The MSM-2 condition monitoring sensor plays a critical role in the predictive maintenance of rotating equipment such as motors, pumps, compressors, fans, presses, and other industrial assets. By measuring vibration and temperature in real-time, the MSM-2 detects changes in operating conditions that could signal emerging faults. When abnormalities are identified, alerts are automatically triggered—enabling early intervention to reduce downtime and prevent costly failures.

The MSM-2 sensor enables accurate and consistent data collection for a wide range of assets. When integrated with Machine Sentry® software, it forms a powerful, unified platform for asset health monitoring—combining vibration analysis, temperature tracking, infrared data, and condition-based diagnostics into a single, scalable solution.

Key features of the MSM-2 include:

• A 4-channel data acquisition system, including:
  • Three internal tri-axial accelerometers for complete vibration insight
  • One external channel for additional sensors or protection panels
• High-definition waveform storage with intelligent compression for advanced post-processing
• Seamless Bluetooth® 5.2 LE connectivity with a range of up to 100 meters
• Designed for easy pairing with Android devices (version 6.0.1+)

The MSM-2 sensor connects effortlessly to your Android smartphone or tablet via Bluetooth® 5.2 Low Energy, allowing safe and efficient data collection—up to 100 meters away. This wireless capability makes the MSM-2 ideal for monitoring assets in hazardous, remote, or restricted-access areas.
