Key features and benefits

4 IEPE input channels – consolidate multiple vibration points in a single device with option for time-synchronization using tachometer (RPM) input for applications requiring rotational speed reference
Preserves analog signal resolution – vibration spectrum and FFT data up to 40 kHz, no compromise on data quality
Trending with calculated vibration metrics – multiple bandwidths including ISO-defined frequency ranges for acceleration, velocity, and displacement, plus true peak, crest factor, and standard deviation
Broad sensor compatibility – supports general purpose, high-frequency, low-frequency, harsh-environment, and hazardous-location accelerometers
Ideal for retrofits and new installations – whether upgrading legacy vibration monitoring or deploying a new digital architecture, the VDS130 seamlessly bridges trusted IEPE sensors with MQTT-based platforms.

Device Center Overview

The VDS Device Center is a built-in, browser-based interface used to configure, monitor, and maintain the VDS130. It allows users to set network and MQTT parameters, configure per-channel measurement settings, and manage user access. An MQTT viewer shows exactly what data the device is publishing. The Device Center also supports software, firmware, and system updates, enabling commissioning and ongoing device management without external tools.

The dashboard provides live status indicators for each sensor and input channel, reflecting device and signal functionality rather than the condition of the monitored asset. These indicators confirm proper sensor operation, connectivity, and configuration. The Device Center does not perform asset health monitoring, trending, alarming, or diagnostic analysis.

What types of sensors can I connect?

The VDS130 supports 4 IEPE accelerometers and 1 tachometer (RPM) input for applications requiring rotational speed reference.

You can configure:
• Sensor type (acceleration, velocity, displacement)
• Sensitivity (1–1000 mV/unit)
• Units (g, mm/s, etc.)

You can use Wilcoxon sensors, third-party sensors, or legacy installations.

What data does the VDS130 publish?

The VDS130 publishes:

Processed condition data
• Acceleration
• Velocity
• Displacement
• Crest factor
• True peak
Raw time waveform
FFT spectrum

All data is published in structured JSON over MQTT, ready for ingestion by:
• Asset management systems
• AI models
• Cloud dashboards
• Edge analytics

Can I view the data locally?

Yes. The built-in VDS Device Center provides:
• Live channel status
• Trend plots
• MQTT viewer (shows exactly what is being published)
• Configuration tools

This makes commissioning, troubleshooting, and validation simple — no external software required.

Digital sensors play an important role in monitoring applications, but there are use cases where IEPE accelerometers provide greater diagnostic capability and signal quality. The VDS130 bridges those sensors into MQTT-based systems.

Challenge	Typical Limitation	IEPE-to-Digital Advantage
Monitoring high-speed or high-frequency assets	MEMS sensors lose accuracy or bandwidth over ~5 kHz	Frequency response to 10 kHz for the ILA and 40 kHz for the VDS, providing richer diagnostic data
Low-amplitude vibration detection	MEMS noise floor limits low-level signal capture	IEPE sensors deliver superior low-noise performance for early-fault detection
Harsh industrial environments	MEMS often limited by temperature or packaging	IEPE sensors are field-proven for heavy-duty applications, extreme conditions, and hazardous locations
Mixed or legacy asset fleets	Customers have installed IEPE sensors that won’t connect to your digital infrastructure	Adapters digitize those existing sensors and stream the data into your platform over MQTT
