Core Value

The K Type Thermocouple Wire Metal Shielded Temperature Cable is engineered for high-precision temperature sensing and signal transmission in noisy industrial environments. Built with high-purity NiCr-NiSi (Chromel/Alumel) alloy conductors complying with ANSI/IEC Special Class 1 accuracy standards, this extension/compensation cable delivers reliable, millivolt-level temperature feedback to PID controllers and data loggers.

Encased in a premium Metal Insulation Jacket with an integrated Metal Braid Shielding (Stainless Steel or Tinned Copper), it provides an impenetrable barrier against chemical corrosion, moisture ingress, and electromagnetic interference (EMI/RFI). Operating continuously across an extreme thermal window of -200°C to +260°C (-328°F to +500°F), it prevents signal drift and measurement errors in compact mold channels, chemical processing lines, and high-vibration machinery. BACKED BY 30+ YEARS MANUFACTURING EXPERIENCE and UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS for ultimate sensing accuracy and zero-leakage signal integrity.

• ✓ Class 1 High Accuracy Calibration: Precision Chromel/Alumel alloy conductors guarantee ANSI Class 1 (±1.1°C or ±0.4%) temperature tolerance.
• ✓ PTFE Chemical & Moisture Barrier: Non-reactive PTFE insulation prevents acid, oil, moisture, and solvent penetration from degrading signals.
• ✓ EMI/RFI Metal Braid Shielding: High-density metal braid eliminates electrical noise and interference from adjacent motor drives and heating lines.
• ✓ Broad Temperature Range: Performs reliably across extreme thermal ranges from cryogenic -200°C up to +260°C continuous heat.
• ✓ Flexible & Abrasion-Resistant: Low friction PTFE outer sheath and metal armor braid allow easy pulling through tight conduit and mold channels.
• ✓ Standardized Color Coding: Fully compliant with ANSI (Yellow/Red) and IEC (Green/White) standard thermocouple polarity identification.
• ✓ Reliable Quality: 30+ YEARS MANUFACTURING EXPERIENCE guarantees precise alloy conductor purity and resistance uniformity.
• ✓ Quality Assured: UNDERGOES MULTIPLE RIGOROUS QUALITY CHECKS including millivolt output calibration, continuity, and insulation resistance testing.
• ✓ Global Compliance: ANSI, IEC, CE, RoHS, and ISO 9001 certified.

HT-Heater vs Standard Market Thermocouple Wires

Installation & Integration Guidelines

• Polarity Verification: Verify correct lead polarity prior to connecting to PID controllers or transmitters (For ANSI Type K: Yellow = Positive, Red = Negative; For IEC: Green = Positive, White = Negative).

• Shield Grounding: Connect the metallic shielding braid to a clean instrument earth ground at one end only (preferably at the controller) to prevent ground loop noise interference.

• Avoid Sharp Bending: Maintain a minimum bend radius of at least 5 times the cable outer diameter to prevent kinking the internal alloy conductors or outer shield.

• Separate Power Cables: Route thermocouple signal cables in separate conduit or troughs away from high-voltage AC power lines and heavy motor cables to minimize inductive coupling.

• Sealed Junctions: Use proper high-temperature thermocouple connectors or ceramic terminal blocks when splicing extension cables to maintain calibration accuracy.
