詳細介紹

Bruel & Kjaer 2693 /2690丹麥功率放大器 NEXUS

雙通道(單探頭)聲強調(diào)理放大器適調(diào)放大器

信號調(diào)理可以改進測量系統(tǒng)的性能和可靠性。一個典型的系統(tǒng)包括信號調(diào)理硬件，作為原始信號和傳感器輸出到測量設備之間的接口。調(diào)理放大器為系統(tǒng)提供信號放大、電絕緣、濾波、傳感器供電、過載檢測及傳感器電子數(shù)據(jù)表（TEDS）功能支持。

調(diào)理輸入的主要類型有：

傳聲器
DeltaTron?(或IEPE)
電荷
強度
橋式和差分

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)

特點

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
