KTH15 explosion proof phone KTH15 phone, KTH15 proof phone manufacturers, KTH15 explosion proof phone price KTH15 phone has a beautiful appearance, small size, light weight, reliable performance characteristics. Can replace similar products at home and abroad, explosion-proof type: Mine intrinsically safe, explosion-proof mark: ExibI. The machine (after the associated device attached) telephone coupler and scheduling switch connected to form a communication system via its associated equipment. Zmjt11 KTH15 proof phone is intrinsically safe electrical equipment, two-way audio Fa Fa, for coal mine containing gas (methane) of explosive gas mixtures dangerous places, as the communication liaison purposes. Through its associated equipment and program-controlled telephone coupler can be connected with the scheduling switch, connected to its cable length 5km. KTH15 proof phone use environmental conditions a. Ambient temperature: -10 ℃ ~ + 40 ℃; b. Relative humidity: ≤95% (+ 25 ℃); c. Atmospheric pressure: 80kPa ~ 106kPa; d. Environmental Noise: ≤60dB (A); e. No significant vibration and shock place; f. There is an explosive mixture, but no place to destroy insulation corrosive gases. KTH15 explosion proof phone principle and purpose KTH15 phone shell with antistatic reinforced polyester production, waterproof, dustproof, corrosion, protection class IP65, suitable for extremely harsh environments. Using wall-mounted, using the newly developed hook switch bodies, without any moving parts on the phone. KTH15 phone can be used in coal mine explosion in high noise environments, such as the mining face, loading point and other places, as an anti-noise communication terminal. KTH15 proof phone also can be used in other high-temperature, high-noise, high humidity and heavy pollution of poor working conditions, such as power plants, coal preparation plant, steel plants, tunnels, ports, chemical plants, etc. as an industrial communication terminal.
