The PXIe‑4492 is designed for sound and vibration applications. With a 24-bit analog input and IEPE constant current signal conditioning, the module is suitable for precision measurements in combination with microphones, accelerometers and other sensors with a large dynamic range. The PXIe‑4492 samples all channels synchronously. In addition, the module includes a built-in anti-aliasing filter that automatically adjusts to the sampling rate, six software-selectable input gain ranges, and TEDS smart sensor support to help ensure proper safety configuration. Common applications include noise, vibration and acoustic roughness (NVH) analysis, large microphone arrays, and dynamic structure testing.

PXIe-4492 vibration module is a kind of analog vibration sensor based on piezoelectric ceramic plate, which is a reverse transformation process using piezoelectric ceramics to generate vibration to electrical signals. When the piezoelectric ceramic plate vibrates, electrical signals are generated. When combined with the Arduino special sensor expansion board, the Arduino analog port can sense weak vibration electrical signals, and realize interactive works related to vibration, such as electronic drum interactive works.

In addition, the PXIe-4492 vibration module is also used in other fields, such as vibration switches, alarms, etc. The specific type of vibration module needs to be selected according to the application requirements.

There are many types of vibration modules, which can be divided into different types according to different classification standards. Here are some common categories:

According to the measurement principle: can be divided into inductive vibration sensor, capacitive vibration sensor, resistance vibration sensor and so on.

According to the output signal: can be divided into analog output and digital output two types. The analog output type vibration sensor outputs a continuously changing voltage or current signal, while the digital output type vibration sensor outputs a discrete binary signal.

According to the installation method: it can be divided into two types: built-in type and external type. The built-in vibration sensor is installed inside the device, while the external vibration sensor is installed outside the device.

According to the use environment: can be divided into land type, water type, air type and other types. The land type is suitable for land environment, the water type is suitable for underwater environment, and the air type is suitable for air environment.

In short, different types of vibration modules of PXIe-4492 have different characteristics and application scenarios, which need to be selected according to actual needs.
