VTV12A is an ATEX vibration transmitter for hazardous-area machine monitoring. It measures vibration velocity from 0 to 25 mm/s RMS. The transmitter covers a 10…1000 Hz frequency range. Its 4…20 mA output enables direct integration with industrial control systems. ATEX approvals allow use in specified hazardous environments.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
VTV12A is designed for vibration monitoring in potentially explosive environments. It uses MEMS sensing technology. The 0…25 mm/s RMS range supports standard machine condition monitoring. Its 4…20 mA output provides continuous vibration information. This supports alarm and maintenance systems.
The transmitter carries ATEX II 3D and ATEX II 3G approvals. It is suitable for specified hazardous-area applications. The operating temperature range is -20…60 °C. IP67 protection supports industrial environmental conditions. Outside hazardous areas, enhanced IP69 protection is available according to the product specification.
VTV12A uses a 4…20 mA analogue output. This makes it suitable for PLC and monitoring-system integration. The sensor follows DIN ISO 10816 vibration measurement principles. M12 connectivity supports industrial installation. The transmitter provides a compact approach to hazardous-area vibration monitoring.
