Overview

The Meggitt TQ412 111-412-000-013 Proximity Sensor is part of the Vibro-Meter® product family and is engineered for precise, non-contact displacement and vibration measurement using the eddy-current principle. It is widely used in shaft vibration monitoring, gap measurement, and rotating machinery protection systems. The TQ412 features a reverse-mount design, making it ideal for compact or restricted installations, while its integral coaxial cable reduces connection failures and simplifies wiring.

Certified for hazardous areas (Ex iA) and compliant with API 670, it is widely implemented in oil & gas, power generation, and heavy industrial sectors. Its robust construction and high accuracy make it a trusted choice for mission-critical condition monitoring applications.

Technical Data

Applications

• Shaft relative vibration monitoring in turbines, compressors, pumps, and other rotating equipment.

• Gap and position measurement for alignment, clearance tracking, and machine-protection systems.

• Condition monitoring platforms, including VM600 and VibroSmart® installations.

• Hazardous locations, where Ex-certified sensors are required for safe operation.

• Oil & gas, power generation, and heavy industry, where reliability and precision are essential.

FAQ

Q1: What makes the TQ412 different from the TQ402?
The TQ412 is optimized for reverse-mount installations, whereas the TQ402 supports standard forward-mount configurations.

Q2: Is the sensor suitable for hazardous areas?
Yes. It is Ex iA explosion-protected and certified for use in potentially explosive atmospheres.

Q3: What monitoring systems is it compatible with?
It integrates seamlessly with VM600, VibroSmart®, and other Vibro-Meter® API-670-compliant monitoring systems.

Q4: What is the operating temperature range?
It performs reliably from −40 °C to +180 °C, suitable for extreme industrial environments.

Q5: How is the sensor installed?
It uses a reverse-mount configuration with an integral coaxial cable, reducing connection points and simplifying installation.
