HVAC Duct & Immersion Temperature Sensor (1S9SW102)

The hardware functions as an industrial-grade duct and immersion temperature field sensor explicitly engineered to deliver high-resolution thermal monitoring across commercial building ventilation shafts, air ducts, and utility piping infrastructures. It features a passive NTC10k measurement tracking core operating across an expansive temperature sensing spectrum from -50°C to +150°C with a tight structural accuracy tolerance of ±1%, providing highly stable air or gaseous medium telemetry with a low operational current footprint to proactively neutralize element self-heating errors. The sensing mechanism is housed inside a rugged, high-durability stainless steel immersion probe measuring exactly 135mm long by 7mm wide, which seamlessly adapts into liquid pipeline systems when inserted within a secondary thermowell pocket sleeve.

To survive rigorous outdoor and demanding plant deployments over long horizons, the connection head is constructed from a flame-resistant white IP65-rated polyamide housing fortified with light-stable pigments and titanium dioxide additives that reflect the full light spectrum to permanently counteract photochemical polymer degradation and fading. The wire-free module handles centralized flush ceiling or flat surface wall mounting over standard junction box layouts, utilizing high-stability internal wired screw terminal blocks supporting cross-sections up to 1.5mm² while maintaining strict compliance across standard building directives.
