Generators are devices that convert mechanical energy into electrical energy. Generally, the source of mechanical energy ranges from an internal combustion engine to a hand crank to compressed air or a reciprocating steam engine. An internal combustion engine uses fuels such as diesel, gasoline, propane gas, or natural gas to produce mechanical energy, which is converted into electric energy with the help of the generator assembly. These generators generally serve as backup power in residential, commercial, and industrial applications. A fuel engine powers a typical generator.

Generators are devices that convert mechanical energy into electrical energy. An internal combustion engine makes use of either diesel, gasoline, propane gas, or natural gas to produce mechanical energy, which is then converted into electrical energy with the help of a generator assembly. Because generators are designed to provide temporary AC or DC power, they serve as sources of backup or emergency power for use in residential, commercial, and industrial applications. A fuel engine powers a conventional generator.

Process automation and instrumentation is a necessity for industrial manufacturing, as it helps in optimizing business outcomes. It aids in effectively controlling and monitoring the industrial production process by minimizing downtimes of a plant. The global process automation and instrumentation market has a significant growth potential from the developing countries such as China, India, Indonesia, Brazil, Argentina, and Mexico. The increase in business competition among competitive organizations and companies has led to growth in the global process automation and instrumentation market. The need to control and monitor processes has led to the growth of the global process automation and instrumentation market with advanced automation products and solutions.

A signal generator is an electronic device used to generate waveform and electronic signals. The electronic signals are either repeating or non-repeating signals, in any of the two domains, namely analog and digital, depending on the requirements and applications for which they are used. These are used to repair electronic devices as well as for troubleshooting, designing, and testing. The signal generators are classified according to their parameters, designs, and dimensions.
