AC10
Acoustic Imager
Applications
- Pressurised gas and vacuum leak detection and localisation.
- Partial discharge detection and localisation.
- Structural vibration detection and localisation.
The AC10 Acoustic Imager is a portable acoustic imaging accessory for smartphones and tablets that can be used either as a handheld unit or deployed on a tripod. With 162 high-sensitivity digital MEMS ultrasonic microphones and built-in camera, the AC10 can locate and visualise PD and other abnormal acoustic or vibration phenomena safely and efficiently.
Its microphone distribution is based on an equal area multi-arm helix, which ensures accurate acoustic positioning in the analytical frequency range of 2 kHz to 96 kHz.
Key Features
- Controlled by smartphone or tablet
- 2 kg handheld weight
- 4 hours typical battery life
- Sound analysis from 25 Hz to 96 kHz
- Positioning from 2 kHz to 96 kHz
- 4:3 camera with 66° horizontal angle of view
Using FPGA real-time signal acquisition and processing technology, the AC10 utilizes a beamforming algorithm to perform real-time imaging of sound and combines it with live camera video to generate a “sound video” to visualize the source of the detected sound.
Easy to carry and simple to operate. Controlled from the user’s smartphone or tablet using SDMT’s SmartPD application. Includes mount for phones and tablets to allow single handed operation.
Measurement frequency band, dynamic range and detection threshold can all be adjusted to accommodate different measuring environments and optimise visibility of specific acoustic sources.
Designed to work with SDMT’s other handheld PD instruments. Visualise with the AC10 and analyse with the PD74i using the same app.
