Description
The KVcam-series acoustic imaging camera is a professional product for objects localization and radiation measuring. With MEMS microphones, the acoustic sensor dynamic ranges from 30 dB to 120 dB.
KVcam-series supports audible and ultrasonic frequency bands from 2 kHz to 65 kHz, and can be used for sound source localization, abnormal sound testing, sound source trajectory tracking and positioning.
For steady-state or high transient sound sources, static or moving objects can obtain excellent detection results, and is currently mainly used in pressurized gas leakage detection and partial discharge detection of power equipment. By using a 5-inch touch screen, the results presented on the top of a cloud picture allows you to quickly find the source location.
KVcam-260 & KVcam-270 integrates acoustic and thermal camera, which support switch by software.
