The instant requirement is for pressure sensor system for measuring underwater explosions. This purchase will consist of a multiplexer box that will record sensor data inputs as well as 5 sensors that can be positioned around the underwater blast to record pressure data in various locations to create a spatial pressure distribution map. Please see attached Solicitation and Redacted Sole Source Justificaiton for additional details.
