High Performance J Type Thermocouple Compensating Cable with FEP Insulation
Product Overview
Our J-type thermocouple extension wire with FEP (Fluorinated Ethylene Propylene) insulation is engineered for precise temperature signal transmission in demanding industrial environments. The FEP insulation provides superior electrical insulation, high-temperature tolerance, and chemical resistance, making it ideal for applications in chemical plants, power generation facilities, and food processing industries.
Key Features
- Accurate Signal Transmission: Maintains precise thermoelectric signal transfer from J-type thermocouples to measurement devices
- High-Temperature Resistance: FEP insulation withstands continuous operation up to 200°C with higher short-term peaks
- Chemical Resistance: Excellent protection against acids, alkalis, and solvents in corrosive environments
- Reliable Insulation: Superior electrical insulation minimizes interference for stable signal transmission
- Flexible Design: Easy installation in tight spaces with complex routing requirements
- Durable Construction: Resistant to aging, UV radiation, and mechanical abrasion for long service life
