Bar Graph Digital Indicators
Bar graph digital indicators are used in those places where it is necessary to check the level of a Professional Bar Graph Digital Indicators for the control and inspection process as for instance, in the industry to check the level in silos and stock piles. Bar graph digital indicators normally receive a 4-20 mA signal. Users can set their own parameters in the bar graph digital indicators. The image of the bar graph with multicolor LED display can be changed through the different 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. Bar graph digital indicators have different relays to a parallel switch of the diverse default alarm limits. This fact allows connection with other alarms, for instance an acoustic and visual alarm siren. Digital indicators are available with one or two channels to show, for instance, temperature and relative humidity. Bar graph digital indicators can process, apart from normalized signals, thermo elements and resistance thermometers. Bar graph digital indicators can also process voltages up to 600 V. All settings made in the bar graph digital indicators can be secured by a PIN code to avoid unauthorized personnel change of the parameters. If you have any questions regarding our bar graph digital indicators, contact us: +44 ( 0 ) 2380 98703 0 and our technical staff will be happy to help you find the bar graph digital indicators that best suit your needs as well as advise you on the rest of our measuring instruments and scales.

Bar graph digital indicators show an analogue signal by LEDs, Bar Graph Digital Indicators performing a measurement.so the illuminated bar graph length provides information about the magnitude. Bar graph digital indicators display processes, changes in the signal and peak values which facilitate the process. Alarm limits can also be displayed. 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. On digital indicators with bar charts LEDs analogue signal is visible. Therefore, the length of the illuminated bar graph provides information on the magnitude. Digital indicators with bar charts allow to visualize processes quickly, changes in the signal and peak values, which facilitates the process. Alarm limits can be visible on the screen. 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. Digital indicators with bar charts show the measurements of the signals in a light bar, such as changes in resistance or standard signals. Digital indicators with bar graphs of two channels are used to control two magnitude processes. A good example of this is to control temperature and humidity. 

Bar Graph Digital Indicators show an analogue signal by LEDs.

The user can easily see on the digital indicators bar charts the behavior of measurement values. A big advantage is that this system allows you to measure directly the changes in values. Another advantage of digital indicators with bar charts is that the signal changes are identified before the 7-segment digital displays. Peak values that occur for short periods are represented safely by bar graphs. These digital displays with bar graph have been used in electronics for a long time. Digital indicators with bar charts are used in radios and tapes to adjust the sound. Today we continue to use digital displays with bar graph in audio mixers because it lets the user know that a certain level of sound is reached. In the computer industry, digital displays with bar graphs are considered to be comfortable units that give the user quick information about a certain state. Therefore, programmers in the installation process install digital displays with bar graphs showing the installation progress.
