Overview

The Monitran 1120I Accelerometer is part of Monitran’s general‑purpose vibration sensor range. It is a constant-current accelerometer that delivers an isolated AC output, making it suitable for permanent installation on rotating machinery such as motors, pumps, fans, and compressors. The “I” in the model number indicates Isolated AC output, not “Intrinsically Safe.”

This sensor is widely used for predictive maintenance and condition monitoring, helping engineers detect early signs of mechanical issues such as bearing wear, imbalance, or misalignment.

Technical Data

Typical Applications

• Motors and pumps: Detecting imbalance, misalignment, or bearing wear.

• Fans and compressors: Monitoring vibration levels to prevent mechanical failure.

• Industrial machinery: Continuous monitoring for predictive maintenance.

• Condition monitoring systems: Integration with PLCs, DCS, and vibration analyzers.

Key Features

• Robust stainless‑steel construction for harsh environments.

• Wide frequency response (0.8 Hz – 12 kHz) for accurate vibration analysis.

• Isolated AC output ensures clean signal transmission.

• Sealed to IP67 for dust and water resistance.

• Compact footprint with top‑entry cable for easy installation.
