PURPOSE AND SCOPE OF APPLICATION

Explosion-proof digital LED display PGS-BS is applied at chemical, oil-and-gas producing, oil-and-gas-processing and shipbuilding facilities, and in hazardous areas at other production facilities and enables indication of any information (time, temperature, emergency exits, advertising and trade, technical information etc.) in places where explosive atmospheres may be present.

The advantage of this solution is a possibility to programme any text or graphic directly on customer‘s site (programming interface RS232), and high legibility of displayed information thanks to light emitting diodes of high brightness.

Explosion-proof digital LED display PGS-BS ensures possibility of text display with effects: static sign, twinkling sign, scrolling sign). The advantage of a scrolling sign is a possibility to display a large amount of text and graphical information on a relatively small area of the display, by means of horizontal move of displayed information. Data unit is uploaded to the memory of the explosion-proof digital informational display and after that the display operates independently (i.e. constant connection of RS232 is not required). Explosion-proof digital LED display is equipped with non-volatile memory which ensures storage of uploaded information independently from presence of power supply.

As of today, explosion-proof display PGS-BS is the biggest pf its kind. It comprises all advantages of LED displays and has the dimensions of display area 960x160 mm and resolution 16 dots in vertical direction, and that allows display of information in bolded fonts, which improves its comprehension by people with vision disorders from all viewing angles and gives competitive advantage over analogous products of other manufacturers. Radiant intensity and brightness of light emitting diodes of text output of red or green color on black background completely ensures contrast perception of information in any lighting conditions.

Size of display area of LED board is 960x160 mm, 640x160 mm and 320x160 mm. Image resolution can be 32х16, 64х16, 96х16 dots. Indication color: single-color - red, white, yellow, green, blue; two-color - red/green.

Stainless steel enclosure guarantees reliability and durability of operation of the explosion-proof display even in the harshest operating conditions.

Scope of application - hazardous indoor and outdoor areas in accordance with explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) that regulates application of electrical equipment in hazardous areas, dangerous production facilities of I, II, III, IV hazard classes under supervision of Rostekhnadzor and national supervisory bodies of the CU and the CIS countries.
