AMMETER (EDM – 80) SQUARE Dial
Range 0-15 and 0-25 Amp
An ammeter, also known as an amperemeter, is an essential electrical instrument used to measure the electric current flowing through a circuit. It is widely employed by electrical engineers, technicians, and scientists to monitor and analyze current levels in various applications.

The ammeter operates on the principle of electromagnetic induction. It consists of a calibrated coil, often referred to as a shunt, that is connected in series with the circuit under measurement. As current flows through the circuit, a magnetic field is generated, resulting in a force on the shunt coil. This force deflects an indicating needle or displays a digital readout, providing a direct measurement of the current passing through the circuit.

Ammeters are designed to be highly accurate and sensitive, enabling precise current measurements across a wide range of values. They are available in different types, including analog and digital models, each offering specific advantages depending on the application.

Analog ammeters feature a mechanical movement mechanism, where a needle traverses a calibrated scale to indicate the current value. These instruments offer a visual representation of the current and are still widely used due to their simplicity and immediate readability. Analog ammeters are available in various sizes and ranges to accommodate different current levels, ensuring accurate readings for both small and large currents.

Digital ammeters, on the other hand, employ digital technology to provide numerical readings of the current. These instruments utilize digital displays, such as LCD or LED screens, to present precise measurements. Digital ammeters often offer additional features such as auto-ranging, data logging, and communication interfaces, allowing for more advanced data analysis and integration into automated systems.

Ammeters are designed with safety and usability in mind. Many models incorporate protective measures, such as internal fuses or current-limiting devices, to prevent damage from excessive current. Additionally, they often feature clear and intuitive interfaces, allowing for easy operation and interpretation of results.

Ammeters find extensive use in various industries and applications. In the field of electrical engineering, ammeters are employed in circuit testing, troubleshooting, and system maintenance. They are crucial for verifying current flow in electrical installations, identifying faulty components, and ensuring proper functioning of electrical systems.

In scientific research and development, ammeters play a vital role in conducting experiments, analyzing electrical phenomena, and characterizing electronic devices. Their high accuracy and sensitivity enable precise measurements required in fields such as electronics, power systems, and materials science.

Furthermore, ammeters are widely utilized in industrial settings for quality control and production processes. They ensure that machinery and equipment are operating within the desired current limits, facilitating efficient and safe production.

In summary, the ammeter is an indispensable instrument for measuring electric current accurately. With their reliable and sensitive performance, ammeters allow for the monitoring, analysis, and control of current in a wide range of applications. Whether in analog or digital form, these instruments enable professionals to ensure the optimal performance, safety, and efficiency of electrical systems and devices.
