The sensor features a 6-inch probe that inserts directly into a duct section and outputs a resistance signal across a 20 kOhm range, allowing a compatible controller or thermostat to monitor supply or return air temperature. Non-linear NTC-style sensors of this type are common in residential and light commercial forced-air systems where accurate air temperature feedback is required for proper equipment staging and control logic. Installation is typically performed by a licensed HVAC technician.\u003c\/p\u003e\u003cp\u003eThis sensor is suited for duct temperature sensing applications in forced-air heating and cooling systems. The 6-inch probe length is appropriate for standard residential and light commercial duct sizes, providing reliable insertion depth for accurate air-stream readings. It is used wherever a controller requires a duct-mounted input signal to regulate equipment operation based on measured air temperature.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-linear resistance output across a 20 kOhm range for compatible control systems\u003c\/li\u003e\n\u003cli\u003e6-inch duct probe length for reliable air-stream temperature measurement\u003c\/li\u003e\n\u003cli\u003eDesigned for direct duct insertion in forced-air HVAC applications\u003c\/li\u003e\n\u003cli\u003eCompact sensor form factor suited for both supply and return duct mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement duct temperature sensor for compatible ALLIED AIR Enterprises HVAC control systems requiring a non-linear 20 kOhm duct probe input.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the air handler or furnace before removing or installing the sensor. The probe is inserted through a field-drilled or existing port in the duct wall and secured per manufacturer instructions. Verify controller compatibility and sensor wiring connections before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Type\u003c\/strong\u003e: Non-Linear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance\u003c\/strong\u003e: 20 kOhm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProbe Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Duct Air Temperature Sensing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ALLIED AIR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19l22\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED AIR","offers":[{"title":"Default Title","offer_id":51467650695474,"sku":"19L22","price":109.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945806.jpg?v=1783909390","url":"https:\/\/voomisupply.com\/products\/allied-air-19l22-air-temperature-sensor-20-kohm-6-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
