UNSPSC 41112405: Pressure or vacuum recorders

UNSPSC 41112405 Pressure or vacuum recorders, a Commodity code, covers instrumentation equipment for monitoring and recording pressure, temperature, and related process variables at water, wastewater, and waste energy facilities. State and local governments procuring under this code are sourcing pressure transmitters, pressure gauges, temperature transmitters, thermowells, process recorders, flow meters, level controllers, and related accessories—often as critical components of SCADA systems and process monitoring infrastructure at municipal utilities. Issuing bodies include city water and wastewater departments, county water authorities, and solid waste facilities; the City of Tampa and City of Phoenix Water Services Department have posted multiple opportunities in recent months. The work spans equipment procurement, authorized distributor relationships, spare parts availability, factory service support, and integration with existing control systems designated essential to compliance with permit requirements and operational reliability.

Recent activity concentrates in Florida and Arizona. The City of Tampa issued an Intent to Single Source (ISS 27X00020, posted October 8, 2026, objection deadline October 14, 2026) for Allen Bradley and Rockwell Automation products and support services across its Water, Wastewater, and Waste to Energy Departments; the City also posted RFQ 26P00548 (posted September 16, 2026, quotes due October 6, 2026) for inventory gauges including chlorine, Ashcroft, and WIKA pressure gauges. The City of Phoenix Water Services issued IFB 26-0398 (posted August 18, 2026, offers due August 18, 2026) for pressure and temperature instrumentation equipment—a five-year contract covering transmitters, gauges, switches, and diaphragm seals from manufacturers including Honeywell, Siemens, and Emerson, with mandatory vendor stocking and same-day or next-business-day fulfillment capability. Collier County, Florida posted a Notice of Intent to Single Source (PUR17875, posted September 10, 2026, challenge period closing October 1, 2026) for Siemens process instrumentation including pressure transmitters and process recorders integrated with the County's SCADA system at water and wastewater facilities. The City of Gallup, New Mexico also issued an RFP for SCADA system upgrade (RFP 2025202603, posted June 29, 2026, proposals due December 11, 2025) encompassing hardware, software, and communications infrastructure at 46 water system locations.
