NS航空引擎监视系统解决方案

Aircraft engines are quieter, more efficient, and more powerful due to on-board monitoring systems that optimize system efficiency. The system checks each cylinder head and exhaust gas temperature to ensure approriate levels for the manifold, oil, and ambient pressures, ambient and oil temperatures, fuel-flow, and engine RPM. From these measurements, the system determines proper air/fuel mixture conditions, calculates the engine output power, and displays the various parameters in textual and/or graphical form. A simple keypad allows user input to control the mode of operation. Serial and other communications ports allow the system to interface with other aircraft systems and to transmit data to a data logger. National provides several components that meet the stringent requirements of the aerospace industry, such as high-speed amplifiers, microprocessors, and power management devices.

Component Highlights
*Operational amplifiers - Ideal for diagnostic and sensing applications, precision operational amplifiers offer low offset and rail-to-rail input and output for best use of the supply voltage range. High-speed buffers also are available in several gains and configurations.
*DC/DC converter - offers a wide input voltage range and low noise, ideal for sensing applications and devices.
*Low-dropout regulators - provides a highly efficient solution to supply low-ripple, precise voltages to processors and DSP devices.
*RS-232 driver - the X5 receiver serial port devices have low power consumption and small footprint.
