Product Description
The AN-3334-2 is a resistor thermocouple lead spool that stabilizes circuit resistance in aircraft temperature indication systems. This AN-standard component works with Type J or K thermocouples to match instrument calibration in engine EGT (exhaust gas temperature) and CHT (cylinder head temperature) circuits. The spool installs in-line with thermocouple leads, maintaining accuracy and preventing signal drift.
Verify compatibility with your aircraft's Illustrated Parts Catalog before installation per maintenance manual requirements.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
