Wireless Vibration Meter Data Logger - VSEW_mk4_8G

The Vibration Meter Data Logger – VSEW_mk4 – 8g is a new model in the VSE series of smart vibration dataloggers. It can record 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 allows it to be attached to, or embedded within, the monitored equipment.

Features:

- Measures and records: Raw acceleration or velocity signals, Acceleration or velocity statistics, Vibration or velocity levels and Inclinations
- Virtual COM port interface that allows configuration and measurements to be read by a custom application 
- Added filters and settings to support the DIN4150-2 and ISO2631-2 standards directly.
- WiFi™ connection can use any open access point if the specified access point is not working (“W” model only).
- Email alerts can now be sent to multiple addresses (“W” model only).
- All-digital design.
- Integrated oscilloscope function that can show the vibration or velocity signals in real time.
- Allows the observation of recorded data while the recording is ongoing.
- Works standalone, or USB or WiFi connected for setup and data transfer to PC.
- Long life internal rechargeable battery that recharges from USB.
- Self-calibrated using the earth’s gravity as a reference.
- Observes and records 100% of the acceleration signals (no missed samples).
- Editable individual custom ID for easier instrument management.
- Completely sealed weatherproof enclosure.
