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:
- Explosion proof stationary acoustic camera NACEx-SA
- Explosion proof stationary acoustic camera NACEx-SA-IR with thermal imaging module
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
