TC66 Explosion-proof TC Thermometer
- SKU:
- TC66 Explosion-proof TC Thermometer series
- Weight:
- 0.00 Grams
Description
Application
The TC66 Explosion-proof Thermometer is engineered for challenging and safety-critical environments, particularly within the chemical, oil & gas, and energy industries. With its durable protection tubes and specialized materials, it can withstand harsh conditions, corrosive elements, and extreme pressures. For enhanced measurement precision and reliability, an optional head transmitter supporting all major communication protocols is available, offering superior performance compared to direct-wired sensors.
Key Applications
- Heavy-duty industrial processes
- Oil & Gas sector operations
- Temperature range: –40 to 1,100 °C (–40 to 2,012 °F)
- Static pressure capability: up to 100 bar (1,450 psi)
- IP68-rated protection class
Benefits
- Certified protection types for hazardous areas: Intrinsic safety (Ex i.a.), flameproof (Ex d), non-sparking (Ex nA)
- High compatibility with various inserts, designed according to DIN 43772 standards
- Extended neck design to shield the head transmitter from excessive heat
- Modular design offering flexibility with standard terminal heads (DIN EN 50446) and customized immersion lengths for specific needs
