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 set digital panel meter?
The parameters of the digital panel meter generally include the upper limit of the measurement value, the lower limit of the measurement value, the upper limit of the deviation, the lower limit of the deviation, and the absolute value of the deviation. For example, the upper (lower) limit of the measured value is used to set the maximum (minimum) measurement range of the displacement. Used to display the displacement value sent to the DCS control system.
