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: How to determine whether the measurement of the 5 digit display controller is correct?
Connect a few load cells to the display controller. One person stands beside several load cells and checks whether the value of the weight controller is the same. This method is very simple and effective. If the data displayed by each sensor is different, there is a difference in angle. At this time, the height of each sensor should be adjusted to eliminate angle differences. If there is no angle difference, but the data is not correct, it needs to be recalibrated.
