Bruel & Kjaer 2693 /2690丹麦 功率放大器 NEXUS

双通道(单探头)声强调理放大器适调放大器

信号调理可以改进测量系统的性能和可靠性。一个典型的系统包括信号调理硬件,作为原始信号和传感器输出到测量设备之间的接口。调理放大器为系统提供信号放大、电绝缘、滤波、传感器供电、过载检测及传感器电子数据表(TEDS)功能支持。

调理输入的主要类型有:

  • 传声器

  • DeltaTron?(或IEPE)

  • 电荷

  • 强度

  • 桥式和差分

 

用途

  • Specially suited for automotive use. Developed in association with major car manufacturers, for high-quality field and laboratory measurement systems

  • Used with charge accelerometers, hydrophones, force transducers, condenser microphones, DeltaTron? accelerometers, DeltaTron preamplifiers, voltage input and sound intensity probes

  • Field recording of vibration and acoustic signals

  • Specially suitable for applications where shocks and impulses occur such as gas turbine testing and munitions testing (Types 2692-C and -D only)

 


特点

  • Highly flexible construction – 1, 2, 3 or 4 channel configurations, or a combination of acoustic and vibration transducer inputs is possible

  • High input signal range. Low noise. Extensive overload facilities

  • Supports transducers with TEDS according to IEEE 1451.4

  • Available for: charge, microphone, sound intensity, DeltaTron and very high input

  • Compact robust design and battery operation makes it suitable for use in the field (and in the laboratory)

  • Serial control interface (RS–232) allows computer control of setups and test functions. A large number of amplifiers can be controlled from a single PC

  • High accuracy due to reliable construction and a wide range of calibration options. Built-in patented Charge Injection Calibration (CIC) and patented Mounted Resonance Testing

  • Wide range of filters that can be set up for specific tasks

  • Rack-mounting fittings available
