UNSPSC 41112104: Audio transducers

UNSPSC 41112104 Audio transducers, a Commodity code, encompasses specialized sensors and monitoring equipment that state and local water utilities and infrastructure departments are actively procuring for lift-station and booster-station monitoring applications. Recent solicitations show state and local governments buying radar level sensors, vibration and temperature transducers, pressure transducers, and related signal-conditioning equipment to integrate with existing water and wastewater SCADA systems. The issuing bodies include county water departments and county purchasing offices acquiring equipment for lift stations, booster stations, and water-level monitoring across surface water, groundwater, and recharge systems. Most of the recent activity involves single-source or sole-brand procurements driven by SCADA integration constraints and vendor compatibility requirements, though competitive quotation activity is also present.

Activity is concentrated in Florida and Georgia. Brevard County, Florida is proceeding with a non-competitive single-source award to AWC Inc. for Pulsar Reflect radar level sensors for lift-station monitoring, with the intended award notice posted October 19, 2026. Gwinnett County Department of Water Resources, Georgia posted an Informal Written Quotation (IWQ 136938) for vibration and temperature monitoring equipment (Model HS421 Series Transmitters, accelerometer cable assemblies, and accelerometer studs) for the Norcross Booster Station, with quotes due October 12, 2026 at 3:00 p.m. and a contact point at Jenny.Coleman@GwinnettCounty.com. Hillsborough County, Florida solicited proposals for isolation amplifiers and Acromag isolators for various county departments (RFP 26P00532), with proposals due September 8, 2026. A Florida county also posted an RFI on July 24, 2026 regarding sole-source designation of In-Situ Inc. pressure transducers and components for groundwater and surface water monitoring across water-control districts, with responses due July 31, 2026.
