UNSPSC 41114104: Seismic amplifiers

UNSPSC 41114104 Seismic amplifiers (Commodity) covers vibration and temperature monitoring equipment that state and local governments purchase for infrastructure asset management and condition monitoring. Recent solicitations show state and local buyers acquiring accelerometers, transmitters with 4-20mA proportional output, PT100 temperature sensors, accelerometer cable assemblies with M12 connectors, and related controllers and condition monitors — components typically deployed at water utility booster stations, pumping facilities, and other critical infrastructure to detect and track equipment vibration and thermal conditions. Issuing bodies include county water resource departments and municipal utilities, which source these items both as targeted replacements for specific facilities and as stocked inventory for ongoing maintenance and asset monitoring programs.

Gwinnett County Department of Water Resources posted an Informal Written Quotation (IWQ 136938) on October 5, 2026, due October 12, 2026, for vibration and temperature sensors at the Norcross Booster Station, specifying Model HS421 Series Transmitters, accelerometer cable assemblies, and accelerometer studs with firm FOB Destination delivery to Lawrenceville, Georgia. The City of Tampa Purchasing Department posted RFQ 26-P-00545 on September 17, 2026 (due September 8, 2026) for inventory cables, connectors, controllers, and dual and multi-purpose accelerometers for distribution across multiple city departments, with one-year award period and five-business-day delivery to local sites. Both jurisdictions emphasize responsive, lowest-price awards and require proof of insurance and compliance with state labor and tax law before payment.
