Ruby Wireless Vibration Sensor: Laboratory Precision in an Industrial Wireless Network

Eliminate unscheduled downtime without expensive cabling infrastructure. Discover the next-generation 3-axis vibration sensor featuring ISA-100.11a communication, 24-bit sampling, and up to 36 months of battery life.

In today’s industrial environment, an unscheduled outage of a critical generator set, process pump, or exhaust fan results in losses amounting to thousands of euros per hour. Traditional, wired continuous Condition Monitoring Systems (CMS) deliver top-tier signal quality; however, the installation costs of cabling, conduits, glands, and junction boxes in hard-to-reach areas often exceed the price of the sensors themselves by 3 to 5 times.

Conversely, most basic wireless IoT sensors on the market offer only compressed Root Mean Square (RMS) values—insufficient for an experienced vibration analyst to identify early-stage faults in rolling element bearings or planetary gearboxes.

The Ruby wireless measurement system eliminates this compromise. It combines uncompromising, laboratory-grade measurement precision (24-bit ADC, usable bandwidth up to 6.5 kHz, noise floor below 60 µg/√Hz) with the reliability of the industrial ISA-100.11a wireless standard and maintenance-free operation on a single battery for up to 3 years.

Why Is the Ruby System an Optimal Investment for Maintenance & Operations?

1. Up to 80% Reduction in Deployment Costs (Rapid ROI)

By eliminating the need to design and route complex cable paths, system commissioning time on-site is reduced from weeks to just a few hours. Low Total Cost of Ownership (TCO) ensures a rapid Return on Investment (ROI)—often achieved after preventing a single unscheduled breakdown.

2. Industrial-Grade Reliability via ISA-100.11a (IEC 62734)

Unlike consumer-grade Wi-Fi or Bluetooth protocols, the ISA-100 wireless mesh network is specifically engineered for harsh industrial environments. Key advantages include:

Electromagnetic Interference (EMI) Immunity: Deterministic time-slot allocation and frequency hopping ensure interference-free transmission.
Enterprise Security: AES-128 encryption and FIPS 140-2 compliance safeguard sensitive process data against unauthorized access.
Self-Healing Mesh Topology: Every sensor acts as both a measurement node and a network relay, ensuring continuous data flow even in obstructed or structurally dense plant layouts.

3. Advanced On-Board Spectral Analysis (FFT & Demodulation)

Ruby is more than just a data logger—it is a compact, high-performance signal analyzer. Its integrated ARM processor executes edge computing directly on the device:

FFT Spectral Analysis: Up to 1,800 spectral lines with block sizes up to 4,096 points.
Spectral Demodulation (Envelope Spectrum): Critical for detecting micro-cracks in bearing races and rolling elements at the earliest stages of deterioration.
Raw Time-Waveform Recording: 256 MB of non-volatile memory allows storing up to 62 million raw data points for expert post-processing.

4. Ruggedized for Demanding Industrial Environments (IP67)

Durability: The IP67-rated enclosure provides complete dust protection and water submersion resistance up to 1 meter.
Effortless Power Management: Powered by a standard, commercially available D-size 3.6V lithium battery. Intelligent deep-sleep power management drops current draw to microamps, enabling up to 36 months of operation under standard periodic measurement schedules.
