Product Overview
When a turbine or compressor loses reliable shaft position feedback, unplanned downtime follows. The 111-412-000-013-A1-B1-E010-F0-G000-H01 from Meggitt (Vibro-Meter) is a non-contact proximity measuring system built to keep that feedback solid. It uses the eddy-current principle to measure shaft relative vibration and gap/position without touching the rotating surface. This unit comes with a 1.0 m integral cable, an M10 × 1 body thread, and a standard environment rating. It weighs just 0.22 kg, so handling and installation stay practical.
Key Parameters That Matter
Measurement Range and Frequency Response
The system offers a measurement range of 2 or 4 mm and a frequency response from DC to 20 kHz (−3 dB). That combination covers both slow gap changes and high-frequency vibration events. For API 670 machinery protection chains, this bandwidth helps capture the full picture of shaft behavior.
Temperature Capability
The transducer operates from −40 to +180 °C with drift under 5%. Short-term survival extends to +220 °C. In Ex Zone applications, the transducer and cable handle −40 to +195 °C. The cable, connector, and optional protection reach −40 to +200 °C. These ranges suit hot machinery casings and harsh plant environments.
Construction and Protection
The transducer uses a wire coil with a Torlon (polyamide-imide) tip, encapsulated in a stainless steel body (AISI 316L) with high-temperature epoxy glue. The transducer head is rated IP68 according to IEC 60529, so dust and water ingress stay under control. Integral and extension cables use FEP-covered 70 Ω coaxial cable at Ø3.6 mm. Self-locking miniature coaxial connectors hand-tighten until locked.
Where This System Fits
This proximity measuring system supports shaft relative vibration and gap/position measurement chains for machinery protection and condition monitoring. It works well with VM600Mk2/VM600 and VibroSmart machinery monitoring systems. Typical applications include steam and gas turbines, compressors, and other API 670 applications where non-contact measurement is essential. The eddy-current design means no wear from contact, which supports long-term reliability.
Integration and Setup Notes
The transducer requires a high-frequency power source from an IQS900 signal conditioner. It provides voltage or current output with short-circuit protection. When wiring into a monitoring network, confirm that your conditioner and cabling match the 70 Ω coaxial cable and self-locking connectors. If your system uses fieldbus networks, you may need an external gateway or connection module. Check cables and gateways with your supplier before commissioning.
Buyer’s Checklist
Before ordering, verify the measurement range you need (2 or 4 mm), the cable length (this unit has 1.0 m), and the thread size (M10 × 1). Confirm that your signal conditioner is an IQS900 or equivalent high-frequency power source. Also check whether your environment requires Ex certification, since Ex versions exist in this product line. The 111-412-000-013-A1-B1-E010-F0-G000-H01 ships with no flexible hose and no optional protection, so plan additional mechanical protection if your installation demands it.
