When Shaft Vibration Data Cannot Wait
Unplanned downtime on a turbine or compressor often traces back to one weak link: a proximity probe that has drifted, failed, or was never the right fit. The 111-402-000-013-A1-B1-C040-D000-E050-F0-G000-H05 from Vibro Meter (Meggitt) is a non-contact eddy-current measuring system built to keep that link solid. It delivers shaft relative vibration and gap/position data for machinery protection and condition monitoring, and it conforms to API 670 recommendations.
This specific configuration ships with a 5.0 m ±500 mm integral cable, an M10 × 1 body thread, and a 40 mm body length. Total system length is 5 m, and the unit weighs just 0.22 kg.
Solving the Heat, the Gap, and the Connection
Pain Point 1: High-Temperature Zones
The transducer operates from −40 to +180 °C with drift under 5%. For short-term survival it handles +180 to +220 °C. When used in an Ex Zone, the transducer and cable are rated −40 to +195 °C. The cable, connector, and optional protection reach −40 to +200 °C. A temperature-compensated design keeps readings stable across that span.
Pain Point 2: Harsh Environments
The transducer head — tip and integral cable — carries an IP68 rating per IEC 60529. It withstands 5 g peak vibration from 10 to 500 Hz and 15 g peak shock (half sine-wave, 11 ms). The body is stainless steel AISI 316L with a Torlon tip and high-temperature epoxy encapsulation.
Pain Point 3: Signal Integrity
The FEP-covered 70 Ω coaxial cable (Ø3.6 mm) pairs with self-locking miniature coaxial connectors. Hand-tighten until locked. Frequency response runs DC to 20 kHz (−3 dB), with a measurement range of 2 or 4 mm. Output is voltage or current with short-circuit protection.
Where This System Earns Its Keep
This probe suits API 670 applications across oil, gas, and industrial automation. On a steam turbine, it feeds radial vibration data into a VM600Mk2 or VM600 rack. On a centrifugal compressor, it monitors axial position. With VibroSmart systems, it supports condition monitoring that flags imbalance before it becomes a failure. For teams replacing a drifted probe, matching the M10 × 1 thread and 5 m cable length avoids adapter headaches.
Fitting It Into Your Monitoring Chain
The transducer requires a high-frequency power source from an IQS900 signal conditioner. It integrates with VM600Mk2, VM600, and VibroSmart machinery monitoring systems. If your cabinet uses a different network architecture, confirm gateway and cabling needs with your supplier before ordering.
What to Verify Before You Buy
Check three things: thread size (M10 × 1), cable length (5.0 m ±500 mm), and system length (5 m). Confirm your signal conditioner is an IQS900 or equivalent high-frequency source. This unit has no flexible hose and no optional protection fitted. Please verify current lifecycle status and availability with Oil AutoTech before ordering.
Practical Maintenance Notes
Inspect the probe tip and cable periodically for mechanical damage. Keep connectors hand-tight. In high-vibration areas, check cable routing for chafing. Follow the manufacturer’s safety manual for all Ex-rated installations.
