Fire Detector Sensing Element, Continuous Loop D2370-33

Technical Description

High-reliability pneumatic continuous-loop fire and overheat sensing element assembly designed for engine nacelle or auxiliary power unit (APU) thermal zone monitoring. Features a highly flexible, slender stainless steel sensing tube filled with a specialized gas-evolving material that triggers internal pressure-actuated alarm switches upon exposure to critical localized threshold temperatures. Outfitted at both terminal ends with heavy-duty threaded coupling nuts protected by red vinyl storage caps, ensuring an airtight mechanical connection into the aircraft fire detection circuit network. Delivered in a factory-coiled configuration with an attached multilingual instruction card explicitly warning against straightening the sensitive element line between connections to prevent internal core damage and maintain strict safety calibration requirements.
