Explosion-proof equipment plant
Explosion-proof motion sensors DVG-SHAG are intended for automatic load switching on and off in a given time interval if moving objects including mechanical objects appear in a sensor‘s detecting area and depending on illumination level. Explosion-proof motion sensors DVG-SHAG operate in single-phase electric power systems of 230 VAC and 50/60 Hz frequency. Explosion-proof motion sensors DVG-SHAG operate on a principle of radio location with super high frequency waves 5,8 GHz, receiving echo reflected from the objects.
Scope of application - hazardous indoor and outdoor areas in accordance with explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) and areas hazardous with combustible dust ignition as per GOST IEC 61241-3-2011, 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.

SETTING
Regulator of illumination level allows to set illumination level, at which motion sensor closes the load. Minimum illumination level at which the load does not switch on is 2 lux. Maximum illumination level at which the load switches on is 2000 lux.
Regulator of delay allows to set time of the load connected to the sensor. Maximum operation time is 12 minutes. When sensor actuates within timer period of activity, countdown starts again.
Range capability regulator allows to set distance of detection of a moving object by a sensor. If sensor is installed at 2,5 m height, minimum position of the regulator is 1 meter, maximum is 4 meters.
