UNSPSC 41112410: Pressure transmitters

UNSPSC 41112410 Pressure transmitters is a Commodity code that encompasses pressure sensing and transmission equipment deployed across water, wastewater, and process-control infrastructure at municipal facilities. State and local governments procure pressure transmitters as standalone instrumentation, as components within integrated process-control systems, and as replacement parts for existing automated monitoring and control networks. The issuing bodies are primarily water and wastewater utilities within city and county governments. Tampa's Water Department, Tampa's Wastewater Department, Phoenix Water Services, Collier County Water and Wastewater, and Gallup's water supply system are repeat active buyers. Solicitation types include RFQs for inventory gauges and replacement equipment, IFBs for multi-year supply contracts with approved manufacturer lists, and Notices of Intent to Single Source for authorized distributor arrangements when equipment integrates with legacy SCADA systems or process control networks designated critical to regulatory compliance.

Recent activity is concentrated in Florida and Arizona. The City of Phoenix Water Services Department issued IFB 26-0398 in August 2026 for a five-year pressure and temperature instrumentation contract (pressure transmitters, pressure switches, gauges, diaphragm seals, temperature transmitters, thermowells, and related accessories) from approved manufacturers including ABB, Emerson, Endress+Hauser, Honeywell, Siemens, and VEGA, with sealed offers due August 18, 2026, requiring vendors to maintain local stock and provide next-business-day fulfillment. The City of Tampa, Florida issued RFQ 26-P-00548 in September 2026 for inventory gauges (pressure gauges including Ashcroft and WIKA products) with quotes due October 6, 2026, on a one-year award basis. Collier County, Florida issued a Notice of Intent to Single Source (PUR17875) in September 2026 for Siemens pressure and temperature transmitters, level sensors, and related process instrumentation supporting the county's water and wastewater SCADA systems, with a three-year term from October 1, 2026. The City of Tampa also single-sourced Allen Bradley and Rockwell Automation instrumentation and support through an authorized distributor for its Water, Wastewater, and Waste to Energy departments (ISS 27-X-00020, objection deadline October 14, 2026). Contracts typically require DBE-N small business participation plans, local stocking and same-day or next-business-day fulfillment capability, minimum three-year vendor history supplying water and wastewater utilities, and firm-and-fixed pricing for the initial contract period with annual escalation provisions requiring advance notice and supporting documentation.
