Technologies Used
High-temp RFID tags incorporate specialized technologies to ensure performance:
- Chip Packaging: Heat-resistant encapsulation to prevent failure
- RFID Protocols: Typically ISO/IEC 18000-6C (UHF), with some HF/LF variants
- Material Innovation:
- Zirconia/Alumina Ceramics: High dielectric constant for better RF performance on metal
- Epoxy Resin Substrates: Used in PCB tags for metal shielding
- Polyimide Coatings: Flexible and weather-resistant
Construction Details
- Encapsulation: Tags are sealed using high-temp adhesives, epoxy, or glass
- Form Factors:
- Embedded in molds or tools
- Surface-mounted with high-temp glue
- Encased in metal or ceramic shells
- Durability Enhancements:
- Shock and vibration resistance
- Corrosion-proof coatings
Application Areas
High-temp RFID tags are indispensable in:
- Metal Smelting & Foundries: Tracking ladles, molds, and furnace components
- Automotive Manufacturing: Paint lines, engine part tracking
- Aerospace & Defense: Monitoring components exposed to extreme heat
- Medical Sterilization: Surgical instrument tracking during autoclaving
- Chemical & Petrochemical: Asset tracking in corrosive, high-temp zones
- Electronics (SMT): Work-in-process tracking during soldering and reflow
Advantages
- Extreme Heat Resistance: Operate reliably in environments up to 1000C
- Non-Contact Identification: Efficient tracking without line-of-sight
- Durability: Withstand shock, corrosion, and vibration
- Traceability: Real-time monitoring and data collection
- Process Compliance: Ensures quality control in harsh conditions
- Flexible Deployment: Suitable for flat, curved, or embedded surfaces
