Control and Automation Technology
By Dave Rongey
Summary: How Frequencies are Used to Monitor and Control Equipment for Electrical Automation.
Devices for Automation and Remote Control
Frequencies play an important part by providing the link between a personal device, such as a cell phone, and a network of other cell phone users and the wide range of services provided through a common telephone connection that is part of the internet.
As important as cell phone conversations may be, so too are the many connections that keep the Internet functioning while routing millions of packets of information at an ever increasing rate of speed.
How Electrical Systems are Used to Monitor and Control Equipment
Just as cell phones are used to connect people with one another using voice conversations or text messages, the same communication technology is used to connect vast amounts of equipment to one another or large networks which then provide reports about how equipment is performing and control set points which may activate a variety of control operations.Control Systems
Specific control networks are set up providing communications with digital and analog devices for the purpose of monitoring and controlling equipment at a local business, such as a large supermarket, or a more complex facility such as a hospital. These data acquisition networks, also known as SCADA systems, monitor temperatures of equipment or areas, and then software instructions make programmed decisions to turn equipment on or off.
The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..
The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
