Inserting Alarm System to an Oil Pump Control Circuit

At some point in time, you may happen to have an old industrial pump unit wired inside an existing control panel that would require circuit modification in order to include an alarm system. What is being referred to here are pump systems most commonly found in industrial facilities such as oil pump, hydraulic pump, grease pump, water pump, air pump or air compressors, but nevertheless, the electrical circuit presented in this article may also be used to set an example to provide idea for other similar applications.

In heavy industrial facilities, one of the important foundation of a good working machinery is dependent on the condition of a well-oiled mechanism. This pertains to having a reliable lubrication system that ensures all moving parts of every machinery in the factory are well-lubricated in order to diminish friction and grinding on the machine's mechanical joints and contacts.

Electrical Circuit for Controlling a Lifting Electromagnet for Overhead Cranes with Top Running Trolley Hoist

When the need to conveniently pick up and lift heavy iron or steel objects for transferring from one place to another was seen as a necessity in heavy industrial facilities, the concept of using an electromagnet was implemented due to its ability to be turned ON and OFF which was then incorporated effectively to the hoist function of overhead cranes.

Overhead-travelling-crane magnets are electromagnetic device attached to the crane's hook to magnetically pick up heavy metallic loads for hoisting and transferring.  Cranes that are fitted with a lifting magnet are equipped with an electromagnet control circuit.

Wiring Connection for a Three Wire Solid State DC Proximity Sensor Without PLC

The previous article illustrated the concept of the wiring connection of a 3 wire DC proximity sensor to a PLC (Programmable Logic Controller). Alternatively, in this article, I will explain another approach on the wiring connection of the same proximity sensor but without using a PLC.

How to Connect a 3 Wire DC Solid State Proximity Sensor to a PLC

Knowing how to connect a 3 wire DC solid state proximity sensor to a PLC (Programmable Logic Controller) is dependent on the type of proximity sensor and the PLC to be used that is specific to the design of the circuit and the preferred application.

Pinch Roller Automatic Grip Control After Shear Cut Using PLC Program

What is a pinch roller? A pinch roller is a rotating machine consisting mainly of two rollers arranged in parallel either horizontally or vertically depending on the process required to pull the material that is rolled in the mill. These two rollers are coupled to a variable speed electric motor which is constantly rotating at a preset speed that is synchronized with the speed of the preceding finishing roller located before the pinch roller.

Types of electrical circuit connections - Basic tutorial on series and parallel circuit

There are mainly two basic types of circuit connection in an electrical system. These two basic configuration are most commonly known as the series connection and the parallel connection.

Although there are a lot of other complex circuits constructed from various designs and installation purposes to suit specific electrical requirements, all of them are based from a combination of these two basic wiring principle.

Learn how to use an electrical multimeter - A basic introduction tutorial and multimeter manual

Introduction:

When you get behind the wheel of a car, what is the next thing that you would most certainly do besides closing the door and strapping yourself securely to the seat. Obviously enough, it is expected that you would turn the ignition to start the engine, grab the steering wheel, shift the gear and step on the pedal because this is the most basic routine that every driver would instinctively do to drive a car. This inherent trait almost comes as a second nature to all experienced driver, which simply is an automatic pattern of behavior in reaction to the specific situation of driving a motor vehicle.

Similarly, having an aptitude for using an electrical multimeter would always come in handy when working with electrical circuits. Just as it is vitally important to have a thorough understanding about what makes up the structure of an electrical circuit, which involves the installed electrical switching components that are connected in such a way as to provide a continuous controlled flow of electrical path between the circuit's supply or source voltage down to the connected load in the circuit, so too is the importance of using a multimeter in circuit analysis.
