Digital panel meters are electronic devices that display electrical parameters in digital format. The digital panel shows numeric readings of a specific electrical parameter. Digital meters have higher accuracy and precision and hence find an array of electrical applications.
They are widely used for industrial and commercial purposes because of their cutting-edge technology, top-notch features and ease of use.
This blog will throw light on important features of digital panel meters, their method of operation, types of digital panel meters and their applications.
Components of Digital Panel Meters
The display of Digital panel meters gives numeric readings and includes indicators and symbols for alarms and units.
2. Microcontroller or Digital Signal Processor (DSP)
This is like the brain of the digital panel meter. It processes the measured data, performs calculations, handles user interface interactions, and controls various functions of the meter.
3. User Interface
Digital panel meters include buttons, switches, or touch-sensitive controls for user interaction. These allow users to access menu options, set configurations, navigate through different displays or modes, and configure alarms or data logging functions.
4. Power Supply
Digital panel meters require a stable power supply, typically in the form of AC (Alternating Current) or DC (Direct Current) voltage, to operate.
Method of Operation Of BEEMET Digital Panel Meters
BEEMET Digital Panel meters utilize Dual Slope A/D conversion for analog-to-digital signal conversion. In this method, the analog signal is integrated with a known reference voltage for a fixed period. After nullifying any system offsets, the unknown signal is integrated for the same duration. The integrated value is then compared with a digital reference, adjusting it until a match is achieved. This process determines the digital output code representing the input signal. Dual Slope A/D conversion ensures accurate and reliable measurement, offering benefits such as noise rejection and insensitivity to reference voltage variations.
Types of Digital Panel Meters
Mainly, there are two types of panel meters named single-function panel meters and multifunction panel meters.
Single Function Digital Panel Meters
These panel meters display only a specific parameter like current, voltage or power.
