Product Introduction
When machinery vibration threatens uptime in hazardous environments, the Vibro Meter 111-402-000-013-A2-B1-C030-D000-E010-F0-G000-H10 Proximity Measuring System delivers precise, reliable measurements. This non-contact system uses the eddy-current principle to monitor shaft relative vibration and gap/position without physical contact. Part of the vibro-meter® product line from Meggitt, it is designed for machinery protection and condition monitoring in potentially explosive atmospheres.
Technical Specifications Breakdown
The 111-402-000-013-A2-B1-C030-D000-E010-F0-G000-H10 offers a comprehensive set of parameters for demanding industrial applications:
- Environment (A) : 2 = Explosive Ex i – Certified for use in hazardous areas, this system meets Ex i (intrinsic safety) requirements, ensuring safe operation in explosive gas atmospheres.
- Body thread (B) : 1 = M10 × 1 – The M10x1 thread simplifies mounting in standard sensor ports, providing a secure and repeatable installation.
- Body length (C) : 030 = 30 mm – A compact 30 mm body length allows installation in tight spaces while maintaining measurement accuracy.
- Integral cable length (E) : 010 = 1.0 m ±100 mm – The 1.0 meter integral cable reduces connection points and potential failure points, enhancing reliability.
- Total system length (H) : 10 = 10 m – The complete system extends to 10 meters, accommodating remote monitoring setups.
- Weight : 0.22 Kg – Lightweight design simplifies handling and installation.
Key Performance Characteristics
- Frequency response: DC to 20 kHz (−3 dB) – Captures both static position and dynamic vibration up to 20 kHz, essential for high-speed machinery.
- Measurement range: 2 or 4 mm – Selectable range to match shaft clearance and vibration amplitude.
- Temperature range: −40 to +180 °C – Operates reliably across extreme temperatures, with short-term survival up to +220 °C.
- Protection rating: IP68 (transducer head and integral cable) – Withstands dust and prolonged immersion, ideal for harsh environments.
Industry Applications
Shaft Vibration Monitoring in Turbomachinery
In steam turbines, gas turbines, and compressors, the 111-402-000-013-A2-B1-C030-D000-E010-F0-G000-H10 measures shaft relative vibration and axial position. Its DC to 20 kHz bandwidth captures both slow shaft movement and high-frequency vibration, enabling early detection of bearing wear or imbalance.
Hazardous Area Machinery Protection
With Ex i certification, this system is suitable for use in Zone 0, 1, or 2 explosive gas atmospheres. It integrates seamlessly with VM600Mk2/VM600 and VibroSmart® monitoring systems, providing critical data for safety and reliability.
API 670 Compliance
The system conforms to API 670 recommendations, making it a preferred choice for API-compliant machinery trains in refineries, petrochemical plants, and power generation facilities.
Installation & Setup Guidance
Mount the transducer using the M10x1 thread, ensuring the tip is positioned perpendicular to the target shaft surface. Maintain the specified gap according to the measurement range (2 or 4 mm). Connect the integral cable (1.0 m) to the extension cable using the self-locking miniature coaxial connectors – hand-tighten only until locked. The system requires a high-frequency power source from an IQS900 signal conditioner. For Ex installations, follow all local hazardous area wiring regulations.
Maintenance & Reliability
The stainless steel (AISI 316L) body and Torlon tip provide excellent corrosion resistance and mechanical strength. The IP68 rating protects against moisture and dust ingress. Regular inspection of the cable and connector for damage is recommended. The temperature-compensated design ensures drift less than 5% across the −40 to +180 °C range, reducing calibration frequency. For Ex zones, verify cable temperature rating (−40 to +195 °C) before use.
Compatibility & Integration
This proximity measuring system is designed for use with IQS900 signal conditioners and works seamlessly with VM600Mk2/VM600 and VibroSmart® machinery monitoring systems. It supports both voltage and current output with short-circuit protection. The 10 m total system length accommodates remote signal conditioning cabinets.
Selection Guide & Purchasing Advice
When ordering the 111-402-000-013-A2-B1-C030-D000-E010-F0-G000-H10, verify the following:
- Body length (30 mm) fits your mounting depth.
- Integral cable length (1.0 m) matches your routing requirements.
- Ex certification is appropriate for your area classification.
- Total system length (10 m) is sufficient for your installation.
