Product Description

The Wireless Vibration Meter Data Logger – VSEW_mk2 – 8g is a new model in the VSE series of smart vibration datalogers. 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 Wireless Vibration Meter Data Logger – VSEW_mk2 – 8g model is an evolution of the Vibration Sentry E model.

The VSEW_mk2 has the following new features:

  • Can measure, record and trigger on velocity signals, in addition to acceleration signals.
  • Has WiFi reporting and email alarms.
  • Includes an accelerometer with exceptional noise floor (20 times better noise floor than the Vibration Sentry E – 16g).
  • Sampling rates up to 4 kHz.
  • Improved anti-aliasing filter.

The VSEW_mk2 vibration meter data logger is ideal to monitor very low vibration levels, such as ground tremors and floor vibrations.

VSEW_mk2 Applications

  • Building-health monitoring on construction sites.
  • Long-term seismic monitoring.
  • Long-term inclination monitoring.
  • Long-term measurement and recording of acceleration signals, velocity signals, signal statistics (peaks and average) and RMS levels.
  • Continuous monitoring of machinery wear

Specifications

Number of axes 3
Acceleration Sensor MEMS 3-axes
Dynamic Range +-8 g
Bandwidth High Limit Adjustable up to 2 kHz (@ 4 kHz Sampling Rate)
Bandwidth Low Limit DC (High-Pass Filter Bypass), Adjustable from 10 mHz to Fs/2 (High-Pass Filter On)
Acceleration Noise X-Y Axes (Typical) Note: Acceleration noise is primarily affected by the sampling rate. The higher the sampling rate, the higher the noise., -82 dBg (80 μg RMS) @ 125 Hz Sampling Rate, -66 dBg (500 μg RMS) @ 4 kHz Sampling Rate
Acceleration Noise Z Axis (Typical) Note: Acceleration noise is primarily affected by the sampling rate. The higher the sampling rate, the higher the noise., -80 dBg (100 μg RMS) @ 125 Hz Sampling Rate, -64 dBg (600 μg RMS) @ 4 kHz Sampling Rate
Velocity Noise X-Y Axes (Typical) Note: Velocity noise is primarily affected by the high-pass cutoff frequency. The lower the cutoff frequency, the higher the noise., -94 dB-m/s (20 μm/s RMS) @ 1 Hz High-Pass Cutoff, -103 dB-m/s (7 μm/s RMS) @ 10 Hz High-Pass Cutoff
Velocity Noise Z Axis (Typical) Note: Velocity noise is primarily affected by the high-pass cutoff frequency. The lower the cutoff frequency, the higher the noise., -92 dB-m/s (25 μm/s RMS) @ 1 Hz High-Pass Cutoff, -101 dB-m/s (9 μm/s RMS) @ 10 Hz High-Pass Cutoff
Inclination Angle Noise Note: Measured using acceleration average, with a log interval of 1s, with the instrument positioned with the Z axis vertical, and X and Y axes horizontal, 1 E − 3°
Inclination Angle Temperature Stability Note: Measured using acceleration average, with a log interval of 1s, with the instrument positioned with the Z axis vertical, and X and Y axes horizontal, 0.2° over the temperature range -20 °C to 60 °C
Connectivity USB, WiFi
