Intrinsically Safe Telephone

Intrinsically safe telephone for dangerous zone

The intrinsically safe telephone is an internationally tested explosion-proof telephone for any hazardous area.The intrinsically safe telephone is made of Sheet Molding Compound material. It has good sealing performance and waterproof level up to ip66. The explosion proof safe telephone is an industrial phone that is explosion proof and weatherproof telephone.

Instrinsically safe telephone work as atex equipment  made of GRP by die casting. The IECEx explosion proof telephone is rugged and durable. KNTECH design and manufacture the telephone with IECEX tertification and export to 50 countries.  This Explosion proof Instrinsically safe telephone works in Hazardous Area. The explosion proof telephone use in zone 1 and zone 2. It can also use in Division 2.Ex II 2 GD & Ex ii 2G IECEx Certified explosion proof telephone.

KNEx1 intrinsically safe automatic telephone and anti-noise automatic telephone are high-performance and high-reliability communication terminals successfully developed by adopting modern electronic technology and fully integrated circuits. It is matched with the mine safety coupler and can be connected with various existing ground switches or dispatching mainframes to form a coal mine production scheduling communication system. The telephone can also be applied to other harsh working environments with high temperature, high noise, high temperature and heavy pollution, such as power plants, coal preparation plants, steel plants and ports.

What is an intrinsically safe phone?

Intrinsic safety is an abbreviation of “intrinsic safety”. It is a type of explosion-proof electrical equipment that can be used in industrial areas where there are explosive gases, oil platforms, mines and other dangerous areas.

Intrinsically safe power supply, if not protected by other explosion-proof type, can only be installed in non-hazardous areas, but its output (power supply, signal) is intrinsically safe and can be connected to intrinsically safe equipment in hazardous areas, such as telephones ,the explosion proof phone.

What is intrinsically safe equipment?

Intrinsically Safe Type Abbreviation: Intrinsically Safe

Uses: Electrical or equipment explosion-proof category

Interpretation: By controlling the energy level of the device itself, it is lower than the critical condition for igniting the explosive gas under normal working or fault conditions, and does not generate sparks or temperatures lower than the igniting explosive gas, rather than being shielded or blocked by other means.

1. Intrinsically safe ignition protection

The special provisions for the design and inspection of such electrical equipment are included in the European standard EN 50 020, which are applied to explosives in intrinsically safe ignition protection.

Unlike other methods, intrinsically safe ignition protection involves not only a single device, but also the entire intrinsically safe circuit. If an explosive environment is not ignited by a spark or thermal effect in a circuit, the circuit is said to be an intrinsic type circuit.

In intrinsically safe equipment, appropriate measures must be taken to ensure that energy is limited to a small extent without igniting an explosive environment (including failures). All circuits in intrinsically safe equipment are designed in their own form. These devices are allowed to be used directly in the corresponding hazardous area depending on their explosion-proof rating. Auxiliary electrical equipment includes both intrinsically safe circuits and non-intrinsically safe circuits. They are usually used in safe places, but the cables enter dangerous places. Therefore, the auxiliary electrical equipment must also comply with the above-mentioned explosion-proof grade, that is, an auxiliary electrical equipment connected to the sensor or actuator in zone 0, must be an explosion-proof class 1 device.

  6, Ex p (aerated positive pressure type)

  7, Ex o (oil immersion type)

  8, Ex q (Zeng'an Zhongchong type)

Intrinsically safe: The energy of the circuit is limited by the relevant technology, so that the electrical energy generated in the electrical equipment generates sparks or hot surfaces that are not sufficient to detonate substances in the explosive environment.

Increased safety type: Through the design of the product, it can eliminate the detonation source of hot surface or electric arc or electric spark to achieve the purpose of explosion protection.

Molded type: A device or part of a device that may ignite an explosive environment is encapsulated in a substance to isolate the device or part thereof from substances in an explosive atmosphere for the purpose of explosion protection
