WIVER is a high-performance wireless condition monitoring sensor. Coupled with MAPER’s Asset and Process Health Platform, it can provide smart insights on asset health by measuring tri-axial vibration and temperature. Its multiple configuration options allow condition monitoring of diverse machines, including highly intermittent assets which are difficult to diagnose with competing products. Multiple WIVERs can be automatically synchronized for simultaneous measurement of a given asset. MAPER offers multiple versions: WIVER standard (optimized for the most common assets in industry) and WIVER FS for highly intermittent machines. Each of these can also be configured according to the operation ambient rating: standard, HT (high temperature – up to 100°C continuous operation) and Ex for explosive atmospheres.

Easy installation in 15’.
NFC allows single-touch configuration using a cell phone.1
Multiple mounting options (adhesive base, mounting fins, screw mount, etc.)2

Measurement characteristics

The Wiver provides comprehensive vibration and temperature monitoring capabilities. For vibration analysis, the sensor captures measurements across a wide dynamic range from ±2g to ±16g with sampling rates up to 26.67 kHz. This enables detailed spectral analysis up to 13.33 kHz, with resolution as fine as 0.01 Hz for precise component identification.
The device ensures measurement reliability through multiple technical features. Temperature stability is maintained with sensitivity variation under 0.025%/°C, while measurement accuracy is guaranteed by ±2% sensitivity error and ±0.03% frequency accuracy. The tri-axial sensor provides a 6300 Hz bandwidth on all axes, with a low noise floor of 70 μg Hz-1/2 ensuring clean signal capture.

Analysis flexibility is achieved through configurable parameters. Users can select from multiple windowing options including Hann, Hamming, Flat-Top, Rectangular, and Blackman-Harris. Spectral resolution is adjustable up to 13,333 lines with customizable overlap from 0-100%. The reporting schedule can be tailored to application needs, with RMS values available every 2-15 minutes and spectral data every 2-6 hours.
Mounted on machine with standard base.
With 2x AA batteries, base (mounted on machine) not included.

Range is highly dependent on location and RF environment (eg. clearance to metallic objects, presence of walls/ceilings) and installation of the MAPER Gateway.

Temperature monitoring covers the full industrial range from -30°C to 100°C. Measurement accuracy is optimized for standard operating conditions (-10°C to 60°C) at ±3°C, with ±3.5°C accuracy maintained across the extended range. This ensures reliable temperature tracking across all operating conditions.

Radio Physical Layer Specifications

The Wiver sensor utilizes the IEEE 802.15.4-2015 O-QPSK PHY layer with Direct Sequence Spread Spectrum (DSSS) modulation. This configuration provides robust wireless communication in industrial environments:

The Offset Quadrature Phase-Shift Keying (O-QPSK) modulation, combined with DSSS, offers excellent interference resistance and efficient spectrum usage

2MHz channel spacing allows for 5 non-overlapping channels in the 915-925 MHz band, centered at 916…924MHz
Channel bandwidth of 850kHz at -6dB provides sufficient data throughput while maintaining spectral efficiency

Maximum EIRP of 50mW enables reliable communication range while meeting regulatory requirements
Power spectral density below -6 dBm/3kHz ensures minimal interference with adjacent channels and other systems

This implementation enables reliable sensor data transmission even in challenging RF environments while maintaining power efficiency for extended battery life.

NFC Interface Specifications
The device incorporates a Dynamic NFC Tag Type 5 implementing ISO/IEC 15693 for device configuration and maintenance:
