materials are processed in Big Factories. Study the control of processes like Level, Flow, Temperature, Pressure and the needed Actuators used to monitor and manage a stable multi-loop system. Process Automation is needed to ensure quality of the output and safety of plant and environment. The most important thing is to make it energy efficient.

I just got a letter from a US firm enquiringly about my transmitters. It read something like … “…..Mini RTD Pt100 Three Wire Transmitter is commercially available? We may be interested in both the 100 ohm RTD input as well as the 1K ohm RTD input types” I do not respond to product enquiries as i do not “Make” anymore. But, this letter is about a design of mine that is published in my pages. It is a low cost transmitter anybody can build. Study my Elex Quna where some such letters are published. I may now reply only mail [Read More ....]

Temperature and Pressure Controllers form a large part of Process control Instrumentation. Then you have Flow, Humidity and many more custom parameters. 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. These Analog Values go to Analog Closed Loop Controllers or Meters for Measurement and Control. In Embedded Controllers, the Analog is converted to Digital ( At least 12 bit, 8 bits are cheap not used for industrial automation, more than 16 bits is not required [Read More ....]

Proportional Module for Process Controller

 Process Control  Comments Off
Mar 232009
 

When you need a proportional control output, either 4-20mA or Time Proportional On-Off, This module is used. It does a slow PWM control, the cycle time for SSR or Thyristor Banks can be closer to Mains Frequency. The 4-20mA can be used to drive motors for turning valves for fuel or fluid heat control. Schematics of Module Proportional Control Card Two Set Point Card Proportional Control Card 4-20 mA Board of Module Proportional Module Copper Proportional Module Solder Mask Proportional Module Silk Screen Proportional Module Drill Template
