This precision \u003cstrong\u003e10k-T2 thermistor\u003c\/strong\u003e delivers highly accurate resistance-to-temperature feedback, ensuring your Building Automation System (BAS) or local controller maintains tight environmental tolerances. Featuring \u003cstrong\u003e5-foot leads\u003c\/strong\u003e, the STE-1011 offers the flexibility required for varied installation points, from duct-mounted airflow monitoring to ambient space sensing in air handling units or rooftop packages.\u003c\/p\u003e\n\n\u003cp\u003eEngineered to match the standard \u003cstrong\u003e10k ohm Type II resistance curve\u003c\/strong\u003e, this sensor is a direct replacement or upgrade for systems requiring a 10K-T2 reference. The lead wires are ruggedized for duty in plenum environments, reducing the risk of signal interference or physical degradation in high-vibration HVAC settings. For technicians managing \u003cstrong\u003eVAV controllers\u003c\/strong\u003e or terminal unit diagnostics, the STE-1011 provides the stable, repeatable data needed to optimize thermal efficiency and prevent equipment cycling. Its high-precision thermistor bead is calibrated for long-term drift resistance, maintaining system setpoint accuracy without the need for frequent field recalibration.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMatches industry-standard \u003cstrong\u003e10,000 ohm @ 77??F (25??C)\u003c\/strong\u003e Type II resistance curves for broad controller compatibility.\u003c\/li\u003e\n  \u003cli\u003eExtended \u003cstrong\u003e5-foot lead wire length\u003c\/strong\u003e simplifies wiring in large air handlers and complex mechanical rooms.\u003c\/li\u003e\n  \u003cli\u003eRobust construction supports \u003cstrong\u003eHVAC temperature monitoring\u003c\/strong\u003e in both supply air and return air applications.\u003c\/li\u003e\n  \u003cli\u003eHigh sensitivity to temperature fluctuations allows for rapid controller response and improved energy management.\u003c\/li\u003e\n  \u003cli\u003eCompact sensor profile permits installation in tight spaces or direct mounting within custom probe assemblies.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the STE-1011 compatible with 10k Type III controllers?\u003c\/strong\u003e\u003cbr\u003e\nNo, this is a \u003cstrong\u003e10k Type II thermistor\u003c\/strong\u003e. While both have a base resistance of 10,000 ohms at 25??C, their resistance curves diverge at different temperatures. Always verify your controller's input requirements before installation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan the 5-foot leads be extended in the field?\u003c\/strong\u003e\u003cbr\u003e\nYes, you can extend the leads using shielded twisted pair wire. Ensure proper \u003cstrong\u003eHVAC sensor wiring\u003c\/strong\u003e techniques are used to minimize added resistance, which can cause temperature offsets in the controller readings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat applications is this thermistor used for?\u003c\/strong\u003e\u003cbr\u003e\nThe STE-1011 is commonly used for \u003cstrong\u003edischarge air temperature sensing\u003c\/strong\u003e, room temperature monitoring, and as a feedback loop for chilled water or heating coil performance.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
