Product Advantages
- 3-Wire Compensation Design: Effectively eliminates lead wire resistance error, ensuring high measurement accuracy and stability, ideal for long-distance transmission.
- Surface Mount Patch Design: Ultra-thin adhesive patch for easy installation on flat/curved surfaces, no drilling required, fast response to surface temperature changes.
- High Temperature Resistant Cable: Fiberglass braided shielded cable with excellent insulation, anti-interference, and high temperature resistance, suitable for harsh industrial environments.
- Wide Compatibility: Standard PT100 output compatible with most PLCs, temperature controllers, and data acquisition systems.
- Customizable: Support for custom cable length, temperature range, and termination types to meet different application needs.
- Durable & Reliable: Sealed probe structure with waterproof and dustproof performance, long service life for continuous industrial monitoring.
Product Disadvantages
- Higher Cost Than 2-Wire Sensors: 3-wire design and platinum sensing element result in a higher price compared to 2-wire PT100 or thermocouple sensors.
- Surface Installation Limitation: Only suitable for surface temperature measurement, cannot be used for liquid/immersion temperature sensing without additional protection.
- Adhesive Durability: Long-term high-temperature or high-humidity environments may reduce the adhesive strength of the patch, requiring regular inspection.
- Requires Excitation Source: Unlike thermocouples, PT100 RTDs require an external excitation current source for measurement, increasing system complexity.
- Limited Temperature Range: Not suitable for ultra-high temperature applications above 250°C, compared to high-temperature thermocouples.
