A Digital Panel Meter (DPM) is an electronic instrument whose core function is to convert input electrical signals into intuitive digital readings displayed on LCD or LED screens. Its working principle is based on analog-to-digital conversion (ADC) technology: the input analog voltage or current signal is first conditioned (scaled and filtered), then the analog-to-digital converter converts the continuous analog quantity into a discrete digital value, which is finally processed by a microcontroller and displayed as a clear, easy-to-read numerical value.
Product Features
1. High Precision and Readability: Provides accurate measurement results, with digital display completely eliminating the parallax errors associated with pointer meters.
2. Strong Versatility and Programmability: Modern digital panel meters support programmable settings for multiple input ranges (e.g., 0-10V/4-20mA) and can be configured to display engineering units (e.g., ℃/psi/rpm), meeting the needs of various sensors.
3. Compact Structure and Easy Integration: Designed specifically for panel mounting, they occupy minimal space, feature simple wiring, and can be quickly integrated into systems such as control cabinets and mechanical equipment.
Common Applications
1. Industrial Process Control: Displaying process parameters such as temperature, pressure, and flow rate on control panels.
2. Power Supplies and Controllers: Real-time display of output voltage, current, and power values.
3. Test and Measurement Systems: Serving as standard display units for various electronic test platforms and data acquisition systems.
