The Coantec X5 series 3D measurement industrial endoscope holds an explosion-proof certificate (SYEx25.01163X) issued by a nationally accredited institution. This certification acts as a mandatory permit for entering hazardous work areas such as petroleum, chemical, and gas industries. It verifies that the equipment complies with national standards, incorporates an intrinsically safe design, and is approved for safe operation in explosive atmospheres. In hazardous locations where traditional inspection methods are limited or unsafe, the X5 series enables testing without shutdowns, providing a safe, efficient, and professional solution for internal equipment assessment.
I. Understanding the Explosion-Proof Certification: A Requirement for Hazardous Areas
Technical Meaning of the Explosion-Proof Marking: Ex ib IIC T4 Gb
Ex ib: Denotes intrinsically safe protection. It ensures that any electrical sparks or thermal effects produced by the equipment under all operating conditions remain below the energy level required to ignite a specific hazardous atmosphere.
IIC: Indicates suitability for the most rigorous explosive gas environments, including hydrogen and acetylene.
T4: Specifies that the maximum surface temperature of the equipment will not exceed 135°C.
Gb: Represents a high level of equipment protection, meeting the requirements for use in both Zone 1 and Zone 2 hazardous locations.
Certification Standards Compliance:
GB/T 3836.1-2021 Explosive Atmospheres – Part 1: Equipment General Requirements
GB/T 3836.4-2021 Explosive Atmospheres – Part 4: Equipment protection by intrinsic safety “i”
II. Core Advantages of the X5’s Explosion-Proof Certification
1. Safe and Compliant Operation
Enables live inspection in Zone 1 and Zone 2 explosive gas environments.
Eliminates the need for equipment disassembly and process shutdowns required by traditional methods.
Complies with internationally recognized explosion-proof standards.
2. Professional Inspection Capabilities
High-Definition Imaging: Delivers clear visual data even in challenging hazardous environments.
3D Measurement Function: Allows for precise dimensional analysis of defects, cracks, or corrosion.
Intrinsically Safe Design: Provides comprehensive safety protection, from internal circuitry to external housing.
3. Important Usage Constraints
Must use only the certified, matching battery system provided.
Charging or disassembling the unit in a hazardous area is strictly prohibited.
The certification is valid only for the specific model(s) listed on the certificate.
