PS-3227 wireless sound-wave/sound-level sensor
The PS-3227 wireless sound-wave/sound-level sensor combines waveform and sound-level measurements in a compact, portable device. Students can investigate and analyze sound-wave properties such as waveform, wave speed, amplitude, frequency, and wavelength. They can study wave superposition and beats, as well as harmonic properties of standing waves and the presence of overtones. Overview: The PS-3227 combines two sensor functions in one wireless device: a sound-wave sensor measuring relative sound-pressure-level values over time, and a sound-level sensor with both dBA and dBC weighting scales. Sound-wave sensor: As sound waves reach the sensor, it measures relative changes in sound-pressure level. Graphs of sound-pressure level versus time let students investigate and analyze waveform, wave speed, amplitude, frequency, wavelength, and more. Sound-wave data work with Scope and FFT displays in both SPARKvue and Capstone. The wireless sound sensor also acquires sound-wave data wirelessly at sampling rates up to 100kHz. Sound-level sensor: It provides actual sound-level (sound-intensity) measurements with dBA and dBC weighting. The dBC scale measures sound intensity across a broad frequency band both within and beyond human hearing, while dBA filters some source frequencies to approximate the human ear's frequency response more closely. In workplaces, dBA is commonly used to assess the sound levels employees encounter in typical working conditions. Sound level and noise pollution are key environmental-science measurements. This sensor provides all the functions of a sound-level meter with wireless measurement and the added flexibility of continuous logging over time.

Fully integrated 4-channel DVS optical module
Sensors
Oe-photonics
Sensing distance: typical:20 km Number of detection channels: 4 channels Modulation mode: External modulation
For multichannel, fully integrated distributed vibration sensing (DVS), the DVS-AOM-L series uses an ultra-narrow-linewidth laser with optimized optomechanical/electrical integration. Serial-port parameter configuration, high integration, environmental-interference resistance, compact size, and convenience are provided. Sharing a narrow-linewidth laser reduces multichannel costs, particularly for demanding sensing applications. Custom solutions and specifications are available to sensor-equipment manufacturers.
