Digital indicators with bar charts are used in radios and tapes to adjust the sound. These digital displays with bar graph have been used in electronics for a long time. Peak values that occur for short periods are represented safely by bar graphs. Another advantage of digital indicators with bar charts is that the signal changes are identified before the 7-segment digital displays. A big advantage is that this system allows you to measure directly the changes in values.
The user can easily see on the digital indicators bar charts the behavior of measurement values.
A good example of this is to control temperature and humidity. Digital indicators with bar graphs of two channels are used to control two magnitude processes. Digital indicators with bar charts show the measurements of the signals in a light bar, such as changes in resistance or standard signals. Thus, digital indicators with bar charts can change color on the top of the bar, which tells the user that a fault is detected, or that a certain threshold is passed. Alarm limits can be visible on the screen. Digital indicators with bar charts allow to visualize processes quickly, changes in the signal and peak values, which facilitates the process. Therefore, the length of the illuminated bar graph provides information on the magnitude. On digital indicators with bar charts LEDs analogue signal is visible. The upper bar of the bar graph digital indicators can change its color indicating that a fail is detected or the limit value is exceeded. Bar graph digital indicators display processes, changes in the signal and peak values which facilitate the process. (two-channels bar graph with universal input, dual 7-segment display)īar graph digital indicators show an analogue signal by LEDs, so the illuminated bar graph length provides information about the magnitude.

All settings made in the bar graph digital indicators can be secured by a PIN code to avoid unauthorized personnel change of the parameters. Bar graph digital indicators can also process voltages up to 600 V. Bar graph digital indicators can process, apart from normalized signals, thermo elements and resistance thermometers.
Digital indicators are available with one or two channels to show, for instance, temperature and relative humidity. This fact allows connection with other alarms, for instance an acoustic and visual alarm siren. Bar graph digital indicators have different relays to a parallel switch of the diverse default alarm limits. For instance, the LED display of the bar graph digital indicators can be programmed to become red when a certain level is reached.
The image of the bar graph with multicolor LED display can be changed through the different alarm limits. Users can set their own parameters in the bar graph digital indicators. Bar graph digital indicators normally receive a 4-20 mA signal. Bar graph digital indicators are used in those places where it is necessary to check the level of a process as for instance, in the industry to check the level in silos and stock piles.
