Welcome to visit Shenzhen Yuantong Website!

The article will take you 5 minutes to understand some key factors of how to select a industrial telephone.

Industrial Telephones are used in harsh environment to make sure the esstencial communication for daily and emergency.

1. Environmental Suitability

• Durability: Industrial telephones should withstand harsh conditions like extreme temperatures, humidity, dust, and vibrations. Look for models that are rugged and built specifically for industrial use.
• Ingress Protection (IP) Rating: Check the IP rating of the phone. A higher IP rating (like IP65 or above) indicates better protection against dust and water.

2. Functional Requirements

• Sound Quality: Ensure the telephone provides clear audio, especially in noisy environments. Noise-canceling features can be beneficial.
• Emergency Features: Consider models that have emergency call functions or alarms for enhanced safety.
• Multi-functional Capabilities: Some phones come with intercom or broadcasting features, which may be useful depending on your needs.

3. Connectivity

• Network Compatibility: Make sure the telephone supports the required network types (like VoIP or analog lines) to integrate smoothly with your existing systems.
• Wireless Options: If mobility is essential, consider wireless telephones for easier movement around the facility.

4. Installation and Maintenance

• Ease of Installation: Choose devices that are easy to set up and configure to minimize installation time and complexity.
• Maintenance Needs: Look for phones that are easy to repair and maintain, reducing long-term costs.

5. Cost-Effectiveness

• Budget Considerations: Set a budget and compare options. Remember, the cheapest option isn’t always the best; consider quality and features.
• Long-term Investment: Assess the durability and warranty options. Investing in reliable equipment can save money over time.

6. Brand and Support

• Brand Reputation: Opt for well-known brands that are recognized for quality and reliability.
• After-Sales Support: Check the manufacturer’s warranty and customer service options to ensure you have assistance if needed.

Safety Knowledge: Certifications and Ratings

Common Certifications

• CE Marking: Indicates that the product meets EU safety, health, and environmental protection standards.
• UL Certification: Underwriters Laboratories (UL) certification ensures products meet specific safety standards in the U.S.
• ATEX Certification: Required in Europe for equipment used in explosive atmospheres, ensuring that devices are safe to use in such environments.
• IECEx Certification: An international standard for equipment used in explosive environments, similar to ATEX but recognized globally.

Explosion-Proof Ratings

1. Americas

United States

• NEC (National Electrical Code):
  • Classes:
    • Class I: Flammable gases
      • Division 1: Areas where flammable gases are present under normal conditions
      • Division 2: Areas where flammable gases are not normally present but may occur in case of a fault
    • Class II: Combustible dust
      • Division 1: Areas where combustible dust is present under normal conditions
      • Division 2: Areas where combustible dust is not normally present but may occur in case of a fault
    • Class III: Combustible fibers
      • Areas where combustible fibers are present

Canada

• CSA (Canadian Standards Association):
  • Follows a classification similar to NEC, compliant with Canadian electrical safety standards.

2. Europe

ATEX (ATmosphères EXplosibles)

• Classification:
  • Equipment Categories:
    • Category 1: Equipment that is safe to use in environments where explosive gas atmospheres are present
    • Category 2: Equipment that is safe to use in environments where explosive gas atmospheres may occasionally occur
    • Category 3: Equipment that is safe to use in environments where explosive gas atmospheres are not likely to occur
  • Zone Classification:
    • Zone 0: Areas where explosive gas atmospheres are frequently present
    • Zone 1: Areas where explosive gas atmospheres are occasionally present
    • Zone 2: Areas where explosive gas atmospheres are not likely to occur under normal operation

IECEx (International Electrotechnical Commission Explosive)

• An international standard similar to ATEX, aimed at providing a unified explosion-proof certification standard globally.
