J-Type Thermocouple Temperature Sensor (J3-100 PTFE)
This Type J Thermocouple features an extended 100mm probe, providing the perfect balance between reach and rigidity. Utilising an Iron/Constantan junction, this sensor is highly effective for monitoring temperatures in reducing atmospheres or vacuum applications where Type K sensors might degrade.
Technical Specifications
| Feature | Specification |
| Sensor Type | Type J (Iron / Constantan) |
| Probe Dimensions | 6mm (Diameter) x 100mm (Length) |
| Probe Material | 316 Stainless Steel (Corrosion Resistant) |
| Lead Wire Length | 1.5m (1500mm) |
| Insulation Material | PFA / PTFE (Teflon) - Waterproof & Acid Resistant |
| Color Coding | Black (+) / White (-) [IEC 60584 Standard] |
| Temperature Range | -40°C to +250°C |
| Termination | Bare tails (Stripped ends) |
Key Features
-
Extended Reach: The 100mm probe length allows for deeper immersion into thermal blocks, process pipes, or medium-sized tanks.
-
Stable Measurement: Type J is preferred for its stability in environments with limited oxygen (reducing atmospheres), where it maintains high accuracy.
-
High-Grade Insulation: The PFA-coated leads are designed to withstand harsh industrial environments, offering resistance to moisture, chemicals, and oils.
-
Industry Standard Wiring: Black (+) and White (-) lead wires ensure easy installation and compatibility with J-type instrumentation.
Applications
-
Plastic & Rubber Production: Temperature control for molds and heating plates.
-
Vacuum Furnaces: Monitoring heat levels in oxygen-depleted environments.
-
Chemical Processing: Durable enough for immersion in mildly corrosive liquids.
-
Lab Equipment: Ideal for use in autoclaves and environmental chambers.
