Product Overview

The EGT N-Type Thermocouple is a specialized temperature sensing solution engineered for exhaust gas temperature (EGT) measurement in harsh industrial environments. With a temperature range of -200°C to 1300°C (-328°F to 2372°F) and exceptional stability, it delivers accurate data for engine performance optimization, emissions control, and equipment safety monitoring. Crafted with high-purity Nicrosil-Nisil alloy conductors, this thermocouple offers superior corrosion resistance, oxidation resistance, and long-term reliability in extreme heat and gas flow conditions.

Key Features

Wide Temperature Range: Operates reliably from -200°C to 1300°C, ideal for high-temperature EGT monitoring in engines, turbines, and industrial burners.

Precision Measurement: Class 1 accuracy (±1.5°C or ±0.4% of measured value, whichever is larger) ensures trustworthy data for critical applications.

Durable Construction: Nicrosil-Nisil alloy conductors resist corrosion, oxidation, and thermal shock; optional Inconel or ceramic protection tubes enhance durability in harsh exhaust environments.

Fast Response Time: Optimized probe design minimizes thermal mass, enabling quick detection of temperature fluctuations (response time <1 second in gas flow).

Customizable Configurations: Available in various probe lengths (50mm-500mm), diameters (3mm-8mm), and termination types (screw terminals, connector plugs, bare leads) to fit specific installation requirements.

Wide Compatibility: Suitable for gasoline/diesel engines, marine propulsion systems, industrial boilers, gas turbines, and exhaust aftertreatment systems.
