66 -- ANALOG ELECTRO-HYDRAULIC SERVO CONTROL SYSTEM SOL N68335-97-Q-2551 DUE 121996 POC Debbie Dewyea Code 233DD, (908) 323-7068. Analog Electro-Hydraulic Servo Control System; 1st component of 2 component system P/N 458.20, 2nd component of 2 component system P/N 464.80. The Naval Air Warfare Center Aircraft Division Lakehurst (NAWCADLKE) intends to procure one (1) each Analog Electro-Hydraulic Servo Control System. The specification states the requirements for the control system to be used at the Enviromental Test Laboratory (ETL) operated by the Product Evaluation and Verification Department (PEVD). As a minimum, the contractual obligations of this specification are summarized as follows: 1). The delivered system shall be totally compatible with the hydraulic pumps, service manifolds, servo valves, cylinders, instrumentation, and other related components used at the ETL. The control system shall operate the hydraulic pumps and service manifolds in both high and low pressure modes and contain an emergency power off function. Signal conditioning for strain gauge load cells and Linear Variable Differential Transformers (LVDT) shall be modular, plugged into the controller console. Signal generation of ramp, sine, square, and user-programmed waveforms shall also be contained within the controller. The controller shall not require a PC to operate. 2). A data display unit able to simultaneously present two channels of the signal conditioner's output shall be included. The unit shall display minimum, maximum, and mean values of selected parameters in user-selectable engineering units. 3). Prior to acceptance, the system's operation and compatibility shall be demonstrated at the ETL. Request copies in writing or by facsimile (908) 323-2165. (0325)
