丹麦 Bruel&Kjaer2690-0S2功率放大器

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
