Without a display, the measurement results determined by sensors are invisible. Digital displays, technically also referred to as process displays, make visible the information transmitted to them in the form of numbers, characters and/or letters.
In contrast to many other forms of display, powerful displays with fast response times and self-illumination are easy to read even in poor lighting conditions and from a great distance. This also applies to our universal process displays, whose 17 mm high displays offer a clear view and thus make them easier for operators to read.

The most commonly used type of digital display is the seven-segment display, which is also used in digital watches and pocket calculators. This can display the digits from 0 to 9, plus a large number of letters, with the help of up to seven individual lines. Compared to normal fonts, the representation is abstract, so not quite perfect. This is particularly evident with the digits 4 and 7. In daily life, however, this is hardly noticeable due to the widespread use of seven-segment displays, which people have become used to.
Since the vast majority of systems today use data width of at least 8 bits, most display elements have a point as the eighth “element”. This is usually located on the baseline to the right of the lowest segment. It is controlled via the eighth data bit and is primarily used as a decimal separator. Specialized digital displays for the visualization of temperatures also have a degree symbol in front of the last display element, which is used to display the unit (C for Celsius or F for Fahrenheit).
Today, the segments on most digital displays are made up of light emitting diodes (LEDs) or liquid crystal displays (LCDs). They are controlled via integrated seven-segment decoder circuits (ICs) that convert binary-coded numbers (4 bits) into 7 bits to control the seven segments. In the meantime, programmable microcontrollers are partially replacing the ICs in smaller displays. To do this, however, it is necessary to reduce the number of necessary I/O connections on the microcontroller with a BCD-to-7-segment decoder.
Our universal process indicator is a seven-segment display. With six digits for high-resolution variables and a 17 mm high display, it offers everything required to display measured values in industrial environments. It works with a fast sampling rate and ensures powerful visualization and response. This makes it ideal for use in areas with high process dynamics.
The timer function on our digital displays offers a wide range of possible actions, such as alarms for safety interlocking. With linearized inputs for up to 30 points, the displays are also fully compatible with customer-specific signals and sensors from other manufacturers. Both their non-flammable housing and electronic robustness meet all the requirements of the most important world-class approvals for use in the industrial sector.
