VTV121 is a vibration transmitter designed for continuous machine vibration monitoring. It measures vibration velocity from 0 to 50 mm/s RMS. The sensor operates across a 10…1000 Hz frequency range according to DIN ISO 10816. A 4…20 mA output provides direct integration with control systems. MEMS technology provides compact and reliable vibration measurement.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
VTV121 measures RMS vibration velocity from 0 to 50 mm/s. The measurement range is suitable for machine condition monitoring. Its 10…1000 Hz frequency range covers common rotating machinery vibration. The sensor follows DIN ISO 10816-based monitoring principles. This supports straightforward machine health assessment.
The sensor provides a 4…20 mA analogue output. This allows direct connection to PLCs and monitoring systems. The output represents the measured vibration condition. It can be used for alarm thresholds in control systems. This reduces the need for separate signal conversion.
VTV121 uses MEMS vibration sensing technology. Its housing provides IP67/IP68/IP69K protection. The sensor operates from 9.6…32 V DC. M12 connectivity simplifies installation. The device is suitable for motors, pumps and fans.
