Stationary acoustic camera
Designed for stationary installation in explosive zones of classes 1, 2, 21 and 22 for the purpose of continuous non-contact monitoring of the condition of technical equipment by measuring the sound pressure level of acoustic noise, operational video surveillance, thermal imaging (version with a thermal imaging module) and real-time visualization of the acoustic field in the sound frequency range resulting from defects in mechanical equipment
Conforms to explosion protection marking for explosive gas environments: 1Ex eb ib mb IIС T4 Gb Х and for explosive dust environments: Ex ib mb tb IIIC T135°С Db Х
Available in two versions:
- With thermal imaging module – Explosion proof multisensor device NACEx-SA AMCSh.468266.021
- Without thermal imaging module – Explosion proof multisensor device NACEx-SA AMCSh.468266.021-01
Works as part of an acoustic monitoring system Aura AcoMS
Solves the following problems:
- Real-time asset condition monitoring
- Detection and localization of mechanical anomalies
- Setting multiple monitoring points
- Plotting graphs of acoustic and thermal picture
- Informing management services about the condition of the asset
Discover the Benefits of Using a Microphone Array in a Stationary Acoustic Camera NAC-SA through an Interactive Simulation.
Switch Between Modes Standard Microphone and Acoustic Camera, move the acoustic beam across the image and compare how the audibility of different sound sources changes.
In Conventional Microphone mode, all surrounding sounds are heard at once. In Acoustic Camera mode, the system focuses on the selected area, amplifying the sound of the target source while reducing background noise. This makes it easier to pinpoint abnormal noise sources and detect mechanical faults, bearing wear, fan and electric motor issues, pipeline problems, and other equipment anomalies - even in noisy industrial environments.
Tip: Press ▶, switch to «NAC-SA Camera» and point the beam at any sound source to hear the difference.
