Ultra fast and miniature Oxygen Concentrator Flow Rate controller & sensor with 13ms response time. 0 to 3V DC proportional flow rate control input. 0 to 3V DC oxygen concentration & flow rate proportional outputs. UART / RS-232 output provides O2 concentration, flow Rate and gas temperature. Push button switch contact enables display of O2 content, Flow Rate and Temperature on DigiDISP LCD. TUNE is ideally suited for closed loop, ultra fast Oxygen Concentrator flow rate control applications. Expanded thermal characteristics allow Automotive, high altitude and Portable Oxygen Concentrator applications. |
