Acoustic Sensors in Oscilloscope Adapters to Monitor Vibrations

The PS4224-IEPE 20MHz 12bit two-channel PC oscilloscope adapter from Saelig can be deployed with an accelerometer or microphone to monitor vibrations and audio waveforms.

The Integrated Electronic Piezo Electric 1451.4 interface facilitates use of the PS4224-IEPE for mechanical analysis, while eliminating the need for external components. This interface feature is also deployed in impulse hammers, and sensors that detect sound, force and pressure. The 12bit resolution is able to identify minute incremental changes The sensors receive energy through the integrated current points located on the BNC input connector, but can alternatively deployed as a 2-channel digital storage oscilloscope through a host PC for other applications without needing further changes. It features a sampling rate of 80MSa/s and an input range of ±50mV to ±100V full-scale to detect small signals, besides higher voltages from power-supply circuits and motor drives.

The 32MSa memory is able to capture more than 400msec of data without compromising on the performance. It can be powered by a USB 2.0 port with adapters or batteries, and can be used in the field with a laptop. The integrated picoscope software uses the laptop processing power, storage, graphics and networking capabilities.
