High Performance J Type Thermocouple Compensating Cable with FEP Insulation Precision Temperature Transmission
Product Description
J – type Thermocouple Extension Wire with FEP Insulation
Product Overview
The J – type thermocouple extension wire with FEP (Fluorinated Ethylene Propylene) insulation is a specialized cable designed for accurately transmitting the thermoelectric potential generated by a J – type thermocouple to a measuring instrument. The FEP insulation offers excellent electrical insulation properties, high – temperature resistance, and chemical resistance. This type of extension wire is suitable for a wide range of industrial applications, including temperature measurement in chemical plants, power generation facilities, and food processing industries where exposure to harsh chemicals, high temperatures, or corrosive environments may occur.
Key Features
- Accurate Signal Transmission: Ensures precise transfer of the thermoelectric signal from the J – type thermocouple to the measuring device, minimizing errors in temperature measurement.
- High – Temperature Resistance: The FEP insulation can withstand continuous operating temperatures up to [specific temperature, e.g., 200°C] and short – term peaks even higher, making it suitable for high – temperature applications.
- Chemical Resistance: Resistant to a wide variety of chemicals, including acids, alkalis, and solvents, protecting the wire from degradation in corrosive environments.
- Excellent Electrical Insulation: Provides reliable electrical insulation, reducing the risk of electrical interference and ensuring stable signal transmission.
- Flexibility: The wire is flexible, allowing for easy installation in tight spaces and complex routing requirements.
- Long – term Durability: Designed for long – term use, with good resistance to aging, UV radiation, and mechanical abrasion.
