UNSPSC 41112225: Resistance temperature detector RTD

A wire wound and thin film device that measures temperature using the physical principle of the positive temperature coefficient of electrical resistance of metals. The hotter they become, the larger or higher the value of their electrical resistance.

UNSPSC 41112225 Resistance temperature detector RTD is a Commodity code describing temperature-sensing components, but the recent state and local opportunities tagged under it show minimal activity directly aligned with the code's nominal scope. The City of Tampa's two recent solicitations—one for wastewater inventory components (front panels, pressure switches, and process meters) and another for thermocouples with thermowells for the McKay Bay Waste-to-Energy Facility—include temperature-measurement hardware but do not focus on resistance temperature detectors as their primary procurement. Atlanta Public Schools' two parallel RFQs for commercial kitchen equipment repair and preventive maintenance services are unrelated to RTD procurement. State and local purchasing offices appear to use this code inconsistently or infrequently for targeted RTD buys.

The issuing bodies active under this code include municipal utilities (Tampa's wastewater and solid waste divisions) and, to a lesser extent, school districts, though the recent examples show limited volume and commodity focus. Geographic activity is concentrated in Florida and Georgia based on the current posting set, with Tampa appearing twice. Representative recent opportunities include the City of Tampa's May 2026 RFQ (26P00315) for 24 thermocouples with thermowells for delivery to McKay Bay Waste-to-Energy Facility with a May 12, 2026 response deadline, and the City of Tampa's July 2026 ITB (26P00425) for wastewater inventory components (panels, switches, meters) with response due August 6, 2026, restricted to Small Local Business Enterprise–certified bidders with a 5 percent bid discount. The code shows insufficient recent activity to support a sustained business development strategy.
