Wireless Vibration Meter Data Logger | VSEW mk4 40g

FCC CE ip57 waterproof

The Vibration Meter Data Logger – VSEW_mk4 – 40g 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.

The VSEW_mk4 has the following new features:

  • Virtual COM port interface that allows configuration and measurements to be read by a custom application (see VSEW_mk4_Com_Protocol.pdf)
  • 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).

VSEW_mk4 Applications

  • Long-term seismic monitoring.
  • Shipment monitoring
  • Long-term measurement and recording of acceleration signals, velocity signals, signal statistics (peaks and average) and RMS levels.
  • Continuous monitoring of machinery wear.
