Product Overview
When reliable non-contact measurement is critical for machinery protection, the Vibro Meter 111-912-000-013-A1-B1-E1000-F0-G0-H05 Proximity Measuring System delivers precision and durability. This system from Meggitt (Vibro-Meter) uses the eddy-current principle to measure shaft displacement and vibration without physical contact. It conforms to API 670 5th edition and is suitable for functional safety contexts with SIL 2 certification per IEC 61508 and Cat 1 PL c per ISO 13849.
Key Specifications
The 111-912-000-013-A1-B1-E1000-F0-G0-H05 includes a TQ912 proximity sensor with standard environment rating (A1), M10 × 1 body thread (B1), and a 1000 mm ±100 mm integral cable (E1000). The total system length is 5 m (H05), and the sensor head is rated IP68 per IEC 60529. The system operates with a frequency response from DC to 20 kHz (−3 dB) and offers a linear measurement range of 2 or 4 mm. The sensor temperature range is −40 to 180°C operating, with short-term survival up to 220°C for 2 hours. Weight is 0.22 kg.
Industry Applications
This proximity measuring system excels in turbomachinery monitoring, including steam turbines, gas turbines, compressors, and pumps. Its non-contact eddy-current design makes it ideal for measuring shaft radial vibration and axial position in rotating equipment. The temperature-compensated design ensures stable measurements across varying thermal conditions, while the optional diagnostic circuitry detects sensor, cabling, or signal conditioner problems.
Installation and Setup
Install the sensor with the M10 × 1 thread into a suitable mounting boss. The integral cable length of 1000 mm ±100 mm provides flexibility for routing. Use the self-locking miniature coaxial connectors, hand-tightening until locked. Calibration is performed at +23°C ±5°C using VCL 140 steel target material. The system requires a high-frequency power source from an IQS900 signal conditioner, which features removable screw-terminal connectors and DIN-rail mounting.
Maintenance and Reliability
The sensor construction uses a wire coil Ø8 mm with a PPS thermoplastic tip crimped to a stainless-steel body (AISI 316L). The integral and extension cables are FEP covered 70 Ω coaxial cable. The optional flexible stainless-steel hose with FEP sheath provides sealed mechanical and electrically insulated protection. The system withstands 5 g peak vibration between 10 and 500 Hz and 15 g peak shock. Measurement drift is less than 5% for −30 to 150°C. Regular inspection of connectors and cables is recommended.
Selection Guide
When ordering the 111-912-000-013-A1-B1-E1000-F0-G0-H05, verify the total system length of 5 m meets your installation requirements. The standard environment version is suitable for most industrial settings. For hazardous areas, consider Ex-certified versions. Contact SpareTechPLC for current availability and lifecycle status before ordering.
