UNSPSC 41111927: Pressure sensors

UNSPSC 41111927 Pressure sensors is a Commodity code that state and local governments are using to tag a diverse array of environmental monitoring and detection equipment that bears little connection to the nominal "pressure sensors" descriptor. Recent solicitations show the code applied to atmospheric gas-detection systems at water and wastewater facilities, environmental conditions monitoring systems for laboratory refrigeration and incubation equipment, ozone transfer standards and zero air generators, and even musical equipment and sound systems procurement. The code is being used by environmental agencies, water utilities, school districts, and university systems, often without clear alignment to the actual scope of work advertised. When the code does reflect its stated purpose — pressure or condition sensing — the work involves installation, training, maintenance planning, parts provisioning, and operator certification across water treatment plants, laboratory facilities, and distributed equipment networks.

Issuing bodies include state environmental protection agencies (Illinois EPA), state agricultural laboratories (Georgia Department of Agriculture), municipal water utilities (City of Phoenix), school districts (Clayton County Public Schools), and university systems (Texas A&M). Geographic activity spans Georgia, Illinois, Arizona, and Texas. Representative recent opportunities include the City of Phoenix Water Services Department's IFB 27-0435 (closed September 4, 2026) for atmospheric monitoring instruments—fixed installations to detect hydrogen sulfide, methane, chlorine, and other hazardous gases at water and wastewater lift stations and confined spaces, with a five-year term and requirements for local parts stock and 48-hour replacement availability; the Georgia Department of Agriculture Laboratory Division's RFQ 40200ERFQ0018662027 (closed August 21, 2026) for an environmental conditions monitoring system covering fifty-eight refrigeration and incubation units across Tifton and Atlanta facilities; and the Illinois Environmental Protection Agency's IFB 26-532EPA-LAB53-B-53209 (closed September 1, 2026) for a tandem mass spectrometer system for pesticide analysis in surface water, including on-site installation, training, and lifetime support. The code shows active use but inconsistent application to the category name.
