.KXB127 Type explosion-proof and intrinsically safe language of sound and light alarm KXB127 type flameproof and intrinsically safe language of sound and light alarm factory direct KXB127 type flameproof and intrinsically safe language of sound and light alarm manufacturers custom KXB127 type flameproof and intrinsically An audible alarm type language KXB127 latest offer proof and intrinsically safe type language of sound and light alarm composed Detailed KXB127 type flameproof and intrinsically safe language of sound and light alarms present, China's packaging machinery companies manufacturing skill levels can KXB127 type flameproof and intrinsically safe language of sound and light alarm weak force, development has KXB127 type flameproof and intrinsically safe language audible alarm can not keep up the pace of competition in the market. Now some innovative packaging machinery companies have increased energy KXB127 type flameproof and intrinsically safe language of sound and light alarm force, positive tone KXB127 type flameproof and intrinsically safe language sound and light alarm whole product structure, basically meet the market demand, but still Some products rely on imports. I KXB127 type flameproof and intrinsically safe language of sound and light alarm packaging machinery in the country KXB127 type flameproof and intrinsically safe language of sound and light alarm small enterprises, a lot of financial support to carry out the miniaturization KXB127 Flameproof and intrinsically safe language of sound and light alarm, digital direction, and the upgrading of skills KXB127 type flameproof and intrinsically safe language of sound and light alarm surgery, replacement of equipment, etc., while technical KXB127 type flameproof and intrinsically safe language of sound and light alarm surgery is the lack of talent, but also left many businesses struggling. In recent years, with the KXB127 type flameproof and intrinsically safe language of sound and light alarm level of technology KXB127 type flameproof and intrinsically safe language of sound and light alarm growing gap with foreign companies to invest in research and development accounted for 1% of enterprises KXB127 type flameproof and intrinsically safe language sound and light alarm sales, prices KXB127 type flameproof and intrinsically safe language of sound and light alarm industry to survive, can account for barely 2%, 5% When only KXB127 type flameproof and intrinsically safe language of sound and light alarm competitiveness, and investment in research and development for an average of less than 1%. I. Overview KXB127 type flameproof and intrinsically safe language audible alarm (coal safety ID: MHE120004) is mainly used in coal mine sites contain explosive gases, for roadway entrance transport, export or Sanchakou, corners or sound RBI light alarm, also can be used to enhance the sound and light alarm Shaft, cross rails instructions, turn the alarm to ensure work safety. Second, the product features of the alarm one two chambers separated intrinsically safe explosion chamber and the chamber, the circuit uses an integrated voltage comparator, high degree of electrical inspiration optocoupler devices, modular design. Overall layout is reasonable, small size and light weight. The alarm has two states, one standby; the second is an alarm condition. The operator of continuous operation for two or more buttons, alarms into alarm status, alarm process operator press a button to stop the alarm, the alarm into a standby state. The device may also be used simultaneously and bells strung together, the same operation method. Third, the main technical parameters Operating voltage: AC127V Working current: ≤0.3mA, intrinsically safe parameters: DC12.5V, 1A, sound loudness: not less than 85dB, optical signal visible distance optical signal visible in the dark at 40m.
