Product Overview
In the demanding world of industrial machinery monitoring, the reliability of vibration and position measurement is paramount. The Vibro Meter 111-902-000-012-A1-B6-C092-D2-E500-F0-G0-H05 Proximity Measuring System addresses this need with precision and durability. As part of the renowned vibro-meter® product line, this system uses non-contact eddy-current technology to deliver accurate measurements in harsh environments. Whether for turbine shaft vibration or thrust position monitoring, this sensor chain provides consistent performance under extreme conditions.
Technical Specifications Breakdown
The 111-902-000-012-A1-B6-C092-D2-E500-F0-G0-H05 is a complete measurement chain with carefully selected components. The TQ902 proximity sensor features a 3/8″-24UNF body thread and a 92 mm body length, ensuring secure installation. The integral cable length is 500 mm ±50 mm, with a total system length of 5 meters. This system operates with a frequency response from DC to 20 kHz (−3 dB) and a linear measurement range of 2 or 4 mm, making it suitable for dynamic and static displacement measurements. The sensor withstands temperatures from −40 to 180°C operating, with short-term survival up to 220°C for 2 hours maximum. The head of the sensor is rated IP68 according to IEC 60529, offering excellent protection against dust and water ingress.
Industry Applications
This proximity measuring system excels in turbomachinery monitoring, including steam turbines, gas turbines, compressors, and pumps. Its compliance with API 670 5th edition ensures it meets industry standards for critical machinery protection. The system's SIL 2 capability in accordance with IEC 61508 and Cat 1 PL c per ISO 13849 makes it suitable for functional safety applications where reliable measurement is essential. The temperature-compensated design and current-signal transmission over distances up to 1 km allow flexible installation in large industrial plants.
Installation & Setup Guidance
Proper installation is critical for accurate measurements. The sensor body thread (3/8″-24UNF) requires matching mounting hardware. Ensure the unthreaded length of 2 mm minimum is respected to avoid interference. The integral cable with self-locking miniature coaxial connectors should be hand-tightened until locked. For Ex-zone installations, follow the temperature guidelines for the sensor and cabling as specified for potentially explosive atmospheres. System calibration is performed at +23°C ±5°C using VCL 140 steel target material. Always verify the total system length (5 m) matches your application requirements.
Maintenance & Reliability
Routine inspection of the sensor tip and cabling is recommended to ensure reliable operation. The sensor construction, with a wire coil Ø8 mm and PPS high-performance thermoplastic tip crimped to a stainless-steel body (AISI 316L), provides robustness against vibration and shock. The system withstands 5 g peak vibration between 10 and 500 Hz and 15 g peak shock acceleration. Measurement drift is less than 5% for −30 to 150°C, ensuring long-term stability. The optional diagnostic circuitry detects sensor, cabling, or signal conditioner problems, reducing unplanned downtime.
Compatibility & Integration
This proximity measuring system requires a high-frequency power source from an IQS900 signal conditioner. The IQS900 offers removable screw-terminal connectors and DIN-rail mounting for easy integration into control cabinets. The system supports voltage or current output with short-circuit protection, and current-signal transmission over distances up to 1 km. The 5 m total system length is one of the standard chain lengths available (1, 5, and 10 m).
Selection Guide & Purchasing Advice
Before ordering the 111-902-000-012-A1-B6-C092-D2-E500-F0-G0-H05, verify your application requirements: measurement range (2 or 4 mm), environmental temperature, and hazardous area certification needs. This model includes standard environmental protection (no optional protection) and no flexible hose.
