Q1: What is a digital panel meter?
A1: The digital panel meter displays the voltage, current value or other standard signal transmission display value in the electrical circuit by digital direct reading; the product has the advantages of good stability, strong anti-interference, high cost performance, and the product is small in size and can be directly replaced original pointer meter.
Q2: What are the functions of digital panel meters?
A2: Digital panel meters can be categorized by type, size, style or other criteria. Understanding the functions of the digital panel meter is an important factor in choosing it. Commonly used functions are ammeters, voltmeters, frequency meters, power meters, energy meters, counters, timers, thermometers, process meters and controllers.
Q3: What are the advantages of digital panel meters?
A3: The digital panel meter directly displays the measured value or deviation value by digital quantity, which is clear and intuitive, easy to read, and will not produce parallax. Digital panel meters generally use large and medium-scale integrated circuits, with simple circuits, good reliability and good shock resistance. Because of the common modular design method for instruments, that is, digital panel meters are mostly composed of a small number of modular circuits with separated functions, so they are conducive to manufacturing, debugging and maintenance.
Tips: Why use a digital panel meter?
Digital panel meter is an electronic device that converts signals such as load cells or weight transmitters into digital display of weight, which can store, count and print weight data. It is often used in automatic batching and weighing in industrial and agricultural production to improve production efficiency.
With the development of technology, the digital panel instrument manufacturing industry has introduced microelectronics technology, which greatly improves the predictability and accuracy of the display controller and improves its reliability.
Before use, the digital panel meter should be calibrated with a load cell. Calibration is the calibration of the display controller with standard weights. The calibration coefficients relative to this set of sensors are stored in the calibration instrument. With these coefficients, the panel meter can convert the load cell's analog signal into a digital weight display.
