Analog panel meters are devices that display measurements of electrical parameters using a dial and a moving pointer. They have been widely used for decades and continue to be an essential tool in various industries. Whether you’re a beginner or looking to expand your knowledge, this blog will provide valuable insights into the operation, types, advantages, and applications of analog panel meters.

Components of Analog Panel Meters

Dial & Scale of a Analog Panel meter
1. Dial & Scale

The dial is the face of the meter with numbers and markings that show the measurements. The scale helps you read the values correctly.

2. Pointer

The pointer is the moving part that shows the measurement on the dial. It moves along the scale to indicate the value of the parameter being measured.

3. Movement

The movement is the mechanism inside the meter that connects to the pointer. It responds to the electrical signals and makes the pointer move accordingly.

4. Magnets

Magnets create a magnetic field that interacts with the electrical signals in the meter. This causes the pointer to move and shows the measurement on the dial.

Frame provides a protective casing for the internal components of the meter. It keeps the meter sturdy and safe from damage.

Operating Principle of Analog Panel Meters

Analog meters operate based on the electromagnetic induction principle.

1. Moving Coil Principle

Moving coil is the current-carrying coil placed in the meter. The coil is suspended in a magnetic field generated by permanent magnets or electromagnets. When an electric current flows through the coil, it creates a magnetic field around it. The interaction between the magnetic field of the coil and the magnetic field of the meter causes the coil to rotate.

2. Force on the Moving Element

When the magnetic field is created, the moving coil moves in response to it. As it moves, it experiences a force. This force deflects the pointer attached to the moving element. The deflection of the pointer indicates the value of the measured parameter on the meter's scale.

3. Measurement Scale

The meter's scale is calibrated to provide accurate readings for the measured parameter. As the pointer moves along the scale, it aligns with the corresponding value of the measured parameter.

By utilizing these principles of electromagnetic induction, analog meters can measure electrical parameters and display them on meter’s dial.

Types of Analog Panel Meters

Here are some common types of analog panel meters designs for different parameters:

1. Ammeters

Measure the flow of current in Amperes in electrical circuits.

2. Voltmeters

Measure electrical potential difference in the circuit in volts (V).

3. Ohmmeters

Measure electrical resistance in ohms (Ω). Ohmmeters are used to test the resistance of components or circuits.

4. Frequency Meters

Frequenncy of an electrical signal is measured in Hertz.

5. Pressure Meters

Measure fluid or gas pressure. Pressure meters are utilized in various industries for monitoring and controlling pressure levels.

6. Level Meters

Measure the level of liquids or solids in tanks or containers. They find application in industries such as water treatment, agriculture, and manufacturing.

7. Wattmeters

Wattmeters monitor power consumption in electrical systems. They are measured in watts.

8. RPM Meters

Measure the rotational speed of machinery or motors. RPM meters are commonly used in automotive, industrial, and mechanical applications.

Difference Between Analog & Digital Panel meters

1. Display

A dial and point is used to indicate measurements on the scale in analog meters while digital panel meters use a digital display to indicate measurements.

2. Readability

In analog meters, you have to interpret the position of a moving pointer to get a proper reading. This is not the case with digital meters as they offer precise numerical readings and eliminate interpretation errors.

3. Accuracy

Analog Panel Meters have lower precision and accuracy compared to digital meters.

4. Additional Features

Analog meters do not provide any other feature apart from basic measurement. Digital panel meters offer advanced features like data logging, alarm communication interface and more.

Bottom Line

Analog meters offer simplicity, real-time response, and a direct visual interpretation of measurements. Despite the digital advancements, their durability, wide measurement range, and timeless charm make them valuable tools in various applications Explore a range of analog panel meters by BEEMET.
