In modern industrial environments, deploying an Industrial IoT Wireless Vibration Sensor is one of the most effective ways to detect mechanical issues before they lead to equipment failure. These sensors offer continuous condition monitoring, enabling early detection of wear, imbalance, misalignment, and bearing fatigue.
In this article, we compare three trusted sensors from NCD’s Gen 4 series — each designed for 24/7 data collection, onboard FFT analytics, and wireless cloud integration, along with real-time RPM (rotational speed) measurement.
1. Smart Vibration Sensor (Gen4)
The Smart Vibration Sensor is the most compact sensor in the lineup, making it ideal for installations where space is tight but full-spectrum monitoring is required.
Key Features:
Continuous 24/7 vibration sampling
High-resolution: 8100 samples per axis
Real-time RPM measurement
Onboard FFT and RMS calculations
Wireless communication (900MHz or 868MHz)
Long-life battery-powered
Cloud-ready (MQTT, NCD Cloud, Azure, AWS, etc.)
Best Use Case:
Ideal for monitoring motors, pumps, or rotating equipment in space-constrained areas where compact size and high data fidelity are both important.
2. Two Channel Vibration + Temperature Sensor (Gen4)
This sensor provides dual-probe monitoring — allowing you to measure and compare vibration and temperature at two separate locations on the same machine, around the clock.
Key Features:
24/7 sampling from both probes
4096 samples per axis, per channel
Built-in RPM detection
Dual temperature sensing (one per probe)
Onboard FFT and RMS
Wireless + battery-powered
Compatible with all major cloud platforms
Best Use Case:
Ideal for side-by-side diagnostics — such as comparing both ends of a shaft or motor housing vs. bearing — with synchronized RPM and vibration insight.

3. Single-Channel Vibration + Temperature Sensor (Gen4)
A streamlined, single-probe sensor that offers the same high-resolution vibration sampling and RPM data as the smart version, with the simplicity and cost-efficiency suitable for general asset monitoring.
Key Features:
Full-time 24/7 vibration monitoring
8100 samples per axis
Real-time RPM measurement
Vibration + temperature in a single probe
Onboard FFT + RMS
Wireless and long battery life
Supports MQTT, REST, NCD Cloud, and more
Best Use Case:
Designed for cost-effective condition monitoring of individual assets like fans, blowers, compressors, or pumps, where single-point data is sufficient.
