NIGP 22002: Accelerometers

NIGP 22002 Accelerometers, an Item code, covers vibration and temperature monitoring sensors and accessory equipment that state and local governments procure for infrastructure asset management and condition monitoring. State and local water utilities, in particular, buy accelerometers and related sensor assemblies to monitor the performance and structural health of pumping stations, treatment facilities, and distribution infrastructure. The code encompasses the sensors themselves, associated cable assemblies with standardized connectors, and mounting hardware such as accelerometer studs — all components needed for a complete vibration monitoring installation at critical facilities. County water departments represent the primary buyer segment for this code, driven by the need to detect anomalies in pump and motor performance before equipment failure occurs.

Gwinnett County Department of Water Resources posted an Informal Written Quotation (IWQ 136938) on October 5, 2026, due October 12, 2026, soliciting eight vibration and temperature sensor transmitters (Model HS421 Series or approved equivalent), eight accelerometer cable assemblies with M12 connectors and 150-foot PUR cable, and eight accelerometer studs with 1/4"-28UNF female glue fittings for the Norcross Booster Station. This opportunity illustrates the typical scope under the code: complete sensor kits delivered FOB Destination to a specific facility, with vendor selection on lowest responsive and responsible basis and performance requirements tied to exact model numbers or approved equivalents. Recent activity is concentrated in Georgia.
