Accelerometers

The Department of the Army, through Army Contracting Command Aberdeen Proving Ground, intends to sole source the procurement of Dytran Instruments, Inc. accelerometers and related hardware under FAR 12.102(a), due to the exclusive compatibility of these brand-specific sensors with existing Army vibration data acquisition systems at the Aberdeen Test Center. The acquisition includes seven distinct items: triaxial DC accelerometers with varying g-ranges (±40g, ±50g, ±200g), cable assemblies in 30ft, 50ft, and 100ft lengths with 9-pin jacks to pigtail connectors, and aluminum anodized mounting bases with tapped holes. Each sensor must meet stringent technical specifications including a sensitivity range of 2.5–20 mV/g, frequency response up to 3000 Hz, operation across extreme temperatures from -67°F to 257°F, and a shock limit of 5000 g, with hermetic sealing ensuring environmental durability. Delivery of each unit requires both a physical and electronic calibration certificate, and all items are to be delivered to Aberdeen Proving Ground, Maryland, with no alternative source deemed acceptable due to proprietary integration requirements. The solicitation, identified as ATC_Accelerometers_01, is a pre-solicitation notice with a response deadline of 0800 EST on July 29, 2026. Proposals must be submitted exclusively via email to the designated Contract Specialist and Contracting Officer. Pricing details and total contract value are not provided, but the acquisition is confirmed to be at or below the Simplified Acquisition Threshold of $250,000, justifying the sole-source approach without formal competition. No evaluation factors, contract clauses, or Section K certifications are included in the documentation, consistent with the streamlined process for below-SAT sole-source procurements. Packaging, marking, and preservation requirements are not specified, though the devices are described as commercially manufactured with inherent environmental protection. No options, security clearances, key personnel requirements, or organizational conflict of interest provisions are identified. The procurement relies entirely on Dytran’s commercial-off-the-shelf product performance and legacy system interoperability, with acceptance conducted by the Government at the delivery location after verification of technical compliance and calibration documentation.
