Fast-Response Type J Thermocouple: Φ1.5mm Probe with High-Temp Kapton Lead Cable
Product Overview
The Grounded Type J (Iron/Constantan) thermocouple is engineered for industrial and laboratory applications where space is extremely limited and thermal response time is critical. Featuring an ultra-slim $Phi1.5text{mm}$ stainless steel probe, this sensor minimizes thermal lag, providing near-instantaneous temperature data.
The probe is paired with a 1-meter Kapton-insulated lead wire, a high-performance polyimide material known for its exceptional dielectric strength and stability in high-temperature or vacuum environments. The grounded junction ensures the thermocouple is in direct contact with the probe tip for maximum heat transfer efficiency.
Technical Features
-
Ultra-Slim 1.5mm Diameter: The low thermal mass of the 1.5mm probe allows it to react to temperature fluctuations significantly faster than standard sensors.
-
Grounded Junction Design: By welding the sensor junction directly to the sheath tip, we achieve the fastest possible response time—ideal for dynamic thermal profiling.
-
Premium Kapton (Polyimide) Lead Wire: 1 meter of high-temp Kapton wire that remains flexible and electrically stable from -260°C up to +260°C (continuous use).
-
250mm Stainless Steel Probe: Provides 250mm of rigid reach for immersion into manifolds, small-diameter tubes, or complex machine parts.
-
Reinforced Plastic Transition: A durable plastic transition sleeve protects the connection between the rigid probe and the flexible lead wire, ensuring long-term strain relief.
