1.新型信号适调放大器B.K.公司今年度推出Nexus—新一代的信号运调放大器系列.它的特点是装有微处理器,用于控制、显示和接口,而信号仍保持模拟量,以获得最佳信噪比和最低失真.Nexus的含义是“接口”,表明它是传感器和数据采集之间的完善的连接.它采用模块插板选件结构.每台放大器有4个输入通道,每个通道包括公共模块、可替换的输入模块、选用模块和输出模块.在进行不同类型或不同场合的测量时,有高度灵活性,可适应五种主要的声学和振动传感器:声学话筒、声强测量头.电荷加速度计、内装集成线路的加速度计及力传感器.各通道可选择使用.例如可按用户需要使用一个三向加速度计加上一个传声话筒及前置放大器等等.
1. New Signal Conditioning Amplifier BK Corporation introduced its Nexus family of next generation signal conditioning amplifiers this year featuring a microprocessor for control, display and interface while the signal remains analogue for Best signal to noise ratio and minimum distortion. Nexus means “interface”, indicating that it is the perfect connection between the sensor and data acquisition. It uses modular plug-in option structure. Each amplifier has 4 input channels, each Each channel includes a common module, a replaceable input module, an optional module, and an output module. It has the flexibility to accommodate five main types of acoustic and vibration sensors for measurements on different types or applications: Acoustic Microphones, Sound Intensity Accelerometer with integrated circuit and force sensor, each channel can choose to use, for example, according to user needs using a three-way accelerometer with a microphone and preamplifier microphone, and so on.
