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 choose a right digital panel meter?
First of all, you need to decide the function of the digital panel meter you want, and then choose according to your needs.
The basic function of all digital panel meters is to convert an input signal into a displayed value. The control panel provides power to the device and inputs required for the meter display. Inputs come from sensors in the system or process and are sent to the device through the panel to which the meter is connected. Some digital panel meters may also have optional control or interface functions: the analog function can provide an analog output proportional to the input signal (such as a variable voltage or current) for use with analog devices. The data interface function allows interaction with displayed output information for analytical use.
