UNSPSC 41112100: Transducers

UNSPSC 41112100 Transducers is a Class code covering specialized sensing and monitoring equipment that state and local governments procure for water management, wastewater treatment, and utility infrastructure. Recent solicitations show state and local buyers acquiring radar level sensors for lift-station monitoring, vibration and temperature transmitters with signal conditioning for booster stations, pressure transducers for groundwater and surface-water monitoring, and isolation amplifiers for signal isolation in multi-department utility systems. The work centers on equipment integration with existing SCADA infrastructure, often requiring compatibility with deployed hardware and software platforms. Issuing bodies include county water departments, county public utilities divisions, and multi-department county procurement offices; Brevard County, Gwinnett County, and Hillsborough County have each posted transducer solicitations in the past two months.

Recent activity concentrates in Florida and Georgia. Brevard County is proceeding with a non-competitive single-source award to AWC Inc. for Pulsar Reflect radar level sensors (due date August 4, 2026, posted October 19, 2026). Gwinnett County Department of Water Resources issued an Informal Written Quotation (IWQ 136938) on October 5, 2026 for eight HS421 Series vibration and temperature transmitters with cable assemblies and studs, with quotes due October 12, 2026 at 3:00 p.m. and a requirement for three project references and certification of non-collusion. Hillsborough County posted a request for isolation amplifiers and Acromag isolators on August 24, 2026, with proposals due September 8, 2026; minimal technical detail is available in the public summary. A Florida county issued an RFI notice of intent to designate In-Situ Inc. pressure transducers as sole source for water-level monitoring on July 24, 2026, inviting competing vendors to submit documentation of comparable products or challenge the sole-source designation by July 31, 2026.
