Explosion proof certification refers to a safety certification for equipment and products used in explosive hazardous areas. To meet the requirements of explosion-proof certification standards, certain measures must be taken to achieve it, which we call explosion-proof protection type. The common types of explosion-proof protection currently include intrinsic safety, explosion-proof, positive pressure, increased safety, and so on.
It can be seen that intrinsic safety is only one type of explosion-proof protection.
Different types of explosion-proof protection have different design requirements for products.
Intrinsic safety is a type of explosion-proof protection that limits electrical energy so that even in the event of a malfunction, the energy generated is insufficient to ignite the surrounding explosive environment. Therefore, intrinsic safety type has limitations on the current, voltage, capacitance, inductance, etc. of electrical equipment, and is generally applicable to low-power devices. At the same time, intrinsic safety also has clear requirements for the power supply method, plastic casing, wireless transmission, etc. of the equipment.
As a third-party organization that has long focused on the field of explosion-proof certification, Zhongnuo Testing has specialized engineers in intrinsic safety circuit design and structural design, who can provide technical consultation on explosion-proof circuit design, drawing, and rectification. They have rich experience in designing and obtaining certification for intrinsic safety ia, ib, and ic explosion-proof levels.
