The Vibration Meter Data Logger – VSEW_mk4 – 8g is a smart vibration datalogger in the VSE series. It records accelerations, vibrations, velocities and inclinations. It includes a 3-axis MEMS accelerometer, an accurate date/time clock and a non-volatile 128 Mb recording memory.
Depending on the settings, it can record acceleration or velocity signals and/or RMS levels for months. Its very small size (65 g) allows it to be attached to, or embedded within, the monitored equipment.
New in the VSEW mk4
- Virtual COM port interface for custom application integration (see VSEW_mk4 Com Protocol)
- Preset filters support DIN4150-2, DIN4150-3 and ISO 2631-2 standards
- WiFi™ auto-fallback to any open access point ("W" model only)
- Email alerts to multiple addresses ("W" model only)
Higher dynamic range needed? The VSEW mk4 40g and VSEW mk4 200g offer extended ranges for shipment monitoring and high-impact applications.
VSEW mk4 8g Applications

Built for These Applications
The VSEW mk4 8g excels in low-amplitude vibration monitoring where precision, support and long-term recording are critical.
Construction & Building Health
Monitor ground-borne vibrations from pile driving, excavation, blasting and heavy machinery near sensitive structures. The built-in preset filters support DIN4150-2, DIN4150-3 and ISO 2631-2 standards reporting without post-processing.
Seismic & Structural Monitoring
Deploy for long-term seismic recording and structural inclination monitoring. The ultra-low noise floor (200 μg RMS) detects micro-vibrations and subtle shifts that coarser sensors miss entirely.
Machine Condition Monitoring
Attach to rotating equipment, motors, HVAC systems or industrial machinery to track wear over time. The 100% duty rate and velocity measurement capability give you complete vibration profiles for predictive maintenance.
Remote & Cloud Monitoring
Pair with the 24/7 Cloud Data Access for real-time wireless monitoring. WiFi email alerts notify you instantly when vibration thresholds are exceeded at remote sites.
